摘　　要：对于油田生产状况的评价、规划是实现油田开发科学化和合理化的重要依据。选择井数、作业工作量、吨油成本、吨水成本、井次成本、产油量和措施增油量等构建了评价指标体系,与数据包络分析法相结合,分析、评价了油田生产状况。通过评价对象DEA是否有效判断生产投入与产出达到最佳,在DEA无效的情况下可定量给出需要改进的工作量。该方法不仅可以对不同油田之间的生产状况进行评价,也可以对同一油田按时间序列进行对比评价,并找出生产状况变化的原因,从而为决策者提供重要的管理决策信息。Many oilfields in China have entered high water-cut stage,it is difficult to maintain production and control water cut.Assessment of oil production situation and oilfield development planning is important to develop reservoir scientifically and reasonably.Evaluation index system is constructed using the number of wells,workover,cost of producing oil,cost of injection water,cost of wells,oil production,and incremental oil by stimulation.Combined with data envelopment analysis method,the oilfield production status was analyzed and evaluated.Evaluation of the effectiveness of DEA is used to determine whether the inputs and outputs achieve the best.If DEA is not valid,the amount of work needs to be improved can be provided quantitatively.This method can evaluate the oil production situations for different oilfields and compare chronologically in same oilfield.The reasons resulting in the change of oil production can be identified which can provide important management decision-making information for decision-makers.
