Selectably elevatable coiled tubing rig control housed within a water tank

Abstract

A mobile coiled tubing rig for the drilling and workover of wells is designed to have a control room for the coiled tubing rig positioned within a tank at the forward end of the rig during transport. The control room, stored in the empty tank during transit, is selectably elevated out of the tank to its working position during rig operation When the control room is elevated, the operator or operators of the coiled tubing rig can see the coiled tubing storage wheel and the coiled tubing injector.

1. A trailer-mounted coiled tubing rig comprising:
 a coiled tubing storage reel mounted on a trailer;  
 a coiled tubing injector;  
 an auxiliary tank; and  
 a control room selectably moved from a first stored position to a second elevated position, wherein a portion of the control room is positioned within the auxiliary tank in the first stored position and wherein a top of the control room is moved away from a bottom of the auxiliary tank until the top of the control room is positioned at a greater height from the trailer than the coiled tubing storage reel and the coiled tubing injector.  
 
     
     
       2. The trailer-mounted coiled tubing rig of  claim 1 , further comprising a lifting assembly. 
     
     
       3. The trailer-mounted coiled tubing rig of  claim 2 , wherein the lifting assembly includes a hydraulic cylinder having a cylinder body vertically traversing a center of the control room and an extendable rod attached to a bottom of the auxiliary tank. 
     
     
       4. The trailer-mounted coiled tubing rig of  claim 1 , wherein the control room is moved between the first stored position and the second elevated position by a hydraulic jack. 
     
     
       5. The trailer-mounted coiled tubing rig of  claim 1 , wherein the control room has a space frame mounted on an underside of the control room. 
     
     
       6. The trailer-mounted coiled tubing rig of  claim 1 , wherein the space frame has a lifting assembly alignment cylinder. 
     
     
       7. The trailer-mounted coiled tubing rig of  claim 1 , wherein the control room has an access panel in a floor of the control room. 
     
     
       8. The trailer-mounted coiled tubing rig of  claim 1 , wherein the auxiliary tank is sealed for holding liquids. 
     
     
       9. The trailer-mounted coiled tubing rig of  claim 1 , wherein the auxiliary tank is empty whenever the control room is in the first stored position and is selectably filled with liquid when the control room is in the second elevated position. 
     
     
       10. A trailer-mounted coiled tubing rig comprising:
 a coiled tubing storage reel mounted on a trailer bed;  
 a coiled tubing injector;  
 an auxiliary tank;  
 a control room; and  
 a lifting device for selectably moving the control room between a stored position having a portion of the control room positioned within the auxiliary tank and an elevated position wherein a top of the control room is higher above the trailer bed than the coiled tubing storage reel and the coiled tubing injector.  
 
     
     
       11. The trailer-mounted coiled tubing rig of  claim 10 , wherein the control room is moved between the stored position and the elevated position by a hydraulic jack. 
     
     
       12. The trailer-mounted coiled tubing rig of  claim 10 , wherein the lifting device includes a hydraulic cylinder having a cylinder body vertically traversing a center of the control room and an extendable rod attached to a bottom of the auxiliary tank. 
     
     
       13. The trailer-mounted coiled tubing rig of  claim 12 , wherein the control room has a space frame mounted on an underside of the control room and wherein the space frame has a lifting device alignment cylinder. 
     
     
       14. The trailer-mounted coiled tubing rig of  claim 13 , wherein the rod traverses the lifting device alignment cylinder. 
     
     
       15. The trailer-mounted coiled tubing rig of  claim 10 , wherein the control room has an access panel in a floor of the control room. 
     
     
       16. The trailer-mounted coiled tubing rig of  claim 10 , wherein the auxiliary tank is sealed for holding liquids. 
     
     
       17. The trailer-mounted coiled tubing rig of  claim 10 , wherein the auxiliary tank is empty whenever the control room is in the stored position and is selectably filled with liquid when the control room is in the elevated position. 
     
     
       18. A trailer-mounted coiled tubing rig comprising:
 a coiled tubing storage reel;  
 a coiled tubing injector;  
 an auxiliary tank having a bottom and four sides;  
 a control room having an underside and a center;  
 a space frame mounted on the underside of the control room facing the auxiliary tank, wherein the space frame has centrally positioned lifting device alignment structure; and  
 a lifting assembly including a lift assembly body positioned in the center of the control room and an extendable rod traversing the lifting device alignment structure and attached to the bottom of the auxiliary tank, the lifting assembly selectably reciprocates the control room from a first stored position to a second elevated position, wherein a portion of the control room is positioned within the auxiliary tank in the first stored position and wherein a top of the control room is moved away from a bottom of the auxiliary tank until the top of the control room is positioned at a greater height from the trailer than the coiled tubing storage reel and the coiled tubing injector.  
 
     
     
       19. The trailer-mounted coiled tubing rig of  claim 18 , wherein a bottom of the control room has an access panel providing access to the auxiliary tank. 
     
     
       20. The trailer-mounted coiled tubing rig of  claim 18 , wherein each side of the auxiliary tank has a pair of internally facing rollers that interact with an exterior of a housing of the control room or with the space frame.
