Description
Technical field
The utility model relates to field of petroleum machinery, particularly, relates to a kind of whipstock with supplementary card locking structure.
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.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of whipstock with supplementary card locking structure, 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 technical scheme in the invention for solving the above technical problem is:
Have a whipstock for supplementary card locking structure, 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, roller 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 roller match and make whole device firm thus.
Described roller is more than 2 and 2.
2 and 2 the above rollers 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 roller place match, and clamping laminate corresponds to roller 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 roller place is close to mutually to ensure good location, and open slot and roller match.
Described drill bit is without core drill bit.
To sum up, the beneficial effects of the utility model are:
1, the protruding and roller of the clamping that arranges of the utility model can ensure the clamping that stator is firm, thus realizes continuous bend boring, ensures the operating efficiency of continuous bend boring.
2, the utility model structure is simple, can effectively reduce wearing and tearing, reduce costs.

Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, to the detailed description further of the utility model do, but embodiment of the present utility model is not limited thereto.
Embodiment 1:
As shown in Figure 1, a kind of whipstock with supplementary card locking structure, comprises upper bearing (metal) room 1, axle 2 and sleeve, and upper bearing (metal) room 1 is arranged on above sleeve and upper bearing (metal) room 1 and sleeve are all socketed in outside axle 2;
Described sleeve comprises first wedge 31, slide block 32 and second wedge 33 that connect successively from top to bottom, in first wedge 31, top is provided with the clutch 31-1 wearing axle 2 and mistake, clutch 31-1 is fastened on axle 2, the below of clutch 31-1 is provided with splined shaft 31-3, pressure transmission spring 4 is also provided with between upper bearing (metal) room 1 and sleeve, also be provided with return spring 31-2 between clutch 31-1 and splined shaft 31-3, the both sides, below of first wedge 31 described are also provided with the protruding 31-4 of clamping;
Described slide block 32 is wedge shape, and slide block 32 is provided with roller 32-1, and roller 32-1 is movably set with skid resistant course, and slide block 32 can first wedge 31 and second wedge 33 slide relatively, the mating shapes of first wedge 31, slide block 32 and second wedge 33;
