摘要
应用单井及二维盆地模拟、油源对比、流体包裹体定年等方法和技术,对黄河口凹陷烃源岩生烃演化史、BZ34断裂带油气运移通道、油气来源和充注历史的研究结果表明:在新构造运动活动地质背景下,油气成藏可以在数百万年内快速完成。在新构造运动活动带,活跃烃源岩及其持续快速、充足的供烃能力、断裂贯通型输导格架高效的油气汇聚效应与快速穿层运移是油气晚期多层系快速成藏的主控因素。
An integrated study on petroleum accumulation of BZ34 fault zone in Huanghekou Sag was carried out, including the hydrocarbon generation history,conduit system, petroleum sources and petroleum charging processes by means of single well,2-D basin modeling,oil-source correlation and data of fluid inclusion. It is concluded that petroleum migration and accumulation could be completed only in several million years during neotectonic stage. The main controlling factors for the late-stage rapid petroleum charging in neotectonic active zone include active source rock, fast hydrocarbon generation,pass-through conduit system,and high efficiency for hydrocarbon convergence and cross-layer migration.
