This paper aims to evaluate the performance of the integrated composite perforation system in tight reservoirs. To simulate complex pressure conditions of the reservoir, a perforation test device was developed in accordance with API RP 19B sections 4.2 and 4.4 procedures, and a set of test evaluation methods was designed. Using a type 4-1/2in perforating charge and pre-propellant charge, a tight sandstone target with rock physical characteristics similar to the real reservoir were selected for the perforation test under simulated reservoir pressure, pore pressure, and wellbore pressure. The characterization of the perforation tunnel and fracture morphology using CT scanning and thin-section analysis techniques. The results show that under the simulated reservoir pressure conditions, the integrated composite perforation system reduces the penetration depth by nearly 8% compared with the conventional perforation, improves the average flow efficiency by 17.2%, and creates multiple 40mm-100mm extended fractures at the end of the tunnel, the perforation and fracture enhancement is improved by an average of 1.34 times.
