Abstract

Based on the Bohai oilfield, which geological condition is unconsolidated heavy oil reservoir, which is targeted to design a new 7 "high shot density big debris shaped charge. used several kinds of technology in this research ,such as numerical simulation analysis on the formation of shaped charge case debris and jet using AOTUDY and ANSYS/LS-DYNA software, and steel target test, single charge case debris collected test and 7 "perforating gun debris collected test. The experiment results show that: Numerical simulation of debris formation and jet has good consistency with ground test results. The big debris rate of new shaped charge is better than that of common ones. The most of debris lost get away from the gun aperture, which size is less than 9.53mm, most debris still stay in the perforating gun. According to the application in Bohai oilfield, the new 7 " perforator satisfied the requirements of the heavy oil gravel pack completion and multilayer injection process. After the perforation perforator debris total quality loss are less than 0.5Kg/ft., the actual drop debris mass is far less than the drop debris of the quality of 2.22Kg during the test process. The big debris forming effect is good, most of which still stay in the perforating gun, to ensure the perforating operation safety and subsequent completion process smoothly.
