Description
Technical field
The utility model relates to a kind of petroleum industry parts, and particularly a kind of expansion tube can drag for end block apparatus.
Background technology
When carrying out completion practice with expansion tube, being be placed in expansion tube by expansion cone often, during completion practice, arriving operating position by under expansion tube, then expansion cone being extracted out, lower drill bit in well, blocks up drill bit, then just can carry out production operation the end of by again.
Summary of the invention
Problem to be solved in the utility model is to provide for the deficiencies in the prior art, there is provided a kind of expansion tube can drag for end block apparatus, this expansion tube can drag for end block apparatus and directly after expansion tube completes completion, can take out stifled for the end, improve operating efficiency, avoid the trouble again descending drill bit.
For solving the problem, the technical scheme that the utility model adopts is:
A kind of expansion tube can drag for end block apparatus, comprises sleeve pipe, is provided with expansion tube, it is characterized in that in affiliated sleeve pipe: the bottom of described expansion tube is removably connected with the end and blocks up;
The described end, is blocked up as disc, stifled one being fixed with the end on the surface and blocking up connecting elements in the described end, and stifled another in the described end has taper seat on the surface; The bottom of described expansion tube is provided with the end of matching with taper seat and blocks up connected unit;
Have the expansion member that can move up and down along vertical direction in described expansion tube, the bottom of expansion member has the stifled taking-up in end component;
Stifled taking-up component of the described end is criss-cross buckle, and connecting elements is blocked up for cylindric in the end, and connecting elements has buckle slot.
Below the further improvement to technique scheme:
Described expansion member is taper, and expansion member comprises guide portion and conical surface portion; Described guide portion is positioned in expansion member on the position of miner diameter end, and described guide portion is provided with some guiding grooves, and described guiding groove is evenly arranged around the axis of expansion member, forms bootstrap block between two adjacent guiding grooves; Described conical surface portion is positioned on the position of close bigger diameter end in expansion member; The external surface of bootstrap block is concordant with conical surface portion.
During use, upwards promote tube connector, expansion member enters into expansion tube and moves up, and completes expansion work; After compensation completes, move down tube connector, tube connector rotates, bit operation, thus plugging block is bored process of thoroughly finishing the work; The utility model structure is simple, practical and convenient, and the subsidy time is than traditional shortening more than 60%.
Below in conjunction with accompanying drawing, the invention will be further described.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation that a kind of expansion tube of the utility model can drag for end block apparatus;
Accompanying drawing 2 is for blocking up the structural representation taking out component in the end;
Accompanying drawing 3 is for blocking up the structural representation of connecting elements in the end;
Accompanying drawing 4 is the structural representation of component.

Detailed description of the invention
Embodiment, as shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3 and accompanying drawing 4, a kind of expansion tube can drag for end block apparatus, comprises sleeve pipe 1, is provided with expansion tube 2 in affiliated sleeve pipe 1, and the bottom of described expansion tube 2 is removably connected with the end stifled 5.
The described end stifled 5 is disc, and 5 one be fixed with the end on the surface and block up connecting elements 8 is blocked up at the described end, the described end block up 5 another on the surface there is taper seat; The bottom of described expansion tube 2 is provided with the end of matching with taper seat and blocks up connected unit 6.
Have the expansion member 4 that can move up and down along vertical direction in described expansion tube 2, the bottom of expansion member 4 has the stifled taking-up in end component 7.
Stifled taking-up component 7 of the described end is criss-cross buckle, and connecting elements 8 is blocked up for cylindric in the end, connecting elements 8 has buckle slot 81, and the stifled component 7 that takes out matches with buckle slot 81 at the end.
When expansion member 4 vertically drops to certain altitude, take out component 7 and be just in time positioned at buckle slot 81, after expansion member 4 rotates to an angle, take out component 7 and fasten with buckle slot 81.
When expansion member 4 rises, the end stifled 5, together can be risen, thus take out of outside well, once complete Completion Operations.
Described expansion member 4 is taper, and expansion member 4 comprises guide portion 41 and conical surface portion 42; Described guide portion 41 is positioned in expansion member 4 on the position of miner diameter end, and described guide portion 41 is provided with some guiding grooves 47, and described guiding groove 47 is evenly arranged around the axis of expansion member 4, forms bootstrap block 44 between two adjacent guiding grooves 47; Described conical surface portion 42 is positioned on the position of close bigger diameter end in expansion member 4; The external surface of bootstrap block 44 is concordant with conical surface portion 42.
Described expansion member 4 is provided with through hole 46.
Described expansion member 4 is connected with tube connector 3; Expansion member 4 can be rotated together with tube connector 3.
During use, the utility model being placed in oil well, when carrying out completion practice, first expansion member 4 upwards being carried sound, complete the expansion to expansion tube, after expansion completes, then expansion member 4 fallen, tube connector 3 rotates, take out component 7 to fasten with buckle slot 81, then promote tube connector 3, the end stifled 5, is together lifted out outside well along with expansion member 4, once completes completion practice.
