国外深井尾管悬挂器技术研究新进展

Advances in Liner Hanger Techniques in Deep Wells Outside China

跟踪调研了国外深井和复杂井尾管悬挂器技术研究进展情况,对国外7种新型尾管悬挂嚣,包括flex- lock尾管悬挂器、液压丢手式尾管悬挂器、封隔式尾管悬挂器、旋转式尾管悬挂器、内藏卡瓦式尾管悬挂器、多功能尾管悬挂器系统、尾管多胶塞系统进行了介绍和分析,使我们对国外尾管悬挂器的结构、性能特点及优缺点有一个系统的认识,为我国今后尾管悬挂器的研制、改进和创新提供了参考。

This paper traces the advances in liner hanger techniques employed in deep wells and complex wells outside China, and focuses on seven kinds of novel liner hangers including types of flex-lock, hydraulic dropping, packing, rotary, inner-hidden slip, multi purposes and multi plug system. Introductions and analyses of these liner hangers gives us a systematic understanding of their design, properties, advantages and disadvantages, which is sure to work as references to push forward liner hangers＇ innovation in China.
