| 摘 要： | 根据大量岩石薄片和铸体薄片分析,对鄂尔多斯盆地长武地区三叠系延长组碎屑岩的沉积特征、储层孔隙结构及岩石物理性质进行了研究,认为延长组砂岩体有利相带为三角洲前缘水下分流河道微相和河口砂坝沉积微相,属于低孔隙度、特低渗透率砂岩储层。研究表明,该地区中北部是有利的油气勘探区带,经过钻探和在W10井试油,已获得工业性油流。

| Abstract: | According to the analysis of a large number of rock thin-sections and cast thin-sections, the depositional features, pore structure and rockphysical properties of clastic rocks in Yanchang Formation , Triassic system, Changwu Region, Erdos Basin has been researched. The beneficial phase belt of sandstone body in Yanchang Formation is considered as the delta-front underwater diffluence channel and sandbar micro-phase which is a low porosity and supper-low permeability reservoir. Those researches showed that the northern central part of this region would be benefit zones for oil and gas exploration . Through exploration drilling and production test of W10 well, we had gained commercial oil stream. |
