Abstract:

In the process of perforating will produce two kinds of pressure pulses. in the design of shock resistance ,sensor selection and sensor frequency response , the first pulse is an important parameter. the second pulse is an important parameter of petroleum enterprise engineering analysis. To measure the first pulse in high temperature ,high pressure , and high impact, provide important design basis for the pressure measurement system, promote the service life of Perforation gun internal pressure testing system and reduce the high cost of signal collecting, full guarantee the dynamic testing precision, this article embarks from the actual application requirements, the overall design scheme of frequency response bandwidth and the technical index of the test signal are presented.
