摘要
在高含水期碎屑岩储层剩余油形成条件、分布规律及控制因素分析的基础上,选取剩余油饱和度、储量丰度、砂体类型、砂体位置、所处位置、连通状况、微构造形态、注水距离、射开完善程度、注采完善程度、渗透率变异系数等11项静态和生产动态指标组成剩余油潜力评价因素集,并对各因素进行层次划分及权系数统计分析,采用多级模糊综合评判方法,以M油田为例对复杂非均质油藏剩余油潜力进行定量评价,将A、B主力层各井组划分为Ⅰ～Ⅲ类潜力区,从而建立剩余油潜力分析量化模型,实现剩余油定性分析结果的定量化描述。
The remaining oil potential in the complex heterogeneous reservoir of the Fanjiachuan oil field is quantitatively evaluated by applyting multilevel fuzzy judgement method,in the evaluation of remaining oil potential the remaining oil abundance,sand-body style,sand-body location and pace,connection status,microscopic construction configuration,producer-injector spacing,perforating completely penetrating degree, producer-injector perfect degree,permeability variation coefficient were selected as factor fors on the bases of analysis of formation condition,distribution and controlling factor of the remaining oil. Tthe hierarchical structure and power coefficient of all factors are statistically analyzed .The A,B major reservoir in is divided into Ⅰ,Ⅱand Ⅲ potential sections by which the quantitative model of the remaining oil potential evaluation is buit up and thus the qualitative description of qualitative analysis result of remaining oil could be realized.
