| 摘 要： | 靖边气田盒8段砂岩地层成藏条件优越,是重要的产能接替层位。但该套砂岩致密,物性较差。通过岩石学、沉积相、成岩作用等方面研究,分析了盒8段砂岩岩性特征、物性特征,表明盒8段砂岩整体上为低孔、特低渗致密储层,储集空间以次生孔隙为主,孔隙结构较差;认为沉积作用控制了储层分布,但不同沉积微相沉积砂体物性总体差别不大,机械压实作用是造成盒8段砂岩孔隙度下降的主要因素,高岭石与绿泥石的胶结作用对砂岩孔隙的贡献存在两面性,而铝硅酸盐矿物和碳酸盐矿物溶解作用是研究区优质储层发育的控制因素。

| Abstract: | The He8 Formation develops a set of excellent accumulation conditions,and is an important succeeding layer in the Jingbian gas pools.But the sandstone is tight,and its physical properties are not good.According to study on the characteristics of petrology,sedimentary microfacies and diagenesis,and so on,the following under-standings were obtained.The He8 Formation is low porosity and ultra-low permeability reservoir.The secondary intergranular pores are the main pore space.And the pore texture is not prefer... |
