摘要
利用地质及地震资料,运用Basin2软件对东营凹陷的油气运聚进行数值模拟。研究结果表明:①东营凹陷的生油区主要为利津洼陷和牛庄洼陷;②超压层位主要分布于沙河街组的沙三段下亚段、沙四段以及孔店组,油气的运移和凝聚主要发生在东营组和馆陶组至明化镇组沉积时期;③油气聚集带与超压的分布具有一定的耦合关系,超压体系的中弱带以及流体势低的地方为有利的成藏区,是今后勘探的重点区域。
Use of geological and seismic data, the hydrocarbon migration and accumulation are quantificational simulated by Basin2 in Dongying depression. The results as following：Lijin and Niuzhuang are sags of producing oil;The overpressure stratum of Dongying depression is mainly distributed in the stratum of lower of Shahejie FormationⅢ, Shahejie FormationⅣand Kongdian Formation, the migration and accumulation time of the hydrocarbon fluid is at the Dongying Formation, and the period of Guantao Formation to Minghuazheng Formation. Overpressure distribution and the distribution of hydrocarbon accumulation zone with a certain degree of coupling relations. The area, which has low fluid potential should be favorable for pool-forming, is very important for later exploration.
