Abstract
A bump detonator for the detonation in shooting of an oil well comprises a housing, a bump pin, a pin bolt, a bump pin cover, a sealing body, a sealing ring, bump ignition detonator and a base plate, the bump pin is positioned in the bump pin cover through the pin bolt, the bump pin cover is positioned in the upper chamber of the housing, the sealing body and the bump ignition detonator are both positioned on the base plate, the sealing body is installed on the upper side of the bump ignition detonator, the sealing body is provided with the sealing ring, the base plate is positioned in the lower chamber of the housing, and a sealing ring is positioned between the base plate and the housing. The bump detonator having advantages of simple structure, safe and reliable working, low cost and the like is suitable for the requirements of detonation in shooting of various oil wells with different depths, and bearing capability of the sealing body achieves 290 MPa.
Description
Technical field
The utility model belongs to the initiator technology, particularly a kind of percussion primer that is used for oil well perforation ignition usefulness.
Background technology
The perforation of China oil field use is at present ignited and is used percussion primer, no matter be single ignition structure or two structure of getting angry, pin on initiator striker or the striker interlinked mechanism, the strong shearing force that produces of well hydraulic pressure of bearing is along with the shearing force that the increase of oil well depth is suffered is increasing., adopts pin the pin of different shear strengths so will considering the difference of oil well depth in design.If adopt the pin of single shear strength, in the time of just might appearing at heavy duty service, pin is cut off the mistake perforation accident that causes in advance by the well hydraulic coupling; Perhaps the input rod is cut continuous pin and is caused the not accident of perforation when the shallow well operation.The percussion primer of the utility model design has been cancelled the unreasonable structures such as O-ring seals on the striker, make the pin on the striker no longer be subjected to the influence of the shearing force that produces by force of well hydraulic pressure, the effect of pin just makes the striker location, do not need very high shear strength, be applicable to the needs that various different depth oil well perforations are ignited.
The utility model content
The purpose of this utility model is in order to solve that pin on the existing percussion primer striker bears well liquid shearing force and the technical problem that exists, design a kind of oil well perforation simple in structure, safe and reliable and that cost is low and ignited the percussion primer of usefulness, be applicable to the needs that various different depth oil well perforations are ignited, the bearing capacity of the seal of initiator can reach 290Mpa.
The utility model comprises housing, striker, striker cover, pin, seal, sealing ring, bump ignition detonator and base etc., striker is arranged in the striker cover by pin, striker is set in the epicoele of housing, seal and bump ignition detonator all are arranged in the base, seal be contained in bump get angry detonator above, seal is provided with small sealing ring, and base is arranged in the cavity of resorption of housing, is provided with sealing ring between base and the housing.
Simple in structure, safe and reliable and low cost and other advantages that the present invention has is applicable to the needs that various different depth oil well perforations are ignited, and the bearing capacity of seal can reach 290Mpa.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Among the figure: 1 housing, 2 strikers, 3 pins, 4 striker covers, 5 seals, 6, small sealing ring, 7 sealing rings, 8 bump ignition detonators, 9 bases.
The specific embodiment
Further specify the structural concept of the present utility model and the course of work below in conjunction with example.
As shown in Figure 1, the percussion primer that a kind of oil well is used comprises housing 1, striker 2, pin 3, striker cover 4, seal 5, small sealing ring 6, sealing ring 7, bump ignition detonator 8, base 9.
The course of work of this percussion primer is: cut off pin 3 when striker 2 under the excellent hammer action of input and move downward, striker 2 puncture through seal bodies 5 and percussion bump ignition detonator 8.The detonating fuse that bump ignition detonator 8 detonates and is attached thereto.This percussion primer is the O RunddichtringO that has removed on the striker 2 with the fundamental difference of original percussion primer, design has seal 5 between striker 2 and bump ignition detonator 8, by seal 5 realize the clashing sealing of percussion blasting cap 8, the well hydraulic pressure that this seal 5 can bear 290MPa is strong, and can be pierced through by striker 2 and pull the trigger bump and get angry detonator 8 and get angry, this technical indicator is applicable to the needs that various different depth oil well perforations are ignited.
