Research Of The Underground Temperature And Pressure Measuring System Based On Wireless Technology

Aiming at the complex of in-well environment, strong factors such as high temperature, high pressure, this paper puts forward a set of STM32processor and wireless technology, the downhole temperature and pressure measuring system. This measurement system based on STM32CPU, combined with the simulated measurement circuit, measuring the temperature and pressure on the oil Wells. Through downhole data collector of downhole temperature and pressure measurement, inoue distance recorder to record of depth, can realize precise measurement of the oil well different depth corresponding pressure and temperature, the whole measurement process and data transmission can be directly through the handheld device and wireless communication operation, convenient operation, low requirement to the work environment, at the end of the measurement of downhole data collector and inoue distance recorder to transmit their data through wireless module to hold control equipment, and is controlled by a handheld device for data integration and selection, through the USB. interface to transmit data to PC, the measured results on the upper machine is displayed in the form of charts and curves. Clear visual effect, trend obviously, is suitable for qualitative and quantitative analysis.The research work of downhole temperature, pressure arid so on many parameters measurement system development has the certain instruction meaning and reference value.
