摘要
本文针对碎屑岩储层,应用毛管压力曲线资料,通过孔隙结构概率图和孔隙结构三大类参数——孔喉大小、分选性、连通性研究及模糊聚类分析等方法,确立了低渗透油层物性下限,并与国内外低渗透油层参数下限作了类比,经试油及储量复算证实效果是好的,可作为新、老油田确定储油层有效厚度的借鉴。
In this paper, the cutoff properties for low permeable clastic reservoirs are estimated by means of fuzzy cluster analysis of three porestructureparameters, i. e. throatsize, sorting and continuity, combined with porestructureproba—bility map. The reestimation result of OIP is correct when checked with production test data and compared with other cutoff values. The technique can be used as a guideline for determing net pay of reservoirs in both new and old oil—fields.
