The utility model has the advantages that the pressure of well liquid and the elasticity of the spring are utilized to switch on or off the conductive plug and the voltage-controlled blaster at the lower part so as to further realize the aim of perforation, can prevent a non-blast gun perforator from accidentally exposing on the ground, and can ensure the safety of constructors on the ground.
Description
One, technical field:
The utility model relates to a kind of petroleum industry perforating technology, the voltage-controlled break-make device of particularly a kind of oil tube conveying gun perforation.
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 perforating gun 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 initiator etc.All be to utilize the metal bar kinetic energy that free-falling 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, constructor'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, maloperation during the cable conveying gun perforation, makes constructor's security risk increase.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, provides a kind of simple in structure, more safe and reliable oil tube conveying gun perforation voltage-controlled break-make device.
Its technical scheme is: comprise conductive plug, piston, spring, felt pad, voltage-controlled initiator and perforating gun, voltage-controlled initiator is housed in the perforating gun, be provided with conductive plug, piston, spring and felt pad in the upper end cavity of voltage-controlled initiator, conductive plug is by felt pad and perforating gun insulation, spring is housed in the piston, spring one end withstands on the inwall of piston, and the other end withstands on the step of perforating gun.
Above-mentioned conductive plug is the triangular type, can guarantee abundant conducting.
Be provided with sealing ring between the above-mentioned piston and the inwall of perforating gun.
The beneficial effects of the utility model are: the elastic force that utilizes well hydraulic coupling and spring, the voltage-controlled initiator of conductive plug and bottom is switched on or switched off, and then realizing the purpose of perforation, ground construction personnel's safety is guaranteed in the blast that meets accident on ground of the perforator that can avoid not detonating.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Among the last figure: conductive plug 1, piston 2, spring 3, felt pad 4, voltage-controlled initiator 5 and perforating gun 6.
Five, the specific embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described:
Its technical scheme is: comprise conductive plug 1, piston 2, spring 3, felt pad 4, voltage-controlled initiator 5 and perforating gun 6, voltage-controlled initiator 5 is housed in the perforating gun 6, be provided with conductive plug 1 in the upper end cavity of voltage-controlled initiator, piston 2, spring 3 and felt pad 4, conductive plug 1 is by felt pad 4 and perforating gun insulation, spring 3 is housed in the piston 2, spring 3 one ends withstand on the inwall of piston 2, the other end withstands on the step of perforating gun 6, utilize the elastic force of well hydraulic coupling and spring, the voltage-controlled initiator 5 of conductive plug and bottom is switched on or switched off, and then the purpose of realization perforation, oil pipe be can be applied to and (TCP) and cable conveying gun perforation technology carried.
Above-mentioned conductive plug 1 is the triangular type, can guarantee abundant conducting, is provided with sealing ring between the inwall of piston 2 and perforating gun 6.
Its operating principle and process are as follows: perforator is transferred to after the interior certain depth of oil pipe, under the effect of well hydraulic coupling, piston drives conductive plug to lower slider, conductive plug and voltage-controlled initiator are connected, when the power bar of being thrown in by well head arrives when setting layer position and the conductive plug connection, power supply begins to ignite perforator to voltage-controlled initiator power supply.After carrying on perforation finishes perforator, ambient pressure is during less than setting pressure, and under the elastic force effect of spring, conductive plug separates with voltage-controlled initiator, and ground construction personnel's safety is guaranteed in the blast that meets accident on ground of the perforator that can avoid like this not detonating.
