| 摘 要： | 储集层岩石的孔隙结构不仅对油气储量,而且对油气井产能和最终采收率都有影响,在研究中根据实验得出的孔隙结构参数用来表征孔隙结构的优劣程度,便于在油气勘探与开发中应用1]。通过对合水地区长8储层的研究认为,长8储层砂岩类型以长石砂岩、岩屑长石砂岩为主,为近源沉积体系,是典型的低孔低渗储集岩。油组内不同小层的物性存在着差异,相比之下,长81小层储层物性最好,含油面积较大,长82小层储层物性较差,局部发育含油富集区。

| Abstract: | The interstice texture of Reservoir has an influences not only on oil and gas reserves,but also on productivity of oil and gas well and the ultimate recovery.The study indicates that sandstone from the Chang 8 consists mainly of arkose and lithic arkose of proximal facies and belongs to low porosity and low permeability reservoir rocks and the Chang 81 has better property. |
