中原油田采油六厂开发区块因油层非均质性较为严重，渗流能力较差，采用ZY-Y341-114（原753－3）封隔器进行注水已无法满足分注的要求。而SL－Y341-115高压封隔器井下工作压差达到25MPa，比原来的ZY－Y341－114封隔原高5MPa。在结构设计上采用了悬挂锚定结构和液压应封方式，各
Because of the serious heterogeneity of oil layers and poor seepage ability in the development block of No.6 Production Plant of Zhongyuan Oilfield, the injection of ZY-Y341-114 (formerly 753-3) packer has been unable to meet the requirements of sub-injection. The SL-Y341-115 high-pressure packer downhole pressure to 25MPa, than the original ZY-Y341-114 packer original high 5MPa. In the structural design using the suspension anchoring structure and hydraulic sealing method, each
