朝阳沟油田属低渗透油田 ,地质条件极其复杂 ,研究表明本研究区块属中孔低渗储层 ,并按孔隙度、渗透率、孔隙结构特征及砂岩粒度、泥质含量将其分为四类储层。并根据大量的样品分析数据探讨了储层特征对含油性的影响 Chaoyanggou oilfield is a low permeability oilfield with extremely complicated geological conditions. The study shows that the study area is a medium-porosity and low-permeability reservoir, and is divided into four reservoirs according to porosity, permeability, pore structure characteristics, sandstone granularity and shale content Class reservoir. Based on a large number of sample analysis data, the effect of reservoir characteristics on oiliness was discussed
