摘要
气测录井技术是发现油气的关键技术手段,被广泛应用于油气勘探开发中。鄂恩地2井作为一口小口径页岩气地质调查井,其钻机结构和钻探方式与常规的油气开发井区别较大。简要介绍小口径钻探气测录井施工的原理、操作步骤、解释原则、气测录井施工过程中遇到的问题及其解决办法,参照气测录井结果和施工过程中积累的经验,分析在施工过程中影响气测录井数据准确性和录井曲线连续性的主要因素,探索小口径页岩气地质调查井气测录井操作规程。
Gas logging technology is the key technical means to discover oil and gas,which is widely used in oil and gas exploration and development.Well Eendi-2 is a small diameter geological survey well of shale gas,its drilling equipment and drilling mode is different from development well.The paper briefly introduces the construction principle,operation steps,interpretive principle and the problems encountered in logging construction and their solutions of gas logging in small diameter drilling.According to the results of gas logging and the experience accumulated in the construction process,the main factors affecting the accuracy of gas logging data and the continuity of logging curves are analyzed,and the operation rules of gas logging in small diameter shale gas geological survey wells are explored.
