杏6-7区整体调剖优化决策技术

Research and application of optimized decision technique for the whole profile control in Xing 6-7 area.

针对杏北油田含水上升过快 ,产量递减异常的问题 ,分析了区块整体调剖优化决策的理论基础 ;结合杏北油田油藏特点和井网结构 ,从选井、选层、选剂和效果预测几个方面对杏 6 - 7区西块试验区进行了区块整体调剖方案优化。根据优化结果开展了现场试验 ,预测结果与现场实际吻合较好 。

The research of whole profile control technique of the block is developed for the problems of too rapid rise of water cut and abnormal production decline. The theoretical basis on optimized decision for the whole profile control of the blocks is analyzed in this paper. And the project optimization of the blocks is implemented in test site of west block in Xing 6?7 area from several aspects of well, layer, agent selection and result forecasting combined with the reservoir characteristics and pattern configuration of Xingbei oilfield. Field experiments are carried out based on the optimization results. It shows that the predicted results tally with the field fact. It has a certain directive significance on working out comprehensive management project of the blocks.
