Abstract
The utility model provides a well explosion shaper device suitable for the deep well environment, including a detonator, an explosion propagation device and a shaper case, in which the explosion propagation device is cylinder-shaped, with the external-threaded end coaxially connected to the detonator and the internal-threaded end eccentrically connected to the shaper case; the explosion propagation device contains a propagation powder chamber on the end corresponding to the detonator, and the propagation powder chamber communicates with the eccentric shaper case. Because the detonator and the shaper case are eccentrically connected with each other, the propagation pellet will not move under the high pressure of the deep well environment, so that any deformation against the oil well casing can be precisely repaired. The utility model is suitable to repair or shape any deformation against the oil well casing in the deep well environment. Also all the joints are sealed with high-temperature resistant rubber rings, which satisfies the tightness requirement of the well explosion shaper device in the deep well environment.
Description
Technical field
The utility model relates to a kind of repair outfit that is used for the well wellbore sleeve pipe---and pit shaft explosive shaping device relates in particular to a kind of pit shaft explosive shaping device that is applicable to deep-well.
Background technology
Explosive shaping is widely used in the reparation of oil well damage sleeve pipe.Because the oil gas well is dark more, the environment stress of depths, down-hole and temperature are just high more, and be also just high more to the requirement of construct the high temperature resistant, withstand voltage of equipment and sealing.Chinese patent ZL00237484.6 and ZL00237485.4 disclose two kinds of explosive shaping devices respectively, but these explosive shaping devices since booster gains with the coaxial setting of main body powder column or directly be connected, cause booster gains under the high pressure of deep-well environment, high temperature action, to move up, thereby can not repair deformation place exactly, so be not suitable in deep-well, using to oil well casing.
Summary of the invention
The purpose of this utility model is to provide a kind of pit shaft explosive shaping device that is applicable to deep-well.
Deep-well mineshaft explosive shaping device of the present utility model comprises initiator, propagation of explosion device and shaping cartridge case, and wherein the propagation of explosion device is cylindric, and the one end is connected so that external screw thread and initiator are coaxial, and the other end is connected with shaping cartridge case core shift with internal thread; An end of corresponding initiator is provided with the propagation of explosion coyote hole that is communicated with described core shift shaping cartridge case in the propagation of explosion device, the indoor booster explosive that is equipped with of this booster explosive.
This propagation of explosion coyote hole is communicated with described core shift shaping cartridge case.
In order to satisfy of the requirement of deep hole shooting apparatus for shaping, be respectively equipped with the high-temperature resistant rubber sealing ring in the junction of propagation of explosion device and initiator and shaping cartridge case to sealing performance.
For the ease of installing, use, one side be provided with the connection carriage at the relative shaping cartridge case of propagation of explosion device.
The utility model has the following advantages compared with the prior art:
1, initiator of the present utility model is connected with explosive shaping cartridge case core shift, it is mobile that booster gains can not produced under the high pressure of deep-well environment, thereby can repair deformation place exactly, be applicable to of reparation, the shaping of deep-well environment the oil well casing deformation place to oil well casing.
2, each connecting portion of the present utility model all adopts the sealing of high-temperature resistant rubber circle, has satisfied the requirement of deep hole shooting apparatus for shaping to sealing performance.
3, the utility model is simple in structure, cost is low, installs, uses all very convenient.
Description of drawings
Fig. 1 is a structural representation of the present utility model
The specific embodiment
A kind of device that is used for the deep-well mineshaft explosive shaping comprises initiator, propagation of explosion device and shaping cartridge case.With reference to Fig. 1, propagation of explosion device 1 is cylindric, and the one end is with external screw thread and coaxial connection of initiator (not drawing among the figure), and its other end is connected with shaping cartridge case 3 core shifts with internal thread.Junction at propagation of explosion device 1 and initiator and eccentric shaping cartridge case 3 is respectively equipped with the high-temperature resistant rubber sealing ring.An end of corresponding initiator is provided with the propagation of explosion coyote hole 2 that is communicated with described core shift shaping cartridge case 3 in the propagation of explosion device 1, and this propagation of explosion coyote hole 2 is built-in with booster explosive.
For the ease of installing, using, an end of the corresponding core shift shaping of propagation of explosion device cartridge case is made taper shape, one side and connect carriage 4 being provided with of the eccentric relatively shaping cartridge case 3 of propagation of explosion device.
Excite booster explosive in the deep hole shooting apparatus for shaping propagation of explosion coyote hole from the explosion energy of initiator, the explosion energy of booster explosive excites the shaping cartridge case, reaches the purpose of repairing oil/gas well damage sleeve pipe.
