摘　　要：川东北元坝地区陆相层序展现了良好的勘探潜力,成为油气增储上产的重要接替阵地之一。根据研究区三维地震解释资料,结合构造演化史、区域应力挤压对构造断层形成的作用分析,通过多套陆相典型层位与断层展布和交切关系的研究,总结了断层分布特征、断层发育期次与成因以及断层与油气成藏的关系。认为构造断层与其伴生裂缝的展布和发育特征是研究区陆相天然气聚集成藏的主控因素之一。In Yuanba area of northeastern Sichuan Basin, continental sequences not only appear a better exploration prospect but also become one of the most important substitutes for increasing both reserves and production. In this study, combining with 3D seismic interpretation, the effects of tectonic evolution history and regional stress compaction on forming faults are analyzed; moreover, the relationship between some typical continental sequences and fault distribution along with its intersection is explored; the distribution characteristics, development stages and origin of the faults, and the relationship between faults and forming reservoir are summed up. It is deemed that the main factors to form reservoir in this study area include fault, and its associated fracture's distribution and development features.
