Sprockets a and b support a second gripper chain, which is also not shown. Sprockets a and b are mounted on axle for rotation. Sprockets a and b are mounted on a drive shaft that is not visible in FIG. The drive shafts transmit power to the sprockets to turn the gripper chains.

Each end of the axles on which sprockets a and a are mounted turn in bearings that are mounted in a sliding block Each of the blocks is keyed to slide along the inside edges of openings , which are formed in the front panel and back panels a and d of case The drive shafts, on which sprockets b and b are mounted, are supported on one end by bearings mounted in a fixed as opposed to sliding fashion to the front and back panels of the case Pocket , on the front panel a, carries one set of bearings for one end of the shaft for sprocket b.

A similar pocket on the back panel carries bearings for the opposite end of the shaft for sprocket b. The other ends of the drive shafts are supported by another set of bearings that cannot be seen in these views. Mounted on the same shafts as sprockets b and b are a set of timing gears a and b. The timing gears ensure synchronous rotation of the sprockets.

The axles of sprockets b and b are coupled through transmissions a and b, respectively, to low speed, high torque, hydraulic motors that are not shown. Sprockets a and a are free to turn. Between a top of each sliding block and a top of each slot is a hydraulic jack or cylinder The jacks are used to move the axles of sprockets a and a downwardly, thereby applying greater tension to a gripper chain mounted on the sprockets.

Referring now to FIGS. Each skate a and b includes a stiff beam a and b, respectively. Behind each beam are a series of cross bars that extend from the front to the back of the case. Upper cross bars a and b and lower cross bars a and b are located at opposite ends of the beam. Cross bars a and b are further used to suspend or hang the skates within the case Each cross bar is connected to a flange that extends through opening in the front and back panels of the case Each flange is pivotally connected through a set of pins to one end of a hydraulic cylinder The hydraulic cylinders, which are seen in FIG.

As the skates are pulled together, they will press gripper chains not shown in these figures; see FIG. Flanges , which are at the ends of the top and bottom cross bars a and b, and a and b, a free to move laterally within slots to accommodate movement of the skates back and forth. Flanges , which are at the ends of cross bars a and b, includes a disk that forms a journal for turning within block Block slides along slots , which are defined in the front and back panels of the case The journalled disk permits the skates to rotate slightly about their midpoints within the case.

On the side of each beam a and b that faces the other beam are mounted a plurality of rollers In the illustrated embodiment, the plurality of rollers are mounted for rotation on a plurality of roller carriers , which in turn are retained on the beam in a manner that permits limited lateral movement and rotation. As seen best in FIG. Each axle is mounted through openings in parallel flanges of one of the roller carriers Each carrier includes a pair of flanges To retain the roller carriers, each beam has an elongated, vertical slot in which the carriers are stacked.

Also formed along the beam is a set of vertical grooves , which face inwardly, toward each other, to receive outwardly extending flanges of the carriers The slot and grooves are open at one end of each beam so that the carriers can be dropped into the slot for easy installation and removal. The thickness of the flanges are less than the widths of the grooves , thereby allowing the carrier to move laterally a limited distance and to rotate slightly with respect to the beam.

Alternately, the roller carriers may have, for example, inwardly facing flanges that engage outwardly facing grooves on the beam or that wrap behind the beam. As a further alternative, the grooves on each of the beams can, in effect, be inverted and replaced with a ridge or similar raised element that mates with a complementary groove or recessed element formed on the roller carrier.

Referring now only to FIGS. The pad can be slid into slot for easy installation and removal. The resilient pad, which runs the length of beam behind the roller carriers, permits the roller carriers to be displaced laterally toward the beam against a spring force. The resilient pad generates a large spring force when compressed. The manner in which the roller carriers are mounted to the beam pad also permits the carriers to rock, such that one roller can be displaced more than the other roller on the same carrier.

Gripper chains a and b each include a plurality of gripper elements mounted on a roller chain. The gripper elements are shaped to grip tubing as it passes between the skates a and b. Each roller chain is formed by plurality of pin link plates , link plates , and rollers Each pin link plate includes two integrated pins a and a link plate b. Rollers are mounted on each end of each pin a, between a set of link plates.

The pin also acts to retain the gripper element on the chain by passing through the gripper element. A back side of the gripper elements roll on rollers as they move across the skates. Small variations in the dimensions of each gripper element , roller carrier , and rollers , as well as variations in the dimension of the beams a and b along their respective lengths may result in a disproportionate application of force to tubing Even though each element may be made to within acceptable manufacturing tolerances, the sum of the variations may result for a given gripper element at any given location along the skate in it a gripper element sticking out further toward the pipe than other gripper elements, thereby making it difficult to apply force to other gripping elements.

At very high gripping pressures, the tubing may be deformed because of the unequal distribution of the load of the gripping forces. The strain of deformation will tend to lead to premature failure of the tubing, and may even damage the tubing. However, the resilient pad between each of the beams a and b and the roller carriers mounted on the respective beams will instead resiliently deform to the extent necessary. More gripper elements will therefore contact the tubing with the desired pressure, resulting in improved gripping of the tubing.

Although each roller carrier is shown with two rollers, one or more than two rollers could be used. Two carriers provides a wide base but allows for close spacing of the rollers and relatively fine accommodation of dimensional variations in the gripper chain along the length of the skate. Carriers with only a single roller can be used, but with a smaller base or wide spacing. Carriers with more than two rollers become long and are less able to accommodate dimensional variations that may be present between adjacent gripper elements.

The pivoting roller assembly includes a roller The roller and a bracket are mounted to one end of swing arm The swing arm pivots about the end of fixed arm Fixed arm is attached to mounting Extending from the bracket are pins , on which are stacked spring washers The stacked spring washers act as a spring to bias the roller away from the beam.

The purpose and function of the pivoting roller element is to allow the first and last rollers on the skate to deflect away from pipe as each gripper element engages and disengages tubing. When each gripper element turns into, or out of, alignment with the plane of the skate, it pivots on the last roller of the skate, namely roller During pivoting an edge of the gripper element it will tend move toward the axis of the tubing as the gripper element pivots on the roller.

Without a deflection of the pivoting roller element, this pivoting of the gripper element would tend to cause the edge of the gripper element to dig into the tubing, momentarily deforming it. However, with the pivoting roller assembly, the tubing pushes back the roller , against the force of the spring washers , as the gripper element pivots. The stack of spring washers are compressed the distance necessary to allow a gripper element to pivot into alignment under a force that does not place undue or excess strain on the tubing.

Because the spring washers will already be compressed under the load imposed by the tension in the chain, the spring constant of the stack of spring washers with this load should allow further compression to provide the clearance of the gripper elements under a force that avoids or reduces placing undue strain on the tubing.

Coiled tubing injector with improved traction. United States Patent A coiled tubing injector includes two chains mounted for continuous, opposing rotation and aligned to grip between the continuous tubing. Coiled tubing is run in and out of well bores using what are well known in the energy industry as coiled tubing injectors.

The name derives from the fact that, in well bores, the tubing must be literally forced or "injected" into the well through a sliding seal to overcome the well pressure until the weight of the tubing exceeds the force produced by the pressure acting against the cross-sectional area of the tubing. However, once the weight of the tubing overcomes the pressure, it must be supported by the injector.

The process is reversed as the tubing is removed from the well. The only method by which a continuous length of tubing can be either forced against pressure into the well, or supported while hanging in the well bore or being lowered or raised is by continuously gripping a length of the tubing just before it enters the well bore.

This is achieved by arranging two continuous chain loops on opposite sides of the tubing, in an opposing relationship. The continuous chains carry a series of gripper shoes which are pressed against opposite sides of the tubing and grip the tubing.

Each chain is stretched between a drive sprocket and an idler sprocket. At least one of the two drive sprockets is driven by a motor to turn one of the continuous chains to supply injection or pulling force. The other drive sprocket may also be driven, typically by a second motor, to drive the second chain in order to provide extra power. Coiled tubing has traditionally been used primarily for circulating fluids into the well and other work over operations, rather than drilling, because of its relatively small diameter and because it was not strong enough, especially for deep drilling.

In recent years, however coiled tubing has been increasingly used to drill well bores. For drilling, a turbine motor is suspended at the end of the tubing and is driven by mud or drilling fluid pumped down the tubing. Coiled tubing has also been used as permanent tubing in production wells. These new uses of coiled tubing have been made possible by larger, stronger coiled tubing.

To handle the longer and heavier tubing, used in drilling, an injector must be capable of carrying much greater loads. Drilling sometimes progresses very slowly. Therefore, in addition to running the pipe into and out of the hole rates measured in tens or hundreds of feet per minute, the injector must also be capable of advancing the pipe at rates measured in inches per hour. Because of the required control, power for driving an injector used for drilling is usually provided by a high speed, low torque, hydraulic motor, rather than a low speed, high torque hydraulic motor.

Low speed, high torque motors are conventionally used on injectors. A high speed, low torque motor must be coupled to the injector through a transmission with reduction gearing. As shown, for example, in FIG. Sprockets and are mounted on shafts and , respectively, and are keyed to the sprockets through splines Each shaft is journalled on frame Each chain carries a plurality of grippers As the loops of the chains turn, grippers are pressed against opposite sides of continuous tubing A high speed, low torque hydraulic motor is coupled to shaft to supply power to turn chain through a brake and planetary gear box Similarly, high speed, low torque hydraulic motor is coupled to shaft through brake and planetary gear box to drive chain The axis of each motor and planetary gear box is aligned with the axis of the shaft they turn.

Because of the diameter of the planetary gear boxes and motors, a motor and planetary gear box must be mounted on opposite sides of the chains in order to synchronize movement of the respective chains, intermeshing timing gears and are mounted on shafts and The timing gears are capable of transmitting only as much power as is required to maintain timing between the chains. As is evident from the illustration, as the sizes of the motors and gearing increase to handle larger loads, so too will the depth of the coiled tubing injector, as measured perpendicularly with respect to the plane of rotation of the sprockets and chains, in directions indicated by arrows a and b.

The invention is directed to coiled tubing injectors, particularly those used for drilling well bores, having an improved drive configuration for accommodating a larger, more powerful motor and speed-reducing transmission, as well one or more additional motors, without a corresponding increase in depth of the injector. In a conventional configuration, a larger motor will increase the depth of the injector, making transportation and set up more difficult.

Most drilling rigs were made to drill with jointed, straight pipe. They have long, narrow openings which may not be, in many cases large enough to accommodate passage of coiled tubing injectors of conventional configuration, as shown in FIG. Reassembling a large injector on a drilling rig is time consuming, often requiring special tools, and is generally undesirable. Because of its narrower profile or depth, a coiled tubing injector according to the present invention may be more readily inserted through a standard opening in a conventional drilling rig.

A coiled tubing injector according to the present configuration need not have separate timing gears. Furthermore, it does not use planetary gear transmissions. Planetary gear transmissions which are the most frequently used types of transmissions on coiled tubing injectors, tend to become overheated due to their relatively compact design and small exterior surface area. Either a larger than necessary planetary gear transmission or an oil cooling system must be employed to avoid overheating when running at high power levels, either of which increases the cost of the injector.

Since a transmission in accordance with thc present invention has a relatively larger surface area, it will have a higher thermal horsepower rating, thereby allowing it to transmit greater power. These and other aspects and advantages of the invention are described below in connection with a preferred embodiment of the invention illustrated in the accompanying drawings.

Referring to FIG. The goose-neck support includes a frame supporting a plurality of rollers Bracing extending from cage positions the goose-neck support in proper relation to the injector The cage also supports the injector for handling and providing lateral support. Legs not shown may also be attached to the corners of the bottom of the cage to stand the injector above a well head not shown.

Referring now to FIGS. Connected to each drive chain is a plurality of grippers The chains and are arranged in a conventional, opposing relationship, rotating in a substantially common plane Each drive chain is mounted on an upper drive sprocket and a lower drive sprocket. The upper drive sprockets are mounted within drive housing and are not visible in these views.

Bearing housing and each accommodates a bearing for one end of the shaft of each upper drive sprocket. The other ends of the drive sprocket shafts are supported by bearing assemblies mounted to the opposite side of drive housing Drive chain is mounted on lower drive sprocket , and drive chain is mounted on lower drive sprocket A box-shaped frame is formed from two, parallel plates and , separated by side plate and a second side plate parallel to side plate but not visible in these views.

This frame supports the drive housing and transmission gear box at its upper end, and the lower drive sprockets at its lower end. The lower drive sprockets and are connected to shafts and , respectively. Each shaft extends between the front and back panels of the frame. The end of each shaft is journalled within a carrier Each carrier is mounted so that it may slide vertically within one of four elongated slots defined in the back plate and front plate of the frame.

A hydraulic cylinder is inserted between the top of each carrier and a block connected to the frame at the top of each elongated slot. Each of cylinder applies a force to a carrier to push down the lower drive sprockets and with respect to the frame and thus also the upper drive sprockets since they are mounted in fixed relationship to the frame and thereby tension the drive chains. The frame thus carries the tensioning load.

Although not visible, coiled tubing injector includes two skates, one for each drive chain, for forcing the grippers toward each other, against the coiled tubing, as they enter the area between the two drive chains through which the coiled tubing passes. Example of such skates are shown U.
