摘要
针对环空压裂时油管经常被严重损坏,甚至被割断落井问题,研制了环空压裂专用悬挂器。该悬挂器具有结构简单、耐冲击、耐磨削等特点。介绍了悬挂器的设计思路及组成。现场应用7口井,施工成功率100%,满足了施工要求,具有良好的推广应用情景。
Aiming to solve the problem of the tubing seriously damaged, even cut by high rate sand and fell into bottom hole during annulus fracturing treatment, a special hanger was designed. It has the characteristics of simple structure, shock resistance and polish durability. The design thinking and compose of the hanger were introduced. The practical use, in 7 wells with success ratio up to 100%, satisfied the requirements of treatment and has a good future.
