摘　　要：针对文卫濮结合部沙二下亚段潜在油气资源量大,而探明程度相对较低的地质特点,对目标区进行了整体构造格局、局部构造特征、砂体和储层物性展布状况,以及油气聚集成藏条件的研究。认为研究区为反向屋脊式半背斜断块圈闭,是非常有利的油气成藏单元;沙二下亚段储层在构造高部位十分发育且物性较好;柳屯凹陷和马寨次洼沙三、沙四段生成的油气沿文西断层向上运移到沙二下亚段储集层,沙一段及沙二上亚段稳定发育的大套泥岩是封盖能力很强的盖层,从而形成了下生、中储、上盖的成藏组合。根据研究成果指出了多个有利勘探目标,为下一步沙二下亚段滚动勘探提供了建议。For the geological feature of the second sand formation down huge potential oil＆gas reserves, low proven reserves proportion in Wen, Wei, Pu structure combination area, perform studies about whole structure framework, local structure character, sand body and reservoir bed physical property distribution status, oil ＆ gas accumulative and reservoir formation condition. Target area is semi-anticline block trap which is opposite direction ridge, and it is a favorable oil＆gas reservoir; Located in structural high place, the reservoir＇s sand body is very growing and good physical property;Oil＆ gas generates from the third, fourth sand formation in Liu-Tun concave and Ma-Zhai low-lying moves up along Wen-Xi fault to the second sand formation down reservoir, stable heavy-bedded mudstone grown in the first and second sand formation up reservoir is very good capping formation which can well seal oil＆ gas, thus these form the play： oil-forming in underside,oil reservoir in middle part and capping formation in upside. According to the study, several favorable exploratory target block is proposed, and the article gives the advice for further rolling prospecting in the second formation down reservoir.
