Abstract
The invention relates to an abrasive jet processing tool for downhole accidents, which comprises a power device, a central shaft, a cutting head, a sleeve and a connecting short piece. The power device comprises a worm wheel and a damping fluid reducer. The cutting head of a cutter can be driven by a worm wheel rotor to rotate and the rotating speed of the cutting head of the cutter can be adjusted by the reducer. The abrasive jet cutting tool is provided with cutting heads in various dimensions. The cutting head is provided with an abrasive jet high-pressure wear-resisting nozzle. The central shaft is fixed in a lower sleeve by a thrust ball bearing. The abrasive jet processing tool for the downhole accidents is small in outer diameter, simple in structure, high in cutting efficiency and level in cut, and the deficiencies that conventional cutting tools cannot go into the conventional drill pipe and pipeline in the downhole accidents such as collapse and jamming of the drilling tool, and sand blocking of pipeline and the like are overcome, the cutting efficiency is high, and the period for processing the downhole accidents is greatly shortened.
Description
Technical field:
The present invention relates to a kind of down-hole accident abradant jet handling implement, be applicable to the processing of the down-hole accidents such as bit freezing and the serious sand card of oil pipe that cave in.
Background technology:
The bit freezing that in petroleum drilling engineering, occurs caving in has the possibility that full well is scrapped; And the down-hole bit freezing may cause drilling tool to be buried to stay and forms fish in the well that has been drilled in the process of coal-bed gas exploitation wellbore construction, and sand production too much can cause the stratum stuck oil pipe that collapses aspect petroleum production engineering.Handle that the normal instrument that uses of above accident comprises that die nipple is salvaged, female coupling tap is salvaged, in the jarring releasing on hit unfreezing and under hit unfreezing, milling junk and breakouting pack of dynamite etc.Above handling implement can be handled to general down-hole accident, but then has no idea to solve to above-described more serious down-hole accident.Serious down-hole accident adopts mechanical type inscribe cutter, magnesium powder incised instrument and back-off operation etc. often more than handling, and above instrument exists torque uncontrollable, and otch is not neat, and external diameter such as can't be lowered in the conventional drilling rod oil pipe too greatly at shortcoming.
Summary of the invention:
The object of the invention: be to provide a kind of down-hole accident abradant jet handling implement, be applicable to the instrument of down-hole accidents such as handling bit freezing and sand card.Utilize the instrument of the conventional drilling rod of abradant jet incised, oil pipe and other petroleum pipeline posts; Cutting mode of the present invention is " incised; cold cut is cut " mode, has avoided traditional machinery knives and releasing tool because external diameter more greatly can't running string inside and the not neat defective of well shooting instrument cutting mouth; The present invention simultaneously designs the cutting head of different size, and spray is high more apart from more little cutting efficiency, guarantees that the oil tubing string time spent of cutting different size is the shortest.
Characteristic of the present invention: the present invention relates to a kind of abradant jet cutting tool of handling down-hole accident, comprise power set, central axis, cutting head, sleeve, connection pipe nipple; Said abradant jet cutting tool is furnished with the cutting head of multiple size, and abradant jet high-pressure anti-wear nozzle is installed on the said cutting head; Described power set comprise turbine, damping fluid deceleration device; The cutting head of said cutting tool can be rotated motion under turbine rotor drives, its rotating speed can be regulated by deceleration device; Said central axis is fixed in the sleeve by thrust bearing.
Advantage of the present invention: outside dimension is little; Simple in structure, cutting efficiency is high, otch is smooth; Can handle various conventional oil tubing string accidents; Overcome conventional cutting tool when drilling rod caves in down-hole accident such as bit freezing, the serious sand card of oil pipe and can't be lowered to conventional drilling rod, the inner defective of oil pipe handling, cutting efficiency is high, has shortened the cycle of handling down-hole accident greatly.
Description of drawings:
Fig. 1 is a down-hole accident abradant jet handling implement structural representation.
Fig. 2 is the cutting head sectional view.
The specific embodiment:
With reference to legend, down-hole accident abradant jet handling implement provided by the invention, dynamical system comprises turbine stator 3, turbine rotor 4, deceleration device 10.Linkage comprises connection pipe nipple 8, cooperates joint 14.
Described turbine stator 3 is fixed on the upper bush 5 through circlip 2, and central axis 13 and turbine rotor 4 are through being threaded, and central axis 13 lower ends are connected with rotary cutting head 15 through cooperating joint 14.Central axis 13 is installed two thrust bearings 11, and thrust bearing 11 is fixed in the lower sleeve 9 with bottom end cover 12 through connecting pipe nipple 8.Abrasive makes central axis 13 rotations through turbine stator 3 and turbine rotor 4, and central axis 13 driven rotary cutting heads 15 are done dead axle and rotatablely moved, and the damping fluid deceleration device 10 through having groove is controlled at per minute ten right side of turning left with rotating speed.
The high-pressure abrasive material fluid line is connected with cutting tool through tubing thread 1, and abradant jet cutting nozzles 16 is installed on the rotary cutting head 15, and abrasive can form the high speed abradant jet after quickening through nozzle 16.
Cutting tool uses axle to seal as sand control with O RunddichtringO 7 with L shaped combined seal ring 6.
The cutting head that has designed a series of different sizes is to adapt to the tubing string of different size.
The above is merely the most representative embodiment of the present invention, and is all according to the equalization variation and modification done in the claim of the present invention, all should belong to covering scope of the present invention.
Claims (2)
1. a down-hole accident abradant jet handling implement comprises rotary power unit, sleeve, sealing device and rotary cutting head, it is characterized in that: said power set comprise turbine and damping fluid reducer; Said cutting tool can connect the different size cutting head, changes according to the petroleum pipeline column internal diameter that is cut; Said rotary power unit connects through being connected pipe nipple with sleeve.
2. abradant jet cutting tool according to claim 1 is characterized in that: said abradant jet cutting tool is fixed on lower sleeve through thrust bearing with hollow center shaft, and the bearing of lower sleeve lower end is fixed by bottom end cover; The bearing of upper end is fixed by connecting pipe nipple; Central axis between two bearings partly has vertical groove, makes central axis and damping fluid that bigger contact area arranged, and forms the stronger speed control unit of adjusting power; Upper bush is connected with lower sleeve through connecting pipe nipple; Central axis top is in upper bush, and the upper end car of central axis has screw thread, and turbine rotor is fixed on the central axis through screw thread; Turbine rotor is fixed in upper bush top by circlip; Cutting head is installed in the central axis lower end, is connected with central axis through cooperating joint, has the abrasive inlet on the central axis; Abrasive gets into cutting head through the central axis cavity, can form the high speed abradant jet to satisfy the demand of cutting oil tubing string after abrasive quickens through the nozzle of installing on the cutting head.
