•Purpose目的: Pre-qualify SSSV’s to API 14A & Rogaland Test Requirements预先具备API14A和Rogaland 测试所需 标准 •Flow testing with clean water or sand slurry用清水或泥浆 做流压测试
•Test Long Assemblies, SSSV’s, and
Expandable
products测试较长总成,如井下安全阀和可膨胀设备
•Snubbing Jack – Tension/Compression抗拉,抗压测试装置

POW!
Subsurface Safety Valve
• A Subsurface Safety Valve is a device which automatically shuts in the well in case of a major malfunction of the surface equipment, preventing the uncontrolled flow of hydrocarbons to the surface.井下安全阀是一种在 井口出现重大故障时，自动关井的 装置。防止井喷。
To prevent environmental contamination due to uncontrolled hydrocarbon flow.保护环境，防止由于油气喷 出造成的污染。 Law requirements. Many countries’ laws require the installation of SSSV Offshore.法律要求。许多国家要求安 装井下安全阀，尤其海上完井。

Pressure
Subsurface Safety Valve OPEN CLOSED
• Apply Hydraulic Pressure to the Control Line 液压控 制管线 Acts on the piston作用在活塞 Moves the SSSV towards the open position.开启 安全阀 Hyd. Press. ≥ Form. Press. + Op. Press. 液压≥地层压力+开启压力
•Test pressures to 15,000 psi测试压力达到15000psi
•Capable of flow testing with water at temperatures from ambient to 195°F压力测试时温度从环境温度到华氏 195°可调 •Up to 30,000 psi below grade gas test cell高达30， 000psi的气体测试装置 •Remotely actuated pneumatic controls远程气压控制
Reliability – Design 可靠性-设计 • Unique Features特点： Only Offered by Halliburton In All of It’s TRSV’s只有哈里伯顿油管可回收安全阀才能全部
