【摘要】 九龙山构造是川西北地区的重点勘探构造。据地震剖面分析,解析了九龙山的构造几何学特征。研究表明,九龙山背斜受到米仓山构造和龙门山构造的双重影响,主要经历了三期次构造叠加,其叠加组合形成了现今九龙山的复杂构造。通过合理的构造建模,对九龙山构造运动过程、多期构造叠加及油气运移与分布规律等有了新的认识。更多还原

【Abstract】 The Jiulongshan structure is key one in northwest Sichuan.This paper deals with its structural geometry based on seismic data.The study indicates that the Jiulongshan anticline was affected by both the Micangshan structure and the Longmenshan structure and subjected to three tectonic superimpositions.Structural kinematics is modeled based on which an approach to the multiple structural superimposition,oil-gas migration and accumulation are made.更多还原
