岩性油气藏是东营凹陷的重要勘探领域,按照油气来源划分为两种类型,自源型岩性油气藏和他源型岩性油气藏,两类岩性油气藏的运聚模式特点明显不同,自源型岩性油气藏成藏的运聚模式具有“近邻排放,自生自储”的特点,烃源岩包裹砂岩储集体,油气直接排注,在砂岩储集体中富集成藏;他源型岩性油气藏成藏的运聚模式具有“远程运移,异源成藏”的特点,下伏层系的油源,通过深切断层和隐蔽输导体系组成的复杂油气运移通道,进入砂岩储集体聚集成藏。
Lithologic reservoirs are important exploration areas in Dongying Sag. According to the sources of oil and gas, they are divided into two types, self-source lithology reservoirs and other source lithologic reservoirs. The characteristics of migration and aggregation modes of two types of lithologic reservoirs are obviously different , The self-sourced lithologic reservoirs have the characteristics of “near-neighbor emission and self-genesis and accumulation”. The source rocks enclose the sandstone reservoirs and the hydrocarbons are directly injected into the sandstone reservoirs for enrichment and accumulation. He The hydrocarbon accumulation and accumulation model of source lithologic reservoirs has the characteristics of “remote migration and heterogenous accumulation”, the source of oil in underlying layers, the complex hydrocarbon migration through deep fault and concealed transport system Channel, into the sandstone reservoir aggregation accumulation.
