Employing the utility model has the advantage of:
One, the utility model comprises the jointing that is in turn connected into one, upper drag reduction conical body, cylindrical body and lower drag reduction conical body, jointing, upper drag reduction conical body, the inner chamber of cylindrical body and lower drag reduction conical body is communicated with, in upper drag reduction conical body, be provided with to the first nozzle of well head direction hydrojet, the middle part of lower drag reduction conical body is provided with to the second nozzle of the borehole wall and well head direction hydrojet, the end of lower drag reduction conical body is provided with the 3rd nozzle to shaft bottom hydrojet, adopt this structure, can be at straight well, in high angle hole or horizontal well, realize bridging plug defragmentation, fragment can be returned fast and drains into ground, guarantee that pit shaft is clean, unimpeded.
Two, in the utility model, three of bottoms of lower drag reduction conical body nozzle forms three High-Pressure Waters that direction is sprayed to shaft bottom, the bridging plug fragment that is settled down to horizontal wellbore section is washed to horizontal well barrel, be suspended in well liquid, three directions are sprayed, guarantee that each orientation fragment can be washed into, and stable suspersion; , because cleaning tool has liquid ejection forward all the time, bridging plug fragment, chip or sand are rushed meanwhile, effectively avoid fragment flushing tool to insert in a large amount of fragments and cause lock of tool drilling to occur.
Three,, in the utility model, the nozzle of six helical arrangement in lower drag reduction conical body side, forms to the borehole wall and well head direction 360 degree and is uniformly distributed, and acts on the fragment fluid column that nozzle punching band suspends effectively, comprehensively; Backward, return liquid and have swabbing action, the fragment effectively nozzle punching band being suspended carries toward well head direction; The combination of second nozzle and the 3rd nozzle, being conducive to spray liquid forms large pressure reduction, high velocity liquid stream fragment spiral speedup is carried on the first nozzle liquid stream and is returned in the zone of action, as far as possible the punching of bridging plug fragment is brought to away from flushing tool outer wall and coiled tubing wall, to coiled tubing and sleeve pipe annular space, effectively prevent that lock of tool drilling from occurring.
Four, in the utility model, lower drag reduction conical body can reduce flushing tool to fragment active force angle, simultaneously, ground continuous oil pipe device suspending weight is changed more obvious, effectively anti-sticking, after bit freezing, need to carry in unfreezing tonnage less, the 3rd nozzle punching band suspension fragment returns on more easily under second nozzle effect and enters coiled tubing and sleeve pipe annular space.
Five, in the utility model, cylindrical body is without the design of nozzle, shiny surface, makes fragment be subject to liquid stream ejection side at cylindrical body and sleeve pipe annular space almost nil to active force, thereby, more easily, return in the useful effect region that enters into the first nozzle, effectively reduce fragment bit freezing risk; Meanwhile, the instrument that can play is placed in the middle and increase the effect of instrument intensity, avoids conical body to be close to casing wall wearing and tearing, guarantees that second nozzle and the 3rd nozzle ejection liquid are all the time in direction effectively and reasonably.
Six, in the utility model, High-Pressure Water is through four nozzles of upper drag reduction conical body, form the High-Pressure Water to well head direction spray back, upper drag reduction conical body is according to hole condition, can select the first nozzle of different specification size to be installed in nozzle cage, backward, hydrojet obliquely, on guaranteeing, return and carry fragment liquid and there is optimized discharge capacity and speed.
Seven, the utility model is compared and in cylindrical body, is designed nozzle, conical body top nozzle size design is larger, can obtain higher ejection discharge capacity and speed, the larger liquid spray angle that sprays to coiled tubing and casing annulus, thereby, can effectively reduce the friction probability of liquid stream, fragment and coiled tubing and sleeve pipe, reduce liquid stream and fragment friction loss, obtain larger upward velocity.
To sum up, the utility model patent principle is clear, be skillfully constructed, simple in structure, volume is little, efficiency is high, fast demountable moves, strong adaptability, safe and reliable, be applicable to cleaning dissimilar, different-grain diameter drilling cuttings, the requirement of cleaning continuous tubing drill mill bridging plug fragment can be met, Oil/gas Well down-hole fragment, chip, sand and impurity prune job under all kinds and condition can be widely used in.
