Abstract
The utility model relates to a perforator used test of simulating underground perforating condition of mine. The technical proposal of the utility model is that a simulating gun is plugged at lower part of a connecting body; the upper part of the simulating gun is provided with a perforating bullet whose upper part is provided with a bullet fixer; outer wall at the upper part of the bullet fixer is inserted in the connecting body by a bullet seat; a central hole of the bullet fixer is internally and orderly provided with a detonator, an explosive fuse and another detonator. The utility model is characterized in that the bullet fixer is simple in structure with adjustable length; a butting method of explosion propagation is adopted so as to guarantee the once success rate of perforating test, beneficial for the correspondence of the experiment parameter; changing of different bullet seats can satisfy the experiment conditions of high inner explosion and high outer explosion needed by the perforating bullets with any type.
Description
One, technical field
The utility model relates to a kind of perforation laboratory apparatus, specifically is applied to the experiment perforator of simulation well perforation experiment.
Two, background technology
Perforating job is an important link of oil-gas exploration and exploitation, and effectively preforation tunnel is vital for correct evaluation oil-gas Layer, raising oil gas well production and raising oil-gas reservoir recovery percent of reserves.The quality of perforation system and perforating bullet is to improve the prerequisite of perforating quality, therefore, how correctly to estimate the quality of perforator, improves perforating effectiveness and becomes the domestic and international research emphasis.
At present, the experiment of perforator and detection are rested on ground beat steel target and concrete target, when playing the steel target, perforating bullet is exposed outside, and the serious distortion of the distance between bullet and the target body (height of burst), can not reflect the actual usefulness of perforating bullet fully.
Three, utility model content
The purpose of this utility model is exactly the defective that exists at prior art, and the experiment perforator of perforating condition under a kind of convenient and practical simulation well is provided.
Its technical scheme is: in the shutoff of the bottom of connector model gun is arranged, model gun top is provided with perforating bullet, perforating bullet top is provided with solid body, is contained in the connector Gu the body external wall of upper portion plays cover for seat, is penetrated with detonating primer, detonating fuse, detonating primer successively in the centre bore of solid body.
Characteristics of the present utility model are: (1) solid body structure is simple, and adjustable length, can satisfy the secure fixation of any model perforating bullet.Gu the centre bore on the body assembly as the chamber of placing the propagation of explosion assembly, has fixing and centralizing function to the propagation of explosion assembly.(2) adopt butt joint propagation of explosion mode, perforating bullet has been exported the higher energy that detonates, guaranteed the one-time success rate of perforation experiment, help the uniformity of experiment parameter.(3) only need to change different bullet seats and just can satisfy test conditionss such as the required interior height of burst of the perforating bullet of any model, the outer height of burst.
Four, description of drawings
Accompanying drawing is a sectional structure chart of the present utility model.
Five, the specific embodiment
With reference to the accompanying drawings the technical program is described further.
The design of experiment perforation target: with reference to the requirement in the perforator evaluation method of API recommendation, the evaluation of perforator is tired out the sandstone target with shellfish under the stress condition, because the sandstone target has good homogenieity and stable intensity, biggest advantage is that it wears the actual conditions of dark data near down-hole formation, has improved the practicality of experimental study greatly.
The experiment perforator mainly is made up of detonating primer 1, detonating fuse 2, solid body 3, perforating bullet 4, model gun 5, bullet seat 12, connector 13 etc.In the shutoff of the bottom of connector 13 (being threaded) model gun 5 is arranged, and increased sealing ring 6 at connection of thread.Model gun 5 tops are provided with perforating bullet 4, and perforating bullet 4 tops are provided with solid body 3, Gu body 3 external wall of upper portion are sleeved in the connector 13 by bullet seat 12, are penetrated with detonating primer 1, detonating fuse 2, detonating primer 1 successively in the centre bore of solid body 3.For the ease of being connected, be provided with flange 14 on the top of model gun 5 with experiment perforation target.Connector 13 tops are connected (not drawing among the figure) by internal thread with safe big gun head external screw thread.Gu body 3 is mainly used to fixedly perforating bullet 4 with bullet seat 12.Detonating primer 1, detonating fuse 2 are used for detonating of perforating bullet 3.Model gun 5 has been simulated existing wall thickness, interior height of burst condition with perforator fully, improves the objective evaluation to perforating bullet.This experimental rig has been simulated the virtual condition of perforating gun in the down-hole fully, and model gun 5 can be adjusted wall thickness, the height of burst according to used perforating gun.
Claims (2)
1. the experiment perforator of perforating condition under the simulation well, the structure that it is characterized in that this experiment perforator is: in the shutoff of the bottom of tubular connector model gun is arranged, model gun top is provided with perforating bullet, perforating bullet top is provided with solid body, Gu the body external wall of upper portion is played cover for seat and is contained in the connector, in the centre bore of solid body, be penetrated with detonating primer, detonating fuse, detonating primer successively.
2. the experiment perforator of perforating condition under the simulation well according to claim 1 is characterized in that: be provided with sealing ring at connector and model gun joint portion, be provided with flange at the periphery of model gun.
