摘要
以取心井的岩石薄片、铸体薄片、扫描电镜、物性、毛管压力曲线、粘土成分等分析资料为基础，结合储层的测井物性解释结果，对尕斯库勒油田N1-N^12心油藏储层从岩石特征、成岩作用、孔隙结构、物性特征、非均质性等方面进行综合评价，认为该储层为一套中孔-中渗储层，其物性主要受沉积相和成岩作用的影响，储集性能中等，具较强的层内和平面非均质性，层间非均质性较弱，在开采过程中要防止边水沿高渗透段向内部快速突进，影响采收率。
Based on the analytical data of cored wells, such aspetrographic thin section, cast thin section, scanning electron microscope, poroperm characteristics, capillary pressure curves and clay components, and in combination with logging interpretations of reservoir poroperm characteristics, the H1 - N21 reservoirs in Gaskuier oilfield are comprehensively studied in respects of rock characteristics, diagenesis, pore structure, poroperm characteristics and heterogeneities. It is believed that the reservoirs have medium porosity and medium permeability, which are mainly influenced by sedimentary facies and diagenesis, strong intraformational and areal heterogeneity, and weak inter-formational heterogeneity. Measures should be taken to prevent rapid fingering of edge water through highly permeable zones during production, which might influence recovery factor of oil.
