Description
Technical field
The utility model relates to industrial gas oil cover and damages subsidy and completion field, particularly stifled solid expandable tubular expansion construction tool at the bottom of a kind of reducing, detachable emission cavity.
Background technology
Solid expansion pipe SET (Solid Expandable Tubular) technology is exactly under expandable sleeve, under Oil/gas Well, after precalculated position, to utilize hydraulic-driven power or mechanical force promote or pull expansion cone to make casing string be expanded radially into a kind of drilling well, completion and the well workover new technology of desired diameter dimension.This technology has been successfully applied to drilling well, completion, well workover and oil recovery technique field at present, has developed into effective new technique that solves complex formation situation in oil, gas well drilling process.
The expansion tube construction tool of current domestic use, cone is mostly monolithic construction, cannot realize reducing and expand, make expansion tube be lowered to or expansion process in the risk that is easily hampered; Simultaneously monolithic construction cannot realize single diameter expansion, cannot reach expansion tube shutoff bore hole stratum and the object of not losing borehole size.In addition, at present both at home and abroad in expansion tube construction operation process, for processing method stifled at the bottom of expansion tube, mostly adopt the mode of falling of directly boring, therefore block up and cannot recycle at the end, and this processing mode has caused certain waste, has also increased construction working amount simultaneously.
Utility model content
The purpose of this utility model is to provide a kind of reducing, the stifled removable solid expandable tubular expansion construction tool in the end.Can overcome the deficiency of above-mentioned prior art, can reduce that expansion tube is lowered to or the risk that is hampered of expansion process, and, stifledly at the bottom of detachable expansion tube can realize recycling.
Technical solution of the present utility model is as follows: a kind of solid expandable tubular expansion construction tool, comprise solid expandable tubular (3), movable expansion gear (4), expansion gear pusher (5), end block apparatus (7), in solid expandable tubular (3), be provided with movable expansion gear (4), movable expansion gear (4) is connected with oil pipe note or drilling rod (1) by screw thread, movable expansion gear (4) bottom is provided with expansion gear pusher (5), in expansion gear pusher (5), be provided with end block apparatus (7), end block apparatus (7) is provided with central fluid channel (11) and lateral fluid port (12), end block apparatus (7) bottom is provided with the stifled ball (9) in the end, solid expandable tubular (3) bottom is provided with float shoe (8), end block apparatus (7) is embedded on float shoe (8) by conical contact face, between the two, be provided with sealing ring.
Movable expansion gear (4) is provided with wedge-shaped bead, and expansion gear pusher (5) is arranged in wedge-shaped bead.
Expansion gear pusher (5) and end block apparatus (7) are provided with flange, and expansion gear pusher (5) flange is arranged on end block apparatus (7) flange.
The utility model has solved that solid expandable tubular is lowered to or the problem that is hampered of expansion process, can realize stifled recycling at the bottom of expansion tube simultaneously.Improved the security reliability of expansion tube construction operation, can effectively reduce cost, improved the success rate of construction operation, had broad application prospects simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the utility model expansion operation structure schematic diagram.
In figure:
1-oil pipe note or drilling rod; 2-caulking gum; 3-solid expandable tubular; The movable expansion gear of 4-; 5-expansion gear pusher; 6-hydraulic cavities; Block apparatus at the bottom of 7-; 8-float shoe; Stifled ball at the bottom of 9-; The movable expanding block linking springs of 10-; 11-central fluid channel; Block apparatus fluid side passage at the bottom of 12-.
The specific embodiment
Now by reference to the accompanying drawings the utility model is further described.
Described solid expandable tubular expansion construction tool is noted by oil pipe or drilling rod 1 is sent into underground work, movable expansion gear 4 is connected with oil pipe note or drilling rod 1 by screw thread, movable expansion gear 4 connects expanding block by spring 10 and controls its radial contraction, and there is wedge-shaped bead movable expansion gear 4 lower ends, on movable expansion gear 4 lower wedge flanges, be provided with expansion gear pusher 5, the disposed inboard of expansion gear pusher 5 has flange, on end block apparatus 7, be furnished with central fluid channel 11 and lateral fluid port 12, above the top of end block apparatus 7 and lateral fluid port 12, be furnished with flange, expansion gear pusher 5 flange sleeves are on end block apparatus 7 flanges, block apparatus 7 bottoms in the end are provided with the stifled ball 9 in the end, taper surface is arranged at the bottom of end block apparatus 7, solid expandable tubular 3 bottoms are provided with float shoe 8, end block apparatus 7 is embedded on float shoe 8 by taper surface, between end block apparatus 7 and float shoe 8, by sealing ring, seal, float shoe 8 is threaded connection the bottom at solid expandable tubular 3, in solid expandable tubular 3, be provided with movable expansion gear 4, in the upper end of solid expandable tubular 3, there is caulking gum 2.
In construction operation, above-mentioned expansion construction tool is lowered into after well, if carry out completion practice, first need to return cement by central fluid channel 11, after returning cement and completing or at cover, damage in subsidy operation, directly the stifled ball in the end is dropped in end block apparatus 7, downward pathway closure now, fluid enters both sides by lateral fluid port 12, between end block apparatus 7 and expansion gear pusher 5, form hydraulic cavities, by continuous pressurization, expansion gear pusher 5 moves up movable expansion gear 4 is strutted, now expansion gear pusher 5 and movable expansion gear 4 form expansion cone jointly, expansion cone contacts with the inwall of solid expandable tubular 3, under the effect of radial pressure, make solid expandable tubular 3 that plastic strain radially occurs, while occurring that obstacle or abnormal conditions are obstructed in expanding, by pressure release, can make expansion gear pusher 5 move down, and then movable expansion gear 4 radially bounces back, stuck phenomenon can not occur.The upper end of solid expandable tubular 3 sticks together by caulking gum 2 and outer layer sleeve after expanding; After expansion has been constructed, by on carry oil pipe note or drilling rod 1 movable expansion gear 4 carried on together, movable expansion gear 4 will be carried on together with expansion gear pusher 5 by flange, the flange on expansion gear pusher 5 tops coordinates and can on end block apparatus 7 is together with internal ball 9, carry with the flange of end block apparatus 7, therefore owing to sealing by sealing ring between end block apparatus 7 and float shoe, carry on and in process, do not have excessive resistance.
