摘　　要：油田开发效果评价贯穿油田开发的整个历程,是明确挖潜方向、确定调整措施的重要手段。针对目前油田开发评价指标多、工作量大、计算繁琐且评价周期长的问题,从状态对比法出发,通过构建“一主两辅”三图版,以理论曲线与实际生产曲线对比,以偏离平均水平为指导,明确开发区块开发效果的优劣,实现区块历史对标评价。为了使评价结果更客观全面,构建8项地质指标体系及7项开发效果综合性指标评价体系,实现开发现状定量评价。按照简单易行、操作性强、指标独立等原则,优选5项控制性开发指标,通过合理确定指标界限,明确区块差距及潜力方向;通过多指标综合分析,确定合理调整对策。研究成果简单实用,对类似区块的开发效果评价具有重要的推广价值。The evaluation of oilfield development effect is carried out throughout the process,which is an essential means to clarify the potential tapping direction and determine the adjustment measures.Aiming at the current problems of oilfield development evaluation indexes,heavy workload,cumbersome calculation,and long evaluation cycle,starting from the state comparison method,through the construction of“one main and two auxiliary”three charts,the advantages and disadvantages of the development effect of the development block are clarified by comparing the theoretical curve with the actual production curve and guiding the deviation from the average level,to realize the historical benchmarking evaluation of the block.In order to make the evaluation results more objective and comprehensive,eight geological index systems and seven comprehensive index evaluation systems for development effect are constructed to realize the quantitative evaluation of current development status.According to the principles of simplicity,practicability,and independence of indicators,five controlling development indicators are selected,the block gap and potential direction of the block are defined by reasonably determining the boundaries of the indexes,and the reasonable adjustment countermeasures are determined through comprehensive analysis of multiple indexes.The research results are simple and practical and have significant popularization value for the development effect evaluation of similar blocks.
