本文利用储层地质学理论,结合岩心、铸体薄片以及分析测试资料,对哈拉哈塘地区晚泥盆世东河砂岩储层特征进行研究。研究认为东河砂岩以岩屑石英砂岩和岩屑砂岩为主,发育残余原生粒间孔—粒间溶孔组合为主的孔隙结构特点。并对东河砂岩段的物性特征进行分析,孔隙度与渗透率具有很好的相关性。通过统一储层评价标准,对研究区进行储层的综合评价。
In this paper, the characteristics of the Donghe sandstones of the Late Devonian in the Halahatang area are studied based on the theory of reservoir geology, core and thin castings, and analytical test data. The study shows that the Donghe sandstone is mainly composed of lithic quartz sandstone and lithic sandstone, and is characterized by the pore structure characterized mainly by the combination of residual primary intergranular pores and intergranular dissolution pores. And physical characteristics of Donghe sandstone are analyzed. Porosity and permeability have a good correlation. Through the unified reservoir evaluation criteria, the reservoir area comprehensive evaluation.
