摘要
针对常规悬挂器不能满足大斜度井及水平井尾管固井要求的问题，研制了特殊尾管悬挂装置。这种装置有４个规格，主要由尾管挂总成、送放工具、密封盒总成、送球器、锁紧座、大小胶塞、回接筒和回接插头组成，结构合理，操作简便，送球可靠，坐挂成功率高。大小胶塞设有锁紧机构，注完水泥后可防止回压，且附件具有良好的可钻性；密封心子能随送放工具提出井口；倒扣操作简便，找中和点方便。经南海、渤海和大港油田的使用证明，特殊尾管悬挂装置坐挂成功率高，能满足现场使用要求。
A special liner hanger for use in cementing of high deviated
holes and horizontal holes is developed. The hanger has four sizes, is comprised of liner
extension assembly, running and releasing tool, packing assembly, ball carrier, ball seat, big
and small rubber plugs, retrieving tools, and is characterized by rational structure, convenient
and reliable operation. The big and small rubber plugs has locking mechanism to prevent back
pressure and has good drillability. The sealing element can be pulled out with the running and
releasing tool. And it is easy to unscrew and to seek the central point. Field operation shows
that the special liner hanger can satisfy the operating requirements with high success rate of
setting.
