摘要
目前在石油天然气勘探开发中,越来越多的钻井新工具、新工艺的应用,导致钻井速度越来越快,岩屑破碎程度越来越严重,给录井岩性识别、解释评价、层位卡取及水平井地质导向等工作带来了严峻挑战。通过对微钻时条件下的工程录井、气测录井、元素录井及随钻电测等相关参数进行深入分析,总结出适用于钻探现场地质分析的微钻时录井技术。现场实际应用表明,微钻时录井技术对于解决上述录井现场技术难题效果显著,具有一定的推广应用价值。
At present,in the exploration and development of oil and natural gas,the application of more and more new drilling tools and new technologies leads to the faster drilling speed and the fragmentation degree of cuttings which is more and more serious,which brings severe challenges to the mud logging jobs of lithology identification,interpretation and evaluation,horizon determination and horizontal well geosteering.Through in⁃depth analyses of relevant parameters such as engineering logging,gas logging,element logging and electric logging while drilling under the condition of micro⁃drilling time,the micro⁃drilling time logging technology suitable for geologic analysis of drilling site is summarized.The field application shows that the micro⁃drilling time logging technology is effective in solving the above mud logging field technical problems and has some value of popularization and application.
