油管携带可回收式井下安全阀是完井生产管柱的重要组成部分，可以实现井中流体的流动控制，要求高性能和高可靠性。安全阀稳定的液压驱动装置增强了工具的耐用性，其独特的结构有效的隔离了流体进入内部管柱。安全阀在主体连接和关闭装置 处采用了整体金属对金属密封，即节约了成本又实现了优质密封。简单、紧凑的设计 提高了安全阀的整体可靠性，可有效减少作业故障。

主要特性

◎ 采用金属对金属密封实现封井；

◎ 独特的液压执行元件(单片活塞/流动管)；

◎ 液压室结构实现了安全阀内部大多数结构与外部流体的有效隔离；

◎ 蕞大的活塞面积和弹簧力。

主要优点

◎ 金属对金属瓣阀密封已经证实可以用于防砂服务；

◎ 阀的寿命长；

◎ 阀开关力的蕞大化；

◎ 流动管结构可以有效防止井内碎屑等固体物质积淀于活塞上部；

◎ 实现了关键部件与井下环境的隔离。

TUBING RETRIEVABLE SUBSURFACE SAFETY VALVE

INTRODUCTION

Tubing retrievable subsurface safety valve is the important tool componentof completion production string. It can control flow of wellbore fluid. It requires high quality and high reliability. Hydraulic driving equipment of Safety valve enhance the reliability of tools. Its special configuration effectively isolates fluid into inner string. The main connection and key equipment use integrity metal to metal seal. It not only saves cost but also achieve high quality seal. Simple and compact design of safety valve enhances integrity reliability. It can effectively reduce operation failure.

FEATURES

◎ Isolate well by metal to metal seal;

◎ Special actuated elements (single piston, flow pipe);

◎ Hydraulic chamber configuration achieves effective isolation between the inner parts of SSSV and outer fluid;

◎ Biggest piston area and spring force.
