Description
Technical field
The present invention relates to a kind of unfreezing breakouting pack of dynamite method and apparatus of processing for oil gas well drilling engineering accidents such as extended reach well, horizontal wells.
Background technology
Conventional lock of tool drilling often adopts the quick-fried mode processing accident released of leading, and major part is to adopt instrument cab, the deadweight of dependence instrument, the soft method of sending of cable, lead quick-fried releasing after conveying puts in place, but when processing large displacement, horizontal well lock of tool drilling, if adopt conventional method to be lowered to by pumping and instrument deadweight, can not overcome pipe frictional force at large gradient, horizontal segment, detonating fuse usually can't be transported to precalculated position, causes well to be scrapped.
Summary of the invention
The purpose of this invention is to provide a kind of extended reach well, horizontal well unfreezing breakouting pack of dynamite new method, carrying method by the soft or hard combination, be applied in large displacement, horizontal well lock of tool drilling releasing processing, overcome due to the pipe frictional force produced in horizontal well, detonating fuse is accurately sent into to precalculated position, realize breakouting pack of dynamite accurately, remove in time lock of tool drilling, make accident treatment become simple.
A kind of extended reach well of the present invention, horizontal well unfreezing breakouting pack of dynamite new method, mainly to connect bunchiness by breakouting pack of dynamite device, location instrument, special transfer device, this tool string of going into the well is for being rigidly connected, can once the breakouting pack of dynamite device be transported to the stuck point position, ground is connected with the cable instrument cab, realizes quick-fried releasing.
The difference that new method of the present invention and conventional method are main: new method of the present invention has adopted the special-purpose unfreezing conveying device of class rigidity, can disposable conveying fall quick-fried device to precalculated position, be not subject to hole deviation, the impact in orientation, and the normal cable carrying method is only applicable to the borehole condition that hole deviation is less than 45 degree left and right, the unfreezing that is not suitable for large gradient, extended reach well is processed, main cause is to carry down quick-fried device to precalculated position, usually causes filling out a sidetracking or scrapping.
A kind of extended reach well of the present invention, horizontal well unfreezing breakouting pack of dynamite equipment are to connect string, breakouting pack of dynamite instrument and auxiliary equipment by special transfer device to form; Auxiliary equipment consists of cable, cable Instrumentation Engineering car and pulley; Cable is arranged in land cable Instrumentation Engineering car, and cable is connected the string upper end and connects with special transfer device by pulley; Special transfer device connects the string lower end and is connected with the breakouting pack of dynamite instrument; The breakouting pack of dynamite instrument is in series by magnetic orientation instrument, safe explosion joint, detonating fuse successively; The breakouting pack of dynamite instrument is placed in drilling rod;
It is to be connected and be connected in series from beginning to end by a plurality of conveying devices that special transfer device connects string; Conveying device consists of copper cable socket A, bakelite sheath A, " O " type rubber ring, two male joint, copper connecting rod, copper adapter sleeve, copper cable connector, bakelite sheath B, copper cable grip, rubber sheath, body, high temperature resistance flexible cable line, copper cable plug B; Body is cylindrical tube, and two two male joints two ends are provided with external screw thread, with body two ends internal thread, are connected respectively, by the seal with elastometic washer of " O " type; Copper cable socket A and copper cable plug B are arranged in two male joints, with copper connecting rod, copper adapter sleeve, copper cable connector, copper cable grip, high temperature resistance flexible cable line, be connected successively, bakelite sheath A, bakelite sheath B are connected successively with rubber sheath; The two male joint inwalls of bakelite sheath A ring arrange; Bakelite sheath B and rubber sheath ring inner body wall arrange.
Fixed block, with the drilling tool of well head, the cylinder of cable Instrumentation Engineering car, remain on a work plane, cable is caused to well head by pulley, and the special transfer device that will be connected with cable connects string and the breakouting pack of dynamite instrument is slowly sent in tubing string, connects conveying lever, according to releasing a little of determining, deliver to assigned address, arrive and to release a little, confirm errorless after, be applied with suitable reaction torque, (movement) lighted a fire, released.
The special transfer device that the present invention adopts connects the bindiny mechanism that string is the gentle combination of a kind of steel, can disposable the breakouting pack of dynamite instrument be transported to precalculated position, be not subject to hole deviation, the impact in orientation, can bear certain axial compression, can overcome the frictional resistance of pipe at horizontal segment, by arriving precalculated position under destructor, changed former cause cable transfer shortcoming not in place, remove in time lock of tool drilling, save production cost, shorten break down time.
