Description
Technical field
The utility model relates to a kind of a kind of instrument that oil drilling or workover treatment are used that is used for, and particularly holds and promote a kind of power choring instrument of well head of sleeve pipe.
Background technology
Casing job is an important link in the drilling operation course, and the operation quality quality directly influences the life-span of cementing quality, oil recovery amount and oil well.In the casing job process, owing to the reason of kit directly influences cased quality and increases working strength of workers.Conventional casing job mainly adopts elevator to hold on sleeve pipe and hydraulic tongs or the Type B tong and detains, above-mentioned casing job mode, and it is big to exist labor strength, and inefficiency causes problems such as Important Project that single-suspender rig down causes and personal injury easily.And not having back-up tong sleeve pipe hydraulic tongs before 500 meters, the bottom casing string is wanted transfer, must play the cooperation of making up tong like this to fix, and has influenced cased speed to a certain extent, has increased working strength of workers.Anti-turn round formula sleeve pipe power slip and have that single elevator rises, cased function and solve the problem that no back-up tong sleeve pipe hydraulic tongs bottom casing string is wanted transfer.
At present, a kind of drill string power slip that utilizes cylinder for power is arranged, mainly comprise the big quadrel seat of two opposite openeds, it is little that big quadrel seat inwall is the bottom, the stairstepping conical surface that top is big, four slip segments that symmetry is encircled into round opening are arranged in the big quadrel seat, the upper end of slip segment is connected on the appending disk by connecting rod, be provided with two-way power cylinder in the big quadrel seat, the piston rod upper end of two-way power cylinder is connected with appending disk, appending disk is provided with the guide peg that axially parallels with big quadrel seat, be provided with the hole of matching in the big quadrel seat with guide peg, this power slip is primarily aimed at drilling rod and rises, following brill and designing can not be applicable to casing job, main existing problems, (1): power slip is not anti-turns round function, all need play the cooperation of making up tong during setting of casing and fixing; (2): casing diameter is big, and especially the casing stabbing board external diameter is big, can not pass through power slip.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and provides a kind of easy for installation, and is simple to operate, the anti-moving casing slip of formula gas/liquid of turning round that automaticity is high.
The purpose of this utility model is achieved in that a kind of anti-moving casing slip of formula gas/liquid of turning round, comprise the big quadrel seat of two opposite openeds, it is little that big quadrel seat inwall is the bottom, the stairstepping conical surface that top is big, four slip segments that symmetry is encircled into round opening are arranged in the big quadrel seat, the upper end of slip segment is connected on the appending disk by connecting rod, be provided with two-way power cylinder in the big quadrel seat, the piston rod upper end of two-way power cylinder is connected with appending disk, appending disk is provided with the guide peg that axially parallels with big quadrel seat, be provided with the hole of matching in the big quadrel seat with guide peg, the oral area that is the conical surface on the described big quadrel seat is provided with a groove, and the slip segment outer upper is provided with the projection that matches with described groove.
The utility model is installed in the rotating disk, be used for blocking and unclamping sleeve pipe, drive two-way power cylinder action by integrated gas circuit or liquid road, therefore in the casing job process, two-way power cylinder can be a cylinder, also can be hydraulic cylinder, when two-way power cylinder bottom inflow or feed liquor, piston stroking upward, piston rod promotes appending disk and drives slip segment along the quadrel seat conical surface is up greatly by connecting rod, at this moment, the round opening diameter of four slip segment formation increases to maximum gradually, gets out of the way sleeve channel; Otherwise, when top air inlet of two-way power cylinder or feed liquor, descent of piston, it is descending along the big quadrel seat conical surface that piston rod pulling appending disk drives slip segment by connecting rod, and at this moment, the round opening diameter of four slip segment formation reduces gradually, till sleeve pipe is blocked in obvolvent, this moment, the projection of slip segment outer upper dropped in the groove on the big quadrel seat, played anti-ly to turn round function, did not need during setting of casing to beat to make up tong to cooperate fixing anti-turning round; The utility model is easy for installation, and is simple to operate, the automaticity height, and labor strength is low.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the A-A revolved sectional view of Fig. 1;
Wherein, 1 guide peg; 2 big quadrel seats; 3 appending disks; 4 connecting rods; 5 slip segments; 6 gas path joint seats; 7 cylinders; 8 sleeve pipes; 9 grooves, 10 projections.
The specific embodiment
As figure, be a kind of casing slip, comprise the big quadrel seat 2 of two opposite openeds, it is little that big quadrel seat 2 inwalls are the bottom, the two-stage stairstepping conical surface that top is big, four slip segments 5 that symmetry is encircled into round opening are arranged in the big quadrel seat 2, the upper end of slip segment 5 is connected on the appending disk 3 by connecting rod 4, be provided with cylinder 7 in the big quadrel seat 2, the gas circuit of cylinder 7 can be arranged in the big quadrel seat 2, and through 6 accesses of gas path joint seat, the piston rod upper end of cylinder is connected with appending disk 3, appending disk 3 is provided with the guide peg 1 that axially parallels with big quadrel seat 2, be provided with the hole of matching with guide peg 1 in the big quadrel seat 2, the oral area that is the conical surface on the big quadrel seat 2 is provided with a groove 9, and the slip segment outer upper is provided with the projection 10 that matches with described groove 9.
This device is installed in the rotating disk, be used for blocking and unclamping sleeve pipe in the casing job process, when the cylinder bottom air inlet, piston stroking upward, piston rod promotes appending disk and drives slip segment along the quadrel seat conical surface is up greatly by connecting rod, and at this moment, the round opening diameter of four slip segment formation increases to maximum gradually, get out of the way sleeve pipe 8 passages, make the sleeve pipe 8 can be descending smoothly or promote; Otherwise, when the air inlet of cylinder top, descent of piston, piston rod spurs appending disk 3 and drives slip segments 5 along the quadrel seat conical surface is descending greatly by connecting rod 4, and at this moment, the round opening diameter of four slip segment formation reduces gradually, till sleeve pipe 8 is blocked in obvolvent, this moment, the projection 10 of slip segment outer upper dropped in the groove 9 on the big quadrel seat, played anti-ly to turn round function, did not need during setting of casing to beat to make up tong to cooperate fixing anti-turning round.
