Abstract
The utility model relates to a perforation technology in the oil industry, in particular relates to an interlayer supercharging device of oil delivery perforation. The interlayer supercharging device of oil delivery perforation has the technical scheme that a piston rod, a supercharging head and an interlayer gun are included, wherein the upper end of the interlayer gun is movably connected with a perforation gun at the next higher level, and the lower end is movably connected with a linear generator; one end of the piston rod is tightly connected with the perforation gun at the next higher level, and the other end is connected with the supercharging head; a plurality of through holes communicated with the outside are arranged on the interlayer gun, and the size of the through holes ensures that the perforation gun in a falling process can be fully filled with liquid. The utility model has the advantages that fluid column pressure generated by the directional discharge of detonation pressure in a perforator at a former level is utilized to drive the linear generator which generates electricity energy so as to safely ignite the initiation of a perforator at the next level and achieve the aim of the perforation, thereby decreasing the use of initiating explosive devices and eliminating the hidden danger.
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 interlayer supercharging device.
Two, background technology:
The oil tube conveying gun perforation supercharging device generally utilizes the principle of the quick-fried production deposits yields of priming system pressure both at home and abroad, and realize that the next stage perforator detonates, in interlayer supercharging device inside gunpowder is housed, rely on the detonation energy of higher level's perforator to excite powder burning, produce gases at high pressure, pass to the next stage perforator by the body of a gun or oil pipe, reach the purpose of the following oil reservoir perforation of interlayer.The problem of its existence is: use the quantity and the kind of priming system more, gunpowder, detonator, propagation squib, firer's cap etc. are roughly arranged; Volume is bigger, and transportation stores inconvenient; When interbed length is long, cause the transmission energy to reduce easily; When interlayer was too much, the initiator of use was more, and constructing operation is loaded down with trivial details, increased accident potential and constructor's unsafe factor.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of oil tube conveying gun perforation interlayer supercharging device of simple in structure, safe and reliable, low cost of manufacture is provided.
Its technical scheme is: comprise piston rod, pressurization head and interlayer gun, the upper end of interlayer gun is by flexibly connecting with the upper level perforating gun, the lower end is by flexibly connecting with linear electric generator, one end of piston rod closely is connected with the upper level perforating gun, the other end is connected with pressurization head, interlayer gun is provided with a plurality of through holes that are in communication with the outside, and hole size can guarantee that interlayer gun fully charges into liquid in transferring process.
Wherein, an end of described piston rod closely is connected with the upper level perforating gun by sealing ring, its good seal, and it is good to slide, and under the effect of upper level detonation pressure power, transmits pressure by promoting the fluid column of pressurization head in interlayer gun.
The beneficial effects of the utility model are: utilize the detonation pressure orientation in the previous stage perforator to release, the head of liquid that produces promotes linear electric generator, produces electric energy safe detonation next stage perforator and detonates, and reaches the purpose of perforation, reduce the use of priming system, removed potential safety hazard.
Four, description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Among the last figure: piston rod 1, pressurization head 2, interlayer gun 3, through hole 4 and sealing ring 5.
Five, the specific embodiment:
In conjunction with the accompanying drawings 1, the utility model will be further described:
Its technical scheme is: comprise piston rod 1, pressurization head 2 and interlayer gun 3, the upper end of interlayer gun 3 is by flexibly connecting with the upper level perforating gun, the lower end is by flexibly connecting with linear electric generator, one end of piston rod 1 closely is connected with the upper level perforating gun by sealing ring 5, the other end is connected with pressurization head 3, and interlayer gun 3 is provided with a plurality of through holes that are in communication with the outside 4.
Its operating principle is: utilize detonation pressure orientation in the one-level perforator to release in the interlayer gun and enlarge and impact the lifting surface area that loads, reliably start the linear electric generator operation, guarantee that the electric energy that produces ignites the next stage perforator, realize the purpose of perforation.
The course of work is as follows: when perforator arrives target zone, utilize caber formula power supply, voltage-controlled break-make device and voltage-controlled initiator are connected, ignite the one-level perforator, the pressure of the quick-fried production deposits yields of one-level perforator sends piston rod to, and piston rod promotes pressurization head and glides, make the fluid column in the interlayer gun produce enough big pressure, this pressure promotes linear electric generator motion generating, and the next stage perforator is ignited, and reaches the purpose of the following oil reservoir perforation of interlayer.
