摘要
针对常规尾管固井重叠段固井质量差的问题,研制了新型封隔式尾管悬挂器。该悬挂器具有悬挂、封隔两种功能,能够有效地密封重叠段,防止油、气、水窜的发生。地面试验和现场应用表明,封隔式尾管悬挂器结构合理,密封可靠,操作简便,有效地解决了尾管固井过程中重叠段固井质量差的难题,具有极大的推广应用价值。
A new packer liner hanger has been developed to solve poor cementing problem often occurred in the overlaying interval in conventional liner cementing operation. The liner hanger with a packer performs functions of hanging and sealing, and can effectively seal overlaying casing interval so as to stop fluids from channe ling. Surface tests and field applications have showed its rational structure, liable sealing, and easy operating way. This tool has effectively solved foregoing problems and is great worthwhile being applied more widely.
