特殊录井技术在川渝页岩气地质导向与储层评价中的应用
摘要
Abstract
In shale gas exploration and development,precise geosteering and reservoir evaluation are crucial for enhancing extraction efficiency.This study aims to improve formation classification accuracy and reservoir mineral composition analysis by refining specialized logging techniques through sensitive elements.By integrating X-ray fluorescence(XRF)element logging and natural gamma spectroscopy logging while drilling(LWD),combined with curve crossplot and chart methods,we achieved precise formation division and scientific interpretation of reservoir parameters.Field tests demonstrated 100%accuracy in horizon identification and a 92.5%consistency rate in real-time interpretation,effectively supporting geosteering and resolving the ambiguity of single-gamma steering.The results provide critical data support for subsequent fracturing layer selection,enhance logging precision,and offer technical support for shale gas exploration and development in the Sichuan-Chongqing region and nationwide.关键词
