Abstract

The invention discloses an oil-gas well perforator ground target shooting test device, and belongs to the field of oil-gas well perforating simulation testing. The oil-gas perforator ground target shooting test device comprises a concrete target, a test sleeve, a pressure maintaining tube, a piston, a shear pin and a protective steel plate. According to the invention, a high temperature and high pressure liquid is pumped into a test sleeve through a pressure testing pump so as to simulate an underground high temperature and high pressure environment, the pressure maintaining tube is internally provided with the piston, the shear pin penetrates through the pressure maintaining tube along the radial direction of the pressure maintaining tube and is inserted into the piston, the pressure in the pressure maintaining tube is released by using the shear pin, and the pressure release delays relative to secondary energy release of a perforator in time, so that the test sleeve is enabled to still maintain the simulated underground high temperature and high pressure state in the process of secondary energy release performed by the perforator, thus the process of performing perforation by the perforator in the underground environment is simulated, and the reliability of evaluation performed on the safety and the perforating effect of the perforator according to the target shooting test is ensured to be high.

Description

technical field [0001] The invention relates to the field of oil and gas well perforation simulation testing, in particular to a ground target shooting test device for an oil and gas well perforator. Background technique [0002] Perforation operation is a very important link in oil and gas exploration and development. By running a perforator into the casing, the perforator fires perforating bullets at a certain phase angle in the radial direction, and the perforating bullets penetrate the casing and the cement sheath. And injected into the oil well formation, so that the inside of the casing is connected with the oil well formation, the crude oil flows into the casing through the injected hole, and the perforating bullet injected into the formation can improve the permeability of the formation. In order to determine whether it is safe to use a certain perforator for perforation and whether the perforation effect can meet the needs of oil well development, the perforator nee...
