【摘要】 龙门山冲断带前缘地区发育大量油气田或含油气构造,主要分布在安县构造转换带和灌县构造转换带,通过野外地质调查和典型地震资料解析,结合沉积相分布特征,研究其构造带对油气成藏的控制作用。结果表明,安县构造转换带和灌县构造转换带具有较好的陆相碎屑岩储集层展布特征,并且具有较为有利的构造圈闭,即中浅部发育冲起构造型圈闭,深部发育与滑脱层相关的双重构造圈闭,因此安县构造转换带和灌县构造转换带具有较好的油气勘探前景。更多还原

【Abstract】 Many oil and gas fields or traps developed in the frontal area of Longmen Mountains thrust belt by hydrocarbon exploration,and they mainly locate in Anxian transfer zones and Guanxian transfer zones.By analyzing the sedimentary and tectonic characters of the transfer zones,the control effects of the transfer zones on hydrocarbon accumulation were studied.The results show that the two special areas have favorable terrestrial clastic reservoirs and some preferred structural traps,such as pop-up traps in shallow-middle depth and some duplex traps in deep.The transfer zones have profitable hydrocarbon exploration.更多还原
