The merits of the oil and gas well perforation fracturing link in the process of mining are directly related to oil well production and economic benefits. The dynamic pressure data in downhole of perforation process is the key data to evaluate this link. According to the well test environment and the actual signal characteristics, we developed a new type of oil well pressure gauge. This paper studied the key design in the test system, put forward feasibility schemes, and analysed the measured data, which provided a reliable research method and basis for the development of subsequent perforation fracturing products, and the accelera- tion of the perforation fracturing technology.
