Abstract:
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 intoⅠ ,Ⅱ andⅢ 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.
