Description
Technical field
The present invention relates to field of petroleum machinery, particularly, include the whipstock helping clamp.
Background technology
Whipstock is the deflecting tool that can make boring continuous bend after the interior orientation of hole.Be provided with wedge, produce certain lateral force by specialized agency and realize directional inclination.Multiple trips tool and directional operation time can be saved with it; And can with footpath deflecting pore-forming, hole body is smoothed curve; The Drilling Techno-logical creeping into routine and be more or less the same can be adopted, without the need to increasing special installation.Continuous whipstock is generally used for deflecting at the bottom of hole; Also direct deflecting branched hole at the bottom of the artificial hole can set up at rapid hardening slurries.Be suitable for complete stratum hard and hard in 5 ~ 9 grades.
Existing whipstock can not ensure the clamping that stator is firm, thus continuous bend boring can not effectively be realized, and needs again to be retrieved by drill bit, re-starts boring, could continue work well and go down.
Summary of the invention
Technical problem to be solved by this invention is to provide the whipstock contributing to clamping, and this whipstock can ensure the clamping that stator is firm, thus realizes continuous bend boring, ensures the operating efficiency of continuous bend boring.
The present invention's adopted technical scheme that solves the problem is:
Contribute to the whipstock clamped, comprise upper bearing (metal) room, axle and sleeve, upper bearing (metal) room is arranged on above sleeve and upper bearing (metal) room and sleeve are all socketed in outside axle;
Described sleeve comprises first wedge, slide block and second wedge that connect successively from top to bottom, in first wedge, top is provided with the clutch wearing axle and mistake, clutch is fastened on axle, the below of clutch is provided with splined shaft, pressure transmission spring is also provided with between upper bearing (metal) room and sleeve, also be provided with return spring between clutch and splined shaft, the both sides, below of first wedge described are also provided with clamping projection;
Described slide block is wedge shape, and slide block is provided with roller, and roller is movably set with skid resistant course, and slide block can first wedge and second wedge slide relatively, the mating shapes of first wedge, slide block and second wedge;
The roller and the clamping projection that are provided with skid resistant course match firm whole device;
Drill bit is connected with under being also connected with short tube, short tube under axle.
During enforcement, carry out according to the normal operating principle of whipstock.And when whipstock bears axial compression, through bearing chamber, pressure transmission spring, first wedge, slide block is extruded on the one hand, produce side to clamping force, pulley is made to be fixed on hole wall, and first wedge, second wedge and drill bit move skew in the other direction to slide block, and sleeve is fixed by protruding just the assisting of clamping be arranged on first wedge, clamping projection and pulley match and make whole device firm thus.
Described pulley is more than 2 and 2.
2 and 2 the above pulleys are also connected with one outward and the clamping laminate of clamping can be assisted to cover on slide block.Clamping laminate on slide block can strengthen the firm clamping of stator further, prevents whipstock from operationally producing deflection; The setting clamping laminate in addition can also the wearing and tearing of anti-limited slip block.
The shape of described clamping laminate and the slide block plane at pulley place match, and clamping laminate corresponds to pulley and is provided with open slot.The profile design of clamping laminate also needs the mechanical property meeting shoe surface to be close to mutually with slide block, and this is close to also to comprise and the convex plane at pulley place is close to mutually to ensure good location, and open slot and pulley match.
Described drill bit is without core drill bit.
To sum up, the invention has the beneficial effects as follows:
1, the protruding and pulley of the clamping that arranges of the present invention can ensure the clamping that stator is firm, thus realizes continuous bend boring, ensures the operating efficiency of continuous bend boring.
2, structure of the present invention is simple, can effectively reduce wearing and tearing, reduce costs.
