Mobile coiled tubing unit

Abstract

The present invention is directed to a mobile coiled tubing unit that has a moveable coiled tubing reel and mast. The apparatus itself can be moved laterally using retractable jacks and hydraulic cylinders. The mast is retractable into a mast sleeve. The movable nature of the elements of the apparatus allow for easier alignment with the well head and balanced transportation. The reel can also be raised to increase clearance to facilitate transportation over rough or uneven terrain.

         2 . The rig of  claim 1  wherein the mast comprises a mast base which is moveable longitudinally along the frame. 
     
     
         3 . The rig of  claim 1  erg wherein the mast assembly comprises a mast sleeve within which the mast may slide to extend or retract the mast. 
     
     
         4 . The rig of  claim 1  further comprising a plurality of retractable support jack assembly, each support jack assembly comprising a support jack and a telescoping horizontal cylinders affixed to the frame, the support jack assemblies being moveable between a horizontal storage position and a deployed position wherein the support jacks engage the ground beneath the frame, and wherein the telescoping horizontal cylinders may be used to actuate lateral movement of the frame relative the support jacks when in the deployed position. 
     
     
         5 . The rig of  claim 1  wherein the reel assembly comprises a vertical lift mechanism comprising a horizontal pivot and a hydraulic cylinder to pivotably lift or lower the reel assembly. 
     
     
         6 . The rig of  claim 1  wherein the reel assembly is mounted to a slide track on the frame, and is pushed or pulled along the slide track by a hydraulic cylinder. 
     
     
         7 . The rig of  claim 1  wherein the reel assembly comprises a reel drive comprising a rack and pinion drive driven by a hydraulic motor. 
     
     
         8 . The rig of  claim 7  wherein the reel drive comprises a drive adapter plate mounted to the drive and a complementary reel adapter plate mounted to a reel axle respectively, and further comprising a reel drive clamp which encircles the drive adapter plate and reel adapter plate. 
     
     
         9 . The rig of  claim 1  wherein the mast assembly comprises a pair of mast sleeves and a pair of parallel masts, interconnected by at least one cross member, wherein one end of the at least one cross member is pivotably attached to one mast and the other end is removably latched to the other mast. 
     
     
         10 . The rig of  claim 1  which is a wheeled trailer, 
     
     
         11 . A mobile coiled tubing rig comprising:
 (a) an elongate frame having a longitudinal axis, the frame being orientated in a substantially horizontal plane;   (b) a coiled tubing reel assembly mounted on the frame;   (c) a mast assembly comprising a mast pivotally mounted to the frame, the mast being moveable between a first closed position whereby the mast is in a substantially horizontal orientation and a second open position whereby the mast is in a substantially vertical orientation, wherein the mast assembly comprises a mast base which is moveable longitudinally along the frame; and   (d) an injector mounted on the mast, the injector being selectively movable along the length of the mast.   
     
     
         12 . The rig of  claim 11  wherein the mast assembly comprises a mast sleeve within which the mast may slide to extend or retract the mast. 
     
     
         13 . The rig of  claim 11  wherein the reel assembly is movable longitudinally along the frame, and vertically in relation to the frame. 
     
     
         14 . The rig of  claim 11  further comprising a plurality of retractable support jack assembly, each support jack assembly comprising a support jack and a telescoping horizontal cylinders affixed to the frame, the support jack assemblies being moveable between a horizontal storage position and a deployed position wherein the support jacks engage the ground beneath the frame, and wherein the telescoping horizontal cylinders may be used to actuate lateral movement of the frame relative the support jacks when in the deployed position. 
     
     
         15 . The rig of  claim 13  wherein the reel assembly comprises a vertical lift mechanism comprising a horizontal pivot and a hydraulic cylinder to pivotably lift or lower the reel assembly. 
     
     
         16 . The rig of  claim 13  wherein the reel assembly is mounted to a slide track on the frame, and is pushed or pulled along the slide track by a hydraulic cylinder. 
     
     
         17 . The rig of  claim 13  wherein the reel assembly comprises a reel drive comprising a rack and pinion drive driven by a hydraulic motor. 
     
     
         18 . The rig of  claim 17  wherein the reel drive comprises a drive adapter plate mounted to the drive and a complementary reel adapter plate mounted to a reel axle respectively, and further comprising a reel drive clamp which encircles the drive adapter plate and reel adapter plate. 
     
     
         19 . The rig of  claim 11  wherein the mast assembly comprises a pair of mast sleeves and a pair of parallel masts, interconnected by at least one cross member, wherein one end of the at least one cross member is pivotably attached to one mast and the other end is removably latched to the other mast.
