摘　　要：基于低渗透储层评价和油藏开发经验,从低渗储层孔隙结构和渗流能力方面出发,引进主流喉道半径、可动流体百分数、启动压力梯度、黏土含量和原油黏度作为评价参数,建立了姬塬油田延长组长8段储层评价体系,采用模糊数学理论分析方法,对研究区储层进行综合分类评价,并研究了储层的平面分布特征。Based on the evaluation and development experience of low permeability reservoirs, builds up the evaluation system of low permeability reservoirs of the eighth member of the Yanchang formation in Jiyuan oilfield in terms of specific pore structure and permeability using main throat radius, movable fluid saturation, starting pressure gradient, the contents of clay and the viscosity of underground crude oil. Fuzzy mathematics and comprehensive evaluation method are used tentatively in quantitative reservoir classification and evaluation in the study area, and the planar distribution characteristics of reservoir are also studied.
