经对孤东油田七区西Ng52 +3层聚合物驱工业性矿场试验过程中油水井间大孔道窜流的实际情况进行分析 ,探讨了化学示踪剂井间监测的机理 ;根据监测结果 ,讨论了油水井间的连通状况 ,实施了堵水调剖油藏调整。这项研究对于注聚区整体堵水调剖 ,扼制聚合物溶液窜流 ,扩大波及体积发挥了重大作用。
The actual situation of large channel cross-flow between oil and water wells during the test of Ng52 +3 polymer flooding in the west of Block 7 of Gudong Oilfield was analyzed, and the mechanism of cross tracer monitoring of chemical tracer was discussed. According to the monitoring results, Discussed the connectivity between oil and water wells, implemented a plugging water profile adjustment. This study has played a significant role in the overall water plugging and profile control, the strangling of the polymer solution and the expansion of the spreaded volume.
