Description
One, technical field:
The utility model relates to a kind of petroleum industry perforating technology, particularly a kind of oil tube conveying gun perforation linear electric generator.
Two, background technology:
Both at home and abroad the oil tube conveying gun perforation mode that generally adopts caber or the add hydraulic pressure priming system that causes perforator detonates, and realizes the perforation purpose.Oil pipe in the past (drilling rod) conveying gun perforation initiator has mechanical impacting type initiator, pressure excitation type initiator, delayed type pressure detonator several.Mechanical impact formula initiator, it is several to be divided into sand control initiator, economic benefits and social benefits initiator, sealed type initiator etc.All be to utilize the metal bar kinetic energy that free fall produces in oil pipe, promote the striker of bottom initiator, piston is glided, percussion cap (detonator, initiator) is detonated, thereby finishes perforation.Its drawback is because foreign material too much or in the oil shake out seriously, is accumulated in the initiator top, makes metal bar can't fall to clashing into firer's part, can not realize perforation; For the serious well that shakes out, sand grains buries initiator, and metal bar is buried when falling together, when salvaging,, play oil pipe in the time-delay in case salvage failure, in playing the oil pipe process, because oil pipe vibrations or percussion drill, sand grains reduces gradually, and metal bar is descending, and then ignition perforator, cause the blast of mistake perforation or well head, cause the certain economic loss, workmen's personal safety also can't guarantee.Another mode that adds hydraulic pressure can be applicable to several initiators such as economic benefits and social benefits formula initiator, the compound initiator of perforating, gun breech pressure detonator.Be to utilize the well hydraulic coupling to promote piston, cut off safety pin, piston continues to lower slider, drives striker, cuts off safety pin, and striker moves downward percussion cap, and igniter cap is got angry and ignited perforator, realizes perforation.Its drawback is that available initiator kind is many, and firer's part model of use is many, easily causes confusion; The structure more complicated, separate storage during transportation easily causes the assembling error during construction, cause and can't detonate; Normal temperature and high temperature initiator external form are difficult for differentiating, and the pin designs force value is different, are unfavorable for providing, in case provide mistake, cause the mistake perforation easily; During according to the well depth setup pressure value, the easy landing of the pin of initiator is difficult for discovering, in case be used for construction, causes uncertain consequence; During this type of initiator assembling, firer's part is relatively more responsive, in case go wrong, can cause personnel's injures and deaths in ground burst.The delayed type pressure detonator is on the basis of common initiator, has increased by a time-delay tube and an accessory.In the time of detonator detonates, ignite and go up ignitron, the delay powder burning delay time after 5-10 minutes, the down-firing pipe was ignited again, and the down-firing pipe ignites ignition charge, and ignition charge is cap sensitive, thereby excited the propagation of explosion device, ignited perforator, the realization perforation.Its drawback is consistent with the drawback of pressure excitation type initiator.
In sum: priming system quantity and kind that produce to use are many, and the cost height particularly is subjected to factor effects such as well site stray electrical current, radio-frequency current, electric leakage, misoperation during the cable conveying gun perforation, makes workmen's security risk increase.
