油气井井下检测技术进展综述

Summary of progress in downhole detection technology for oil and gas wells

随着油气资源开发的深入发展,油气资源开发也变得越来越标准化、智能化。在工程技术的实际应用中,特别是在井下作业中,温度、压力等参数的实时变化反应了油气井的工作状况。因此井下对温度和压力进行高精度的测量,对于确定油层的位置、油层的厚度、含水层的深度,及明确注水层的深度等井下作业重点工程要素都具有着重要的意义。本文综述了近年来国内外油气井井下检测技术的进展情况。主要包括存储式、井下测试数据地面直读技术、光纤探测技术等。并在最后简要分析了未来井下检测技术发展的方向。

With the in-depth development of oil and gas resources exploitation,oil and gas resources exploitation has become more standardized and intelligent.In the practical application of engineering technology,especially in downhole operations,real-time changes in parameters such as temperature and pressure reflect the working conditions of oil and gas wells.Therefore,the high precision meas-urement of temperature and pressure in the underground has important significance for determining the location of the oil layer,the thickness of the oil layer,the depth of the aquifer,and the depth of the water injection layer.This paper reviews the progress of downhole detection technology for oil and gas wells at home and abroad in recent years.It mainly includes storage type,downhole test data ground direct reading technology,and fiber detection technology.Finally,the direction of future development of downhole detection technology is briefly analyzed.
