【摘要】：针对海洋压裂作业船超高压快速脱离装置技术被国外垄断的现状,设计了一套压裂作业船超高压快速脱离装置。阐述了快速接头的结构及工作原理,并制定了装置整体作业方案。对该装置的主要部件(接头和液压执行结构)进行了设计。对快速接头的主要受力部件(限位块、插头体和阀芯)进行了有限元分析。分析结果表明:限位块、插头体和阀芯所受应力均小于各自许用应力,因此这3个主要部件在挤压状态下安全;该装置在超高压下可实现管路的自动快速脱离,并封闭管路;当遇到紧急情况时,超高压快速脱离装置可通过网络控制系统使压裂作业管汇连接断开,并保证无高压液体溢出,使得压裂船能够快速撤离。研究方法可为其他类似装置的结构设计提供参考。
[Abstract]:In view of the fact that the technology of ultra high pressure rapid detaching device for offshore fracturing operation ship is monopolized by foreign countries, a set of super high pressure rapid escape device for offshore fracturing ship is designed. The structure and working principle of fast joint are expounded. The main components (joint and hydraulic execution structure) of the device are designed. The main force components of the fast joint (limit block) are designed. The finite element analysis of the plug body and the valve core shows that the stress of the limit block, the plug body and the valve core is less than that of the respective allowable stress, so the three main components are safe under extrusion. The device can realize the automatic and quick breakaway of the pipeline and close the pipeline under the ultra-high pressure. When the emergency occurs, the ultra-high pressure quick detaching device can break the connection of the fracturing operation pipe through the network control system, and ensure that there is no high pressure liquid overflow. The research method can provide reference for the structural design of other similar devices.
