摘要
介绍了光纤油井压力温度检测系统,并对下井过程中遇到的问题进行了剖析。运用该系统对胜利油田某注水井的温度、压力信息进行了实时在线测量,传感器下井井深1100 m,测得的温度值为50℃左右,压力值为16 MPa左右。描绘了油井井下温度压力信息变化曲线,为提高油田油井的采收率,了解井下信息提供了真实的数据依据。
This paper introduced an optical fiber pressure and temperature surveillance system for oil wells in detail and analyzed some problems of the process going into a well. We employed the system to perform the online real-time measurement for the pressure and temperature of a water injection oil well and obtained such data as the depth of the sensor 1100 m, temperature about 50 ℃, pressure about 16 MPa. Curves were drawn on the basis of the time-variant pressure and temperature in the well, which provided the authentic data for the improvement of the extraction rate and the knowledge of the information in an oil well.
