Description
Technical field
The automatic grouting equipment that the utility model uses when relating to setting of casing in a kind of petroleum industry drilling process.
Background technology
The grouting method that adopts in the general at home casing job is that sleeve pipe is fixed on the chuck, and the hand-held mud line of casing job personnel pours into mud in sleeve pipe.This setting of casing grouting method, particularly aboveground at labyrinths such as extended reach wells when operation, sleeve pipe is longer quiescent time, possibly cause accidents such as sticking card can't be lowered to.The automatic grouting EGR of present domestic use generally is external product, has following problem during it is used at the scene: 1, be furnished with the startup of going up chuck in the domestic derrick seldom, general fire hose belt automatic grouting equipment is longer, can't normally use; 2, external provisions for grouting does not have mud to return locking mechanism, causes mud to trickle down on rig floor, brings a lot of inconvenience to wellbore construction.
Summary of the invention
In order to solve the problem that existing automatic grouting EGR exists, the purpose of the utility model provides that a kind of short construction period is easy to operate, the telescopic setting of casing automatic grouting equipment of safety and environmental protection.
For this reason, the technical scheme of the utility model is following:
A kind of telescopic setting of casing is used automatic grouting equipment; Comprise tool joint, suspension ring joint, thrust disc joint and the expansion joint urceolus through being threaded successively; In said expansion joint urceolus, be provided with a telescoping mechanism and a mud returns locking mechanism, said telescoping mechanism comprises expansion joint and expansion joint spring, and said expansion joint spring is installed between expansion joint urceolus and the expansion joint; Said mud goes back to the inboard that locking mechanism is arranged on expansion joint; Comprise seal cones, steel ball, seating spring and valve seat, said seal cones is threaded with the front end of expansion joint, and said steel ball seat is on said seating spring; Rely on said seating spring to withstand in the sealing centrum and keep sealing; The other end of seating spring is fixed on the said valve seat, is formed with a valve seat erecting bed at the expansion joint middle part, and said valve seat block is fixedly connected on this erecting bed and with said expansion joint.
In addition, also be provided with a thrust disc in the outside of described thrust disc joint, said thrust disc is connected with the thrust disc joint screw thread.
In order to improve sealing, be provided with sealing ring at the connecting portion of described tool joint, suspension ring joint, thrust disc joint, expansion joint urceolus.Also be respectively arranged with sealing ring in the outside of said expansion joint and the outside of seal cones.
In this automatic grouting equipment, mud returns locking mechanism and can avoid in filling process mud remaining in the pipeline to be scattered on the offshore boring island; Telescoping mechanism can reduce mud and splash, and reaches the effect of clean environment firendly, improves constructor's operating environment; The thrust disc adjustable height when on extended reach well, running into the well section that sleeve pipe can not be lowered to smoothly, can promote sleeve pipe and be lowered to through driving the top or the weight of hook is added on the thrust disc.

The specific embodiment
Below in conjunction with accompanying drawing and embodiment the structure of the utility model is elaborated.
Telescopic setting of casing shown in Figure 1 with automatic grouting equipment by tool joint 1, suspension ring joint 3, thrust disc 5, thrust disc joint 7, expansion joint urceolus 8 successively through being threaded, be respectively arranged with sealing ring 2,4 and 6 at the connecting portion of tool joint 1, suspension ring joint 3, thrust disc 5, thrust disc joint 7.During use, can tool joint 1 be driven with the top or hook links to each other according to the derrick type.In expansion joint urceolus 8, be provided with a telescoping mechanism and a mud returns locking mechanism.This telescoping mechanism is made up of sealing ring 9, expansion joint 13, expansion joint spring 14, keeps sealing through sealing ring 9 between expansion joint 13 and the expansion joint urceolus 8, and expansion joint spring 14 is installed between expansion joint urceolus 8 and the expansion joint 13.Mud goes back to the inboard that locking mechanism is arranged on expansion joint 13; Form by seal cones 10, steel ball 11, sealing ring 12, seating spring 15 and valve seat 16; Seal cones 10 is connected with the front portion of expansion joint 13 through screw thread, relies on sealing ring 12 maintenances to seal, and 11 of steel balls are on seating spring 15; Rely on seating spring 15 to withstand in the sealing centrum 10 and keep sealing, the other end of seating spring 15 is fixed on the valve seat 16.Be formed with a valve seat erecting bed (not marking among the figure) at expansion joint 13 middle parts, 16 of valve seats are fixed on this erecting bed and with expansion joint 13 welding.
Because thrust disc 5 is threaded with thrust disc joint 7, so the adjustable height of thrust disc 5.When on extended reach well, running into the well section that sleeve pipe can not be lowered to smoothly, can promote sleeve pipe and be lowered to through driving the top or the weight of hook is added on the thrust disc.
At first lift by crane installation in the construction at the scene, the tool joint on this automatic grouting equipment 1 is driven with the top or hook links to each other, and tighten the drilling rod button according to the drilling rod prescribed torque.After installing automatic grouting equipment, can normally carry out casing job,, can be in the milk to sleeve pipe at any time along with being lowered to of sleeve pipe.Expansion joint 13 moves down under the impact of mud with steel ball 11 during grouting, because the two lifting surface area is different, belongs to and forms pressure differential between the two, and steel ball 11 is stressed relatively large, produces relative displacement with expansion joint 13, thereby opens grouting channel; On the other hand, the moving down of expansion joint 13 make its can near or stretch into following sleeve box cupling, can reduce or prevent the joint leadkage of mud from two pipes.
By the time sleeve pipe when well head is opened elevator and changed an other sleeve pipe, stops grouting down, expansion joint 13 and steel ball 11 resilience under the effect of spring, and steel ball 11 cuts out grouting channel, and residual mud is stayed in the pipeline, avoids being scattered on the rig floor.
