实施强化采液是特高含水期油田减缓产量递减,改善开发效果的有效途径.针对中国大多数砂岩油田采用多套井网开发的实际,建立的“两个界限、三重分级”单井最大提液潜力评价方法,量化了不同单井的技术经济界限,规范了操作流程.提出了以采液比例符合程度和储采比均衡系数为核心的确定产液规模的综合指标评价体系,该体系能够反映多层系开发油田的均衡开采特征,对不同类型、不同开发阶段油田的提液潜力评价具有较强的参考价值.实例应用证明,该提液潜力评价系统能够有效地评价油田的提液潜力.%The stimulatioon of liquid increase is an effective way to slow down the oil production decline and improve the development effects of the oilfields in the stage of super high water cut . For the reality of multiple sets of well patterns employed in most sandstone oilfields at home, the evaluating methods of maximal liquid increase for the individual well with "two limits and triple grades" are established, thus the technical and economic limits of the different single wells are quantified and moreover the operational flow sheet is specified. In addtion, taking the ac-cordent degree of the liquid produced proportion and the balance coefficient between the reserve-production ratio as the heart, the comprehensive index evaluating system for the determination of liquid producing size is presented. The system can reflect the balanced exploitation characteristics of multi -layered oilfields and moreover possess much stronger reference value to the potentials'evaluation of the oilfields with different types and stages of development. The application of the case history proves that the evaluating system of liquid increase potentials can effectively assess the potentials of the oilfield.
