The Influence Of The Concrete Target Strength Of Perforating Gun Perforation Depth

Charge through the concrete target test is to evaluate the charge perforation performance is one of important means,in the process of test,the target body strength of perforating charge perforation performance will produce great influence,which affect the inspection result.By the differences of the intensity of ten target body and there were no differences in evaluation results of effective corrective force method.In this paper,we study together can gun through the concrete ground target(according to GB/T 20488-20488 "the oil and gas Wells can gather perforating equipment performance test method" made of concrete target)perforating target body when testing compressive strength of perforating gun perforation depth,the influence of the target body compressive strength is given for the degree of the influence of perforation depth,and a reasonable evaluation method is given.Calculate the concrete target,block compressive strength;Using testing compressive strength of block,pressure testing machine,research the relationship between the strength of the two methods of testing.Numerical simulation of two kinds of shaped gun perforation depth,and the test result is to check the accuracy of the theoretical calculation results,and then establish a shaped gun perforation and strength of relationship(curve);By test to establish two shaped gun perforation and strength to verify the relationship between theory study law(curve)is correct.Use of other domestic manufacturers can gather perforator test results for correction of the punch and intensity curve.Strength is given to the influence of perforation depth correction methods.
