Optimax? Series Tubing Retrievable Surface Controlled
Subsurface Safety Valve
——Model W(E)-5
The Optimax? Series Tubing Retrievable Surface Controlled Subsurface Safety Valve (TRSCSSV) is Weatherford’s entry into the Safety Valve market. Utilising the latest technology and design philosophy, this product is designed to maximise simplicity and reliability of operation. The Optimax? Series Model W(E)-5 Tubing Retrievable Safety Valve is a Rod Piston, Flapper Type Safety Valve, with a 5,000 psi Working Pressure rating, 1,000ft and 2,000 ft Setting Depth configurations and is available with an optional Self Equalising Flapper mechanism. Features: ? API Q1 and API 14A Quality programmes ensure design and manufacturing integrity ? Number of Pressure Seals / potential leak paths minimized ? No Complexity added to the Safety Valve to facilitate Lockout or Control Line
Communication ? Metal to metal Premium Thread Housing Connections as a standard feature ? Non-elastomeric Dynamic Seal System
? Non-elastomeric flapper soft seat to back up metal to metal primary seat ? Field-proven ‘Through the Flapper’ self-equalizing mechanism
?
The Control Line Communication and Lockout Tools are designed to be Slickline deployed,actuated and retrieved Benefits
? Design, material, manufacturing, assembly and test documentation retention ensures
conformance to industry standards ?
Optimised design for maximised reliability, potential leak paths minimised. Our Hydraulic
Control System has only 2 potential leak paths – the industry minimum
?
There are no sleeves, plugs or any other mechanisms which can be inadvertently actuated,
resulting in premature control line communication
? Premium housing connections as a standard feature optimises reliability ? No elastomeric seals are used, avoiding fluid compatibility and explosive decompression problems
? Robust, field proven Self-Equalising option provides for simple operation
?
Accessory Tools have been designed to utilise Slickline deployment, avoiding complex operational requirements Applications
The Optimax? Series Safety Valve is designed to operate in fluid and gas environments in both production or injection applications. An integral part of the completion string, it is controlled via a hydraulic control line. Application of control line pressure maintains the Safety Valve in the open position, but when pressure is bled off the safety valve closes. In the event of uncontrolled flow, this ‘failsafe’ closure on command protects property, personnel & the environment. In the event of malfunction, deployment of Lockout and Control Line Communication Tools adapt the valve to accept a Wireline

Control Line Communication Tool Wireline Insert Safety Valve As Requested API Q1 & API 14A 3S2 Optimax系列油管可回收式地面控制井下安全阀
——WP(E)-5, WP(E)-10型
Optimax系列油管可回收式地面控制井下安全阀（TRSCSSV）是威德福进入安全阀市场的入门产品。应用最新的技术和设计理念使这一产品结构最简单，操作达到最大的可靠性。Optimax系列WP(E)-5和WP(E)-10型油管可回收式安全阀是一种杆式活塞、活瓣型安全阀，额定工作压力为5,000psi或10,000psi，下入深度有1,000英尺和2,000英尺两种，有自平衡式活瓣机构供选择。这种型号的安全阀有一个高级活塞机构，活塞机构内装有全开和全关活塞止动密封。
特点：
? API Q1和API 14A质量程序确保设计和制造的完善性
? 压力密封和可能的漏失点的数量达到最少，工具的液压控制系统只有两个可能的漏失点——在行业中是最少的。
? 保持安全阀的简单结构，便于锁定打开或控制管线的连通 ? 外筒连接采用金属与金属之间的高级扣型是工具的一个标准特点 ? 非弹性动密封系统再配金属和塑料杆式活塞止动密封。 ? 非弹性活瓣软座作为金属与金属一级阀座的一种支撑 ? 经过现场检验的活瓣上下自平衡机构
? 控制管线连通工具和锁定打开工具用钢丝下入、操作和回收 优点：
? 设计、材料、制造、组装和试验记录的保存保证与工业标准相一致 ? 优化设计使可靠性最大，潜在的漏失点最少。
? 没有套筒、堵塞器或任何其它机构会意外动作并导致控制管线提前连通。 ? 外筒采用高级扣型是工具的标准特点，使工具达到最大的可靠性。 ? 工具不使用弹性密封，避免了流体相容和爆炸泄压问题的发生。 ? 坚固的、经过现场检验的自平衡机构使操作非常简便。 ? 设计的附属工具采用钢丝进行操作，避免复杂的作业需求。 应用范围：
Optimax系列安全阀设计用于生产井或注入井中的液体或气体环境，WP(E)-5和WP(E)-10型安全阀有一个高级活塞机构，可用于需求量较大的天然气或高压作业。安全阀是完井管柱的一个组成部分，通过液压控制管线进行控制，控制管线加压使安全阀保持在打开状态，压力释放后安全阀关闭。如果发生井喷，这种工具在人为控制下能可靠关闭，可有效地保护人员、财产和环境的安全。万一安全阀发生故障，可以用锁定打开工具和控制管线连通工具将安全阀改装成可下入一个插入式钢丝安全阀，减少生产的停顿。
