摘要
本文应用灰色系统理论中关联度分析方法,以川东地区卧龙河、张家场、福成寨、沙罐坪等石炭系气藏24口井292块岩样压汞试验毛细管压力资料为基础,分析了该地区石炭系碳酸盐岩储层孔隙度与孔隙结构参数和渗透率之间的关系,进而分析了孔隙结构对岩样非润湿相采收率的影响。
Using the relation grade analysis method of grey system theory and based on the capillary pressure data by mercury injection for 292 rock samples from 24 wells drilled in the Carboniferous gas reser- voirs of Wolonghe, Zhangjiachang, Fuchengzhai and Shaguanping, etc., in eastern region of Sichuan, this paper analyzes the relation between the porosity and pore structure parameters and permeability, then the effect of pore structure on the recovery of non-wetting phase to the rock.
