| Abstract: | A sensor for the measurement of downhole temperature and pressure is designed.It uses the fiber bragg grating measuring principle.An especial package structure is designed for it.The sensor is of the pressure measuring range of 0～50 MPa and the pressure measuring accuracy of 0.1%,and the temperature measuring range of 0～150 ℃ and the pressure measuring accuracy of 0.5 ℃.It has also good stability and suits for downhole permanent monitoring.If it matches with separate layer testing tool,it can finish the separate-layer multi-point monitoring of temperature and pressure for rod pump and electric pump oil wells. |
