射孔快速连接井口装置技术现状及分析

Technical Status and Analysis of Perforating Quick Latch

射孔快速连接井口装置是一种高度集成的机电液一体化装置,施工人员在远离井口的控制柜前,通过操作控制面板来实现防喷管和井口装置远程自动对接和自动释放,并能快速试压和自动投球,替代了传统的人工连接。介绍了国外射孔快速连接井口装置的结构及功能,分析了射孔快速连接井口装置的关键技术,主要包括工作原理,锁紧装置,高压密封、高压防硫材料,安全装置和控制系统。指出我国应尽快发展射孔快速连接井口装置。

Perforating quick latch is a highly integrated electromechanical hydraulic device,the operator can realize remote automatic wellhead latch,quick test and automatic ball injecting by operating the control panel far away from the wellhead control cabinet,instead of the traditional manual latch connection.The structure and function of foreign perforation quick latch wellhead devices were introduced,and the key technologies of perforation quick latch devices were analyzed,including working principle,locking device,high pressure sealing,high pressure anti-sulfur material,safety device and control system.It is recommend developing the domestic perforation and quick latch wellhead devices as soon as possible.
