通过岩心薄片鉴定、扫描电镜、压汞法、全岩X-衍射、分析化验等方法,结合阵列声波测井资料对何日斯太凹陷T2井区储层的岩性特征、分布特征、孔隙结构特征、裂缝特征、物性特征、粘土含量和粘土矿物组份、敏感性几个方面进行研究,研究表明该区域储层是低孔特低渗储层,属三类储层。 Through the methods of core slice identification, scanning electron microscopy, whole rock X-ray diffraction, analysis and testing, combined with array acoustic logging data, the lithology characteristics, distribution characteristics, pore structure of reservoirs in well T2 of Hedesitai depression The study shows that the reservoirs in this area are low porosity and low permeability reservoirs and belong to three types of reservoirs.
