Abstract

A petroleum reservoir casing perforation anti-collapse simulation test method and a simulation tester are applied to a ground test of petroleum down-hole reservoir casing perforation after anti-collapse performance. The simulation tester is characterized in that a pressure cylinder is cylindrical. The wall of the pressure cylinder is fixed with a hydraulic sensor and a high pressure catheter. Twoends of the pressure cylinder are respectively fixed with plugging flanges. The central holes of the plugging flanges are fixed with plugs. The whole test process of the test method includes preparation of reservoir casing used for test, metal plugging of simulation holes, plugging of two ends of the reservoir casing used for test, installation and pressure test. The effect is that the petroleum down-hole reservoir casing perforation after anti-collapse test of the invention can be finished on the ground. Anti-collapse performance after the reservoir casing perforation can be obtained. Oil andgas field operation parameters are optimized. The safety of a string structure and the production safety of the petroleum well are guaranteed. The invention is applied to indoor installation and computer control. And the anti-collapse performance after the reservoir casing perforation is convenient to be obtained.

Description

technical field [0001] The present invention relates to the technical field of petroleum drilling and well completion, in particular to a ground test method for the performance of an oil layer casing after perforation in an oil well, specifically a method for anti-collapse simulation test of an oil layer casing after perforation, which belongs to an oil layer Casing destructive testing. Background technique [0002] At present, oil and gas wells use oil layer casings in well cementing and completion, and the oil and gas in the formation oil reservoir can pass through the oil layer casings and flow into the casings through perforation of the oil layer casings. However, when explosive perforation is carried out on the casing in the oil layer, the anti-extrusion (collapse) ability of the casing in the oil layer decreases. Insufficient, the casing shrinkage deformation often occurs in the perforation section of the oil layer, that is, collapse failure. In order to accurately u...
