摘　　要：在油田开发降本增效的大趋势下,对注入剖面的监测比例、井点、频次进行量化和优化,使注入剖面监测既满足油层动用状况评价需求,又满足开发调整和措施评价需求,是油田开发特高含水后期注入剖面监测方案设计的重要课题。利用克里金插值误差的方差与监测井的个数和位置、空间相关结构有关的特点,确定最优监测井点质量评价方法,结合因子分析、聚类分析等大数据挖掘技术分析注水井属性特征,确定注入剖面监测比例,给出反映动用状况的最优监测井点,进一步根据油田开发实际需求,提出建立三级监测井点实施监测的优化方案。优化设计的部署方案在A开发单元应用,开发单元整体的年监测比例低于计划8%,调整和措施取得较好效果。Under the big trend of reducing the cost and increasing the efficiency of oilfield development,the monitored ratio,well point and frequency-time of the injected profile are quantified and optimized so that the profile monitoring can not only meet the requirements of the evaluation of the oil reservoir development conditions,but also meet the needs of the development adjustment and stimulation evaluation,so the quantification and optimization have been the important theme of the design of the injected profile monitoring of the oilfield development at the extra high watercut stage. Using the relationships between Kriging interpolation error variance and the number and position of the monitored wells and the related spatial structures,the evaluating method of the optimal monitored wellpoint quality was determined. And moreover integrating with the large-data digging technologies such as factor analysis,cluster analysis etc.,the attribute characteristics of the injection well were analyzed,properties and the monitored proportion of the injected profile was determined,the optimum monitored well-point reflecting the developedconditions was provided. And furthermore according to the actual demand of the oilfield development,the optimized monitoring plans of three-level well point were presented. The application of the optimized-design deployment plan in Developing Unit A shows that the overall annual monitored ratio was lower by 8% than that of the plan,and moreover the much better effects were achieved for the adjustments and the stimulations.
