井漏是钻井施工过程中最难处理的复杂情况之一,它的复杂性使它成为制约国内外石油勘探和开发的重大工程技术难题。处理井漏的关键在于确定漏层位置,能够准确判定漏层位置,将会有利于提高堵漏成功率,缩短堵漏时间,加快钻井速度。本文对国内外常用的漏层判定或测试方法进行了分析总结,并介绍了国内外新的漏层判定方法。 Lost circulation is one of the most difficult and complex situations in drilling construction, and its complexity has made it a major engineering and technical problem restricting oil exploration and development at home and abroad. The key to deal with the well leakage is to determine the position of the leakage layer, which can accurately determine the position of the leakage layer, which will be helpful to improve the success rate of plugging, shorten the plugging time and speed up the drilling. This paper analyzes and summarizes the commonly used judgment and test methods of the drain layer at home and abroad, and introduces the new judgment method of the drain layer at home and abroad.
