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N_1-N_2~11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 analysis data of petrographic thin slices, cast thin slices, scanning electron microscopy, physical properties, capillary pressure curves and clay compositions of coring wells, combined with the interpretation of logging physical properties of reservoirs, the N_1-N_2 ~ 11 The reservoir reservoir is comprehensively evaluated from the aspects of rock characteristics, diagenesis, pore structure, physical property and heterogeneity. It is considered that the reservoir is a set of mesopore-medium permeability reservoirs whose physical properties are mainly affected by sedimentary facies and diagenesis Effect of the reservoir performance is medium, with strong intralayer and planar heterogeneity, inter-layer heterogeneity is weak, in the mining process to prevent edge water along the high permeability section to the rapid internal advance, affecting the mining Yield.
