多层合采油水井补层后,对新补层进行酸化、压裂等作业施工过程中,一般需将其余非新射孔层位封住,再对新射孔层进行措施处理,常用的暂堵方式有填砂和下封隔器两种。填砂施工简单便捷,但对井口袋大小、层间距离等有一定要求,且施工完成后需进行冲砂返排;下封隔器施工略复杂,下封后一般还需进行打压验封,对封隔器质量要求较高,同样施工完成后需要将封隔器提出。两种方法各有优缺,实际施工过程中应根据所施工井具体井况具体分析选用。 Multi-layered oil well after the pay, the new layer of acidification, fracturing and other operations in the construction process, the general need to seal the rest of the non-new perforated layer, and then the new perforated layer of measures to deal with the temporary There are two ways to block the way to fill sand and pack packers. Sand filling construction is simple and convenient, but there are certain requirements for the size of well head and the distance between layers. After the construction is completed, sand blasting is required. The construction of the lower packer is slightly complicated, Packer quality requirements are higher, the same construction needs to packer. The two methods have their own advantages and disadvantages, the actual construction process should be based on the specific wells well construction analysis and selection.
