地层评价与测井技术新进展:第66届SPWLA年会综述OA

This paper provides a brief overview of the key points of the 66th annual logging symposium of the Society of Petrophysicists and Well Log Analysts(SPWLA).Based on the 141 academic papers exchanged at the conference,the latest research progress in logging technology is summarized and analyzed from four aspects,formation evaluation technology and its application,electromagnetic logging technology and its application,acoustic logging technology and its application,and nuclear logging technology and its application.Research indicates that well logging technology is rapidly evolving toward greater intelligence,precision,and environmental sustainability.Formation evaluation,integrating digital rock technology with artificial intelligence(AI),has evolved from macroscopic qualitative analysis to microscopic quantitative characterization,significantly improving the accuracy of complex reservoir assessment.Electromagnetic logging has achieved breakthroughs in ultra-deep penetration and high-resolution imaging,supporting precise geological steering and detailed reservoir evaluation.Meanwhile,acoustic and nuclear logging technologies,empowered by advanced data processing algorithms and novel sensors,have made significant progress in engineering monitoring and geologic carbon storage.Building on this foundation,the paper analyzes the current focus of well logging technology research both domestically and internationally,and discusses trends in the development of well logging technologies in areas such as logging while drilling(LWD)deep detection and multidimensional data integration,artificial intelligence,rock physics and digital rock,multi-technology integration,and energy transition.Furthermore,the paper offers practical recommendations for the development of domestic LWD technologies,the integration of artificial intelligence with logging technology,digital rock,and logging technologies to address the energy transition.
