摘　　要：针对大斜度井注水工艺技术在应用中封隔器的解封难度,将同心分层注水技术应用在井斜角30°~50°的大斜度井上,研制了大斜度井注水封隔器、桥式同心配水器与配套工具,为辽河油田油田水驱开发的规模实施提供了技术支持和保障。Water injection packer,concentric bridge water regulator and supporting tools were developed to solve thedifficulties of packer releasing in water injection for high angle wells in which concentric layered water flooding is applied in well highangle wells ranging from30°to50°,which provide technical support and guarantee for the implementation of water floodingdevelopment in Liaohe Oilfield.
