摘要

摘要: 本文依据岩石薄片、铸体薄片、物性分析、压汞曲线等资料，对鄂尔多斯盆地什社地区延长组长3₁储层特征进行了深入的研究。研究分析认为：什社地区长3₁储层主要为长石岩屑砂岩和岩屑长石砂岩，属于低孔—特低孔、特低渗—超低渗储层，储集空间主要为粒间孔和长石溶孔。储层的分布主要受沉积相带的控制，后期成岩作用对储层的储集性能也有一定的改造。综合储层分类评价标准，将研究区储层分为3类，什社地区长3₁油层组以Ⅰ类、Ⅱ类储层为主。

Abstract: Based on the data of rock thin sections, casting thin sections, physical property analysis and intrusive mercury curves, the characteristics of Chang 3₁ reservoirs of Yanchang group in Shishe area of Ordos Basin were studied. The results show that the reservoirs of Chang 3₁ in Shishe area are mainly composed of feldspar lithic sandstone and lithic feldspar sandstone, belonging to low-ultra low porosity and low-ultra low permeability reservoir. The main pore types are intergranular pore and feldspar dissolved pore. The distribution of reservoirs is mainly controlled by sedimentary facies and the diagenesis afterwards also affects the reservoir properties. According to the evaluation criterion, the reservoirs of the study area can be divided into three types. Chang 3₁ reservoir group in Shishe area mainly are type Ⅰ reservoir and type Ⅱ reservoir.
