光纤传感器在延长油田的应用研究

The Applied Research of Optical Fiber Sensor in Yanchang Oilfield

石油测井是石油勘探开发的重要环节,延长油田所辖油区地层特殊,传统测井手段易出现漏层,测量项目数据精确度不够。详细分析了光纤传感器工作原理,推导其在石油测井项目解析表达式,由此采用光纤传感器设计光纤传感系统,实验结果表明系统测井数据准确,能够很好地满足油井井下测井的需要。

Oil well logging is an important link of petroleum exploration and development of oil field.The traditional logging methods will appear leakage and the inaccurately data because of the special stratum in yanchang oilfiled.This paper analyzed the optical fiber sensor principle,the analytical expressions in oil well logging,which adopts project design of optical fiber sensing system,optical fiber sensors,the experimental results show that the system log data accuracy,can well meet the needs of oil well logging.
