摘要
几十年来,中国油气勘探工作主要在陆相沉积中进行,其沉积模式和生储油岩的关系大体是,生油岩形成于深湖相、半深湖相和沼泽相,储油岩则在许多环境都能形成,在中国以三角洲相、冲积扇以及浅湖滩坝为主,而盆地基岩风化壳也有重要意义。在沉积过程中生油岩和储油岩常呈旋回出现,形成生储盖组合,可分为下生、上生、自生和侧生4种形式。
Abstract For scores of years, the petroleum exploration of China has been mainly targeted at non-marine sedimentary facies. However, the relations of sedimentary patterns with source and reservoir rocks are roughly as follows: source rocks occurred in deep lacustrine,hypabyssal lacustrine and paludal facies, while reservoir rocks could be developed in various environments, in China being predominated by deltaic facies, alluvial fan and shallow lake beach-bar, as well as the weathering crust of basinal basement rocks. During the process of sedimentation, the source and reservoir rocks generally occurred in cycles,which can be grouped into source-reservoir-cap assemblages distinguished as 4 types i. e.lower, upper, auto-land lateral geneses.
