Method for making man-made rock core target

Abstract

The invention relates to a manufacturing method of an artificial rock core barn used for evaluation articles of an oil field oil gas water well perforator, which comprises fives procedures of screening quartz sand, manufacturing a standard test rock core, preparing an aluminium phosphate cementing agent, manufacturing the rock core by pressing and drying and sintering. The manufacturing method is easy to be implanted, the one-time success rate of quartz sand matching of different particles can be improved when a large size rock core is manufactured by the method, and the artificial rock core barn which can meet the on-site requirement and can be used in the evaluation on the perforator in high pressure seepage flow performance test is manufactured.

Description

Technical field: [0001] The invention relates to a method for making perforator evaluation supplies for oil, gas and water wells in oil fields, which belongs to the category of well logging and perforating technology. Background technique: [0002] The perforator is a special tool for the perforation operation of oil, gas and water wells in the oil field, and its performance directly affects the quality and effect of the perforation operation. At present, there are many kinds of perforating guns used in the field, and there are also many methods for evaluating their performance and quality. Usually, methods such as steel target penetration test, concrete target penetration test, and core target shooting are used. Among them, the first two can only examine the perforation hole diameter, penetration depth, burrs, etc., but cannot more realistically simulate the flow characteristics of fluid in the target perforation tunnel, while core target shooting can solve this problem.

Among them, the first two can only examine the perforation hole diameter, penetration depth, burrs, etc., but cannot realistically simulate the flow characteristics of the fluid in the target perforation tunnel, while core target shooting can solve this problem

However, the bare rock core provided by the current manufacturer is not only short in length and small in outer diameter, which cannot meet the requirements of the polymer flooding perforation test, but also cannot solve the sealing problem of the core simulated surrounding rock confining pressure during the test, and is difficult to meet the requirements of the polymer flooding perforation test.
