摘要
水力扩张式封隔器具有悬挂式固定,液压坐封,液压解封特点,可以应用于油气水井分层、分段压裂改造。介绍了水力扩张式封隔器结构组成和基本原理,并在直井XC3-6中成功应用,取得较好压裂效果。
The hydraulic expansion packer has the characteristics of hanging type fixed, hydraulic sealing and hydraulicdecapsulation, which can be applied to oil and gas well stratification and fracturing.The structure and basic principle of the hydraulicexpansion packer are introduced and successfully applied in the straight well XC3-6 to obtain better fracturing effect.
