近年来,原油价格日益攀升,采油率的提高也成为了测井技术备受关注的方面。光纤传感器具有耐腐蚀、耐高温的特点,还有独特的在线检测功能,因此国际上的很多石油公司格外关注光纤传感器在智能油井的应用。本文对于国际上光纤压力、温度等的在线监测还有智能系统的工程技术的发展状况和趋势进行了系统的介绍,然后简单介绍了光纤地震检波、高压高温测井等方面的发展状况。展示了利用普通光纤和耐高温光纤分别制作的压力和温度传感器的结果,还有就是利用DFB激光器声波检测的检测结果。
In recent years, the rising price of crude oil and the increase of oil recovery rate have become the areas of concern for well logging technology. Optical fiber sensor with corrosion-resistant, high temperature characteristics, as well as unique online testing capabilities, many international oil companies are particularly concerned about the optical fiber sensor in smart wells. This paper systematically introduces the development and trend of on-line monitoring of optical fiber pressure and temperature in the world, as well as the development and trend of engineering technology of intelligent system. Then it briefly introduces the development of optical fiber seismic detection and high-pressure high temperature logging. Shows the results of using pressure and temperature sensors made using ordinary fiber and high temperature fiber, and the result of using the DFB laser sonic wave detection.
