The device provided by the invention cooperates with equipment operating under pressure, a perforating gun body is clamped by the slip at the lower part of the blowout control barrel, and the rotating bearing is mounted between the lifting head and the blowout control barrel so that the lifting head and the blowout control barrel rotate relative to each other to achieve the purpose of pulling out a perforating operation tubular column and the perforating gun body separately during operation construction under pressure, avoid blowout operation and realize safety production.
Description
Technical field
The invention discloses a kind of oil water well working with pressure perforation gun apparatus, belong to oilfield downhole operation special purpose device technical field.
Background technology
In field produces, for making oil reservoir and pit shaft UNICOM, perforating gun need be utilized to implement perforating job to sleeve pipe and oil reservoir.After to oil-water well perforation, because operation wellhead exists pressure, kill-job measure need be taked or directly emit spray operation.Spray operation is emitted to there is larger potential safety hazard; Kill-job measure easily causes formation contaminant, affects oil well output, increases water filling pump pressure.In prior art, when no killing well, general employing Operating Pressure equipment lifting perforating job down-hole string and the perforating gun body of a gun, because perforating gun is after completing perforating job, its rifle body can leave over loophole, make the inside and outside connection of perforating gun, cause the preventer of Operating Pressure equipment when sealing perforating gun, liquid in well below preventer packing unit, overflow in the loophole of the perforating gun more than perforating gun inner chamber and preventer packing unit, cause sealing unsuccessfully, if by force perforating gun is tripped out under these circumstances, then can cause well head generation blowout phenomenon, severe contamination operating environment, impact safety in production.
Summary of the invention
The object of the invention is to overcome above-mentioned prior art in the construction of lifting perforating job tubing string, the shaft mouth operation environment pollution of existence is serious, the defect of impact safety in production, promotes the device of perforating job perforating gun under providing a kind of situation with pressure.
The present invention is made up of poppet, blowout prevention cylindrical shell, blowout prevention cylindrical shell bottom is slips, and slips comprises slip spider, slip insert, and the inner tubal wall of slip spider has at least two back taper draw-in grooves, slip insert is placed in draw-in groove, is provided with swivel bearing between blowout prevention cylindrical shell top and poppet.
Described poppet is " convex " character form structure; Blowout prevention cylindrical shell upper surface has the hollow hole with the lifting arm matched in clearance of poppet; Blowout prevention cylindrical shell upper end is overlapped on the table top of poppet bottom by swivel bearing.
Described blowout prevention cylindrical shell upper end is installed with plug, and plug top is overlapped on the table top of poppet bottom by pressure cap, pressure cap and be all provided with swivel bearing between plug and poppet bottom table top.
Described blowout prevention cylindrical shell bottom is installed with guide shoe.
The present invention is coordinated by Operating Pressure equipment, the slips of its blowout prevention cylindrical shell bottom is made to block perforating gun, by installing swivel bearing between poppet and blowout prevention cylindrical shell, and make it relatively rotate, reach perforating job tubing string and the perforating gun object that split trips out when Operating Pressure is constructed, avoid emitting spray operation, realize safety in production.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is A-A sectional view in Fig. 1.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described:
As seen from Figure 1, Figure 2, the present invention is made up of poppet 1, blowout prevention cylindrical shell 2, blowout prevention cylindrical shell 2 bottom is slips, slips comprises slip spider 3, slip insert 4, the inner tubal wall of slip spider 3 has at least two back taper draw-in grooves 5, slip insert 4 is placed in draw-in groove 5, is provided with swivel bearing 6 between blowout prevention cylindrical shell 2 top and poppet 1.
Described poppet 1 is " convex " character form structure; Blowout prevention cylindrical shell 2 upper surface has the hollow hole with the lifting arm matched in clearance of poppet 1; Blowout prevention cylindrical shell 2 upper end is overlapped on the table top of poppet 1 bottom by swivel bearing 6.
Described blowout prevention cylindrical shell 1 upper end is installed with plug 7, and plug 7 top is overlapped on the table top of poppet 1 bottom by pressure cap 8, pressure cap 8 and be all provided with swivel bearing 6 between plug 7 and poppet 1 bottom table top.
Described blowout prevention cylindrical shell 2 bottom is installed with guide shoe 9, and bootable perforating gun enters in blowout prevention cylindrical shell 2 cavity.
When using Operating Pressure equipment to play perforation pipe to perforating gun 10: block perforating gun 10 with the safety slip below full envelope blowout preventer position, reversion oil pipe carries out shackle to perforating gun 10 and oil pipe junction, then flowline is played, close and entirely seal blowout preventer, drive annular preventer, poppet 1 of the present invention is blocked by G.I.H of the present invention again with the traveling slip of equipment with pressure, when its guide shoe 9 is by after annular preventer, close annular preventer, open and entirely seal blowout preventer, the present invention is entered under continuation, rotate forward blowout prevention cylindrical shell 2 simultaneously, under the effect of guide shoe 9, perforating gun 10 in well is introduced in blowout prevention cylindrical shell 2 cavity, the present invention is entered under continuation, perforating gun 10 is fully contacted with slip insert 4, with traveling slip being carried poppet 1, slip insert 4 is made tightly to bite perforating gun 10, open safety slip, the present invention is proposed in continuation, the present invention will drive body of perforating gun 10 in well up together, go upward to guide shoe 9 of the present invention to seal after between blowout preventer and annular blowout prevention complete, perforating gun 10 is blocked with safety slip, perforating gun 10 is made to keep fixing, transfer the present invention, slip insert 4 of the present invention is separated with perforating gun 10, when continuing to transfer the present invention to perforating gun 10 junction, open the safety slip of Operating Pressure equipment, on propose the present invention.By described step repeatedly on carry, transfer the present invention, and coordinate with the safety slip of Operating Pressure equipment, first segment perforating gun 10 is made all to enter blowout prevention cylindrical shell 2 of the present invention inner, next joint perforating gun 10 is blocked again with the safety slip of Operating Pressure equipment, rotating spray-proof cylindrical shell 2 pairs of perforating gun 10 threads implement back-off, on propose the present invention, after guide shoe 9 of the present invention is between full envelope blowout preventer and annular blowout prevention, Guan Quan seals blowout preventer, drive annular preventer, trip out first segment perforating gun 10, high-pressure fluid in blowout prevention cylindrical shell 2 of the present invention, overflowed by the gap of slip spider 3 with perforating gun 10, avoid the generation of well head blowout phenomenon, realize the object of safety in production.
Repeat above-mentioned steps, until residue perforating gun 10 is all tripped out in well.
