Reasonable control and design of peak pressure is a prerequisite for the use of high-energy gas fracturing technology in oil wells. Accurately measuring the peak pressure is the primary task of this technology. Copper pillar pressure measurement is different from the P-t tester, with simple structure, convenient and intuitive is widely used in the determination of peak pressure in high-energy gas fracturing. The design of a new copper column pressure gauge - ultra-high pressure oil is not immersed in the pressure sensor, with a reliable sealing device to ensure the normal copper column compression, the measured value obtained high success rate, high accuracy and low cost, The factors that affect the peak pressure are analyzed, and the method to deal with the value of pressure measurement and the problems to be noticed are put forward to improve the accuracy of the peak pressure. The application results of the new type of copper pillar potentiometer are analyzed. The value is credible, providing an important parameter basis for the research of this technology.
