摘要： 立足“十三五”期间的研究成果，总结地质与物探相结合的方法，突出智能化技术应用，形成岩性地层区带评价、圈闭边界识别和有效性评价2项技术体系，①以断层/砂体输导体系定量评价、基于断层破坏程度细化分析的泥岩盖层有效性评价、地层不整合风化黏土层识别与封堵性定量评价为核心的源外岩性油气藏和地层油气藏区带评价技术体系；②形成以隐蔽层序界面识别与高频层序格架建立、基于多属性变时窗波形聚类为基础的沉积体宏观分布地震预测、基于稀疏理论地震反演和最小地震干涉分析的薄互储层预测等为核心的岩性地层圈闭边界识别与有效性评价技术。这些技术方法在推广应用后，为在相关盆地部署风险探井提供了有力的技术支撑。

Abstract: Based on the research results during the 13th Five-Year Plan period,two sets of technology system of play evaluation,trap boundary identification and effectiveness evaluation for lithostratigraphic reservoirs were summarized by combining geology with geophysical exploration and highlighting the application of intelligent technology.(1)The play evaluation technology system for lithostratigraphic reservoirs outside the source area is based on quantitative evaluation of fault/sand body migration system,effectiveness evaluation of fault-related mudstone seals,weathered-clay identification in unconformity belt and quantitative evaluation of sealing ability. (2)The trap boundary identification and effectiveness evaluation technology system for lithostratigraphic reservoirs is based on the recognition of subtle sequence boundary and the establishment of high-frequency sequence framework,seismic prediction of sedimentary system distribution based on multi-attribute clustering in laterally changing seismic window,and thin interbedded reservoir prediction based on sparse theoretical seismic inversion and stratal slicing using minimum seismic interference frequency data. After being popularized and applied, these technologies provide strong technological support for deploying risk exploration wells in related basins.

Key words: lithostratigraphic reservoirs, play evaluation technology, trap evaluation technology, migration system, sealing effectiveness, weathered-clay bed, unconformity structure
