The application of high temperature resistance pressure sensor in oil & gas 

 Many industries need electronic sensing equipment that can work reliably under extreme high temperature and harsh environment, oil and gas drilling is a typical application of high temperature resistance pressure sensors. In general applications, the sensor can work stably in the range of temperature is available, but in the oil and gas drilling operations, in addition to high temperature, but also need to have explosion-proof safety certification and strong anti-vibration performance. With the deepening of drilling depth, higher requirements of temperature resistance.

New trends in the oil and gas

In the past, drilling operations have been carried out in the temperature range of 150 ° C to 175 ° C. However, the industry is beginning to drill deeper as a result of a reduction in the reserves of natural resources that can be easily drilled underground and technological advances, as well as in areas with high geothermal gradients. These harsh subsurface wells have temperatures in excess of 200 ° C and pressures in excess of 25k PSI. Active cooling is not practical in this harsh environment, and passive cooling is not effective when heating is not limited to electronic equipment.

In our country, the main drilling operation is to measure the pressure and temperature of the well by using the storage pressure gauge. First，the pressure gauge is drawn into the test depth with the test valve, then the pressure gauge is pulled out and the computer plays back the data to get the temperature and pressure data. Through this   method , there is Unable to implement monitoring data, testers can not take timely measures according to the bottom hole conditions, adjust the testing procedures. Because of the inaccuracy of data acquisition, the lack of real-time data support in testing work, the operation often occurs errors and rework. With the development of wireless technology, it is possible to monitor downhole data in real time.

New requirements for high temperature resistance pressure sensors

 At past , for high temperature pressure sensor, it needs temperature resistance up to 175 ° C, strong structure, anti-vibration, explosion-proof safety. With the deepening of the drilling depth, the temperature resistance of the sensor up to 200 ° C, even more than 200 ° C has become normal. In addition, the condition of real-time acquisition of temperature and pressure is available, and the requirements of high-temperature resistance pressure sensors to support wireless digital signals become a trend .
