The capillary pressure monitoring system of which the main controller is PIC16F877 MCU is described, the system used inert gas as pressure transfer medium, completed the measurement of wellhead gas pressure in the ground, then calculated the pressure of certain depth according to the pressure in the wellhead. The system design principle and realization of software and hardware are introduced, the whole system includes data collection, data processing, data storage and data display and so on. Through laboratory and field tests prove that the pressure monitoring system with high precision, high efficiency, good stability, strong real time, etc, which can meet measurement scene environmental requirements.
