为了提高油田的最终采收率和经济效益 ,在油田开发后期 ,对各种采油工艺措施的合理配置进行了系统研究。首先对油田开发效果进行评价 ,明确油田剩余潜力并指明措施方向 ,然后建立措施配置目标、规划数学模型、求得年度措施工作量 ,最后考虑油田每口单井的具体地质状况和生产状况 ,将各措施工作量落实到单井 ,并对措施整体实施效果做出预测和评价。本方法已在大港油田官 10 4断块成功应用。
In order to improve the final recovery rate and economic benefits of the oilfield, a systematic study on the rational allocation of various oil recovery process measures has been conducted in the late stage of oilfield development. First of all, evaluate the effect of oilfield development, identify the residual potential of oilfields and specify the direction of the measures, then set up measures to allocate targets, plan mathematical models and calculate annual measures. Finally, consider the specific geological conditions and production conditions of each single well in the oilfield. The workload of each measure is implemented into a single well and the forecast and evaluation of the overall implementation effect of the measure are made. The method has been successfully applied in the block 104 of Dagang Oilfield.
