一种CO2压裂用远程控制高压卸荷系统及使用方法
摘要：
本发明属于油气田勘探开发技术领域，具体涉及一种CO2压裂用远程控制高压卸荷系统。它包括一单向阀,所述单向阀的出口连接一压裂主管线，入口连接与一旋塞阀；所述旋塞阀连通一T型直角三通的一个端口，所述T型直角三通的另外两个端口分别连接一远程控制高压卸荷旋塞阀和CO2压裂泵车；所述远程控制高压卸荷旋塞阀连接一通径放压堵头和一旋塞阀执行器，所述旋塞阀执行器通过两线缆分别连接压裂车电瓶和本地仪表控制箱。该系统可使地面管汇操作人员远离高压区，确保人员健康安全，同时大幅提高压裂准备循环冷泵效果。
摘要（英）：

The invention belongs to the technical field of oil and gas filed exploration and development and particularly relates to a remote control high-pressure unloading system for CO2 fracturing. The system comprises a one-way valve, an outlet of the one-way valve is connected with a fracturing main pipeline, and an inlet of the one-way valve is connected with a cock valve. The cock valve is communicated with one port of a T-type right-angle tee joint, and the other two ports of the T-type right-angle tee joint are connected with a remote control high-pressure unloading cock valve and a CO2 fracturing pump truck. The remote control high-pressure unloading cock valve is connected with a drift diameter pressure release plug and a cock valve executor, and the cock valve executor is connected with a fracturing vehicle storage battery and a local instrument control box through two cables respectively. By means of the system, ground manifold operators can be made far away from a high-pressure area, health and safety of people are guaranteed, and meanwhile the efficiency of a fracturing preparation circulating cold pump is greatly improved.
