聚合物驱油现场试验的跟踪调整主要是对生产动态分析,注入井和采出井生产参数的调整,及时改变各井间的注采平衡关系,调整好层间和平面矛盾,扩大波及体积,提高聚驱效率。分析了某聚合物驱油试验区内井组间存在的平面干扰现象。由于试验区内注入采出井生产参数的不合理,影响了井组间聚合物溶液的平面波及体积,降低了井组间的聚驱效率。通过对注入采出井合理的生产参数的调整,可以有效的扩大平面波及体积,提高聚合物驱油效率。
The follow-up adjustments of polymer flooding pilot are mainly including production dynamic analysis,production parameters adjustment of injectors and producers,changing the injection/production balance between wells in time,adjusting in-layer and plane interference,expanding swept volume,increasing polymer displacement efficiency.The plane interference phenomenon between well groups of one polymer flooding pilot is analysed.Because the injector and producer production parameters were unreasonable in the pilot,polymer solution lateral swept volume of well groups was affected and the polymer displacement efficiency of well groups was reduced.By adjusting the production parameters of injector and producer reasonably,the swept volume could be expanded efficiently and the polymer displacement efficiency could be increased.
