水井管柱发生高凝油卡钻,不仅增加了水井成本,而且施工占井时间长,影响了水井的注水量及油井的稳产。作业过程中通过多种方法手段判断水井管柱被卡的类型。确定注水管柱油卡后。针对不同井的情况,提出了烫洗环空法,管内热洗法,热洗套冲法等来解决注水管柱高凝油卡。生产实践证明烫洗环空法,管内热洗法,热洗套冲法能快速高效的解除注水管柱高凝油卡,避免了大修作业,提高了作业速度,节约了成本,为水井快速恢复注水提供了保障。
The occurrence of high condensate card stuck in the well pipe string not only increases the cost of the well, but also takes a long time to occupy the well, affecting the water injection volume of the well and the stable production of the well. During operation, the method of determining the type of well pipe string stuck is determined by a variety of methods. After determining the water column oil card. According to different wells, put forward the scouring ring air method, the tube heat washing method, hot wash sets Chong method to solve the high concentration of fuel injection pipe column card. The production practice has proved that hot air flushing method, heat washing method in the pipe and hot wash method can quickly and efficiently lift the high pour point oil card of the water injection column to avoid the overhaul operation, increase the operation speed, save the cost and quickly restore the well Water provides a guarantee.
