石油和天然气作业中的超压事件可能引发多种严重后果，包括：

• 安全隐患：过高的压力可能导致设备破裂，进而引发火灾、爆炸或有害气体泄漏，使作业人员面临严重受伤甚至死亡的风险。

• 设备损坏：超压产生的压力可能导致昂贵的设备发生变形、破损或损毁，从而带来高昂的维修成本、停工损失以及生产力下降。

• 环境风险：石油、天然气或化学品的失控泄漏可能造成严重的环境破坏，包括发生溢漏以及向空气和水中排放有害物质。

Overpressure events in oil and gas operations can cause a variety of severe consequences, including:

• Safety Hazards: Excessive pressure can cause equipment to rupture, leading to fires, explosions, or the release of hazardous gases. This puts workers at significant risk of injury or even fatalities.

• Equipment Damage: The force exerted by overpressure can deform, break, or destroy costly equipment, leading to expensive repairs, downtime, and productivity loss.

• Environmental Risks: Uncontrolled releases of oil, gas, or chemicals can cause serious environmental damage, from spills to releasing harmful substances into the air and water.

超压可能由多种作业因素和外部因素引起。了解这些成因对于实施恰当的保护措施至关重要。

操作和流程原因

• 管道堵塞或阻塞：杂物、蜡质积聚或水合物形成可能阻碍流体流动，导致压力升高。

• 阀门故障或设备故障：压力控制阀无法正常开启或关闭，可能导致压力失控升高。

• 化学反应与热膨胀：放热反应或温度波动可能引起流体体积变化，从而导致超压。

外部因素

• 外力破坏（地震活动、自然灾害）：地震、滑坡或其他自然力可能对基础设施施加过大应力，导致压力骤升。

• 互联系统引起的压力波动：来自相邻系统（如压缩机站或互联管道）的压力波动可能导致压力意外升高。

• 操作失误：阀门位置设置错误、系统停机操作不当或压力设定错误等失误，可能导致危险的压力升高。

Overpressure can occur due to various operational and external factors. Understanding these causes is essential for implementing the right protection measures.

Operational and Process Causes

• Blockages or obstructions in pipelines: Debris, wax build-up, or hydrate formation can restrict flow, causing a rise in pressure.

• Malfunctioning valves or equipment failure: Pressure control valves that fail to open or close properly can increase uncontrolled pressure.

• Chemical reactions and thermal expansion: Exothermic reactions or temperature fluctuations can cause fluid volume changes, leading to overpressure.

External Factors

• External force damage (seismic activity, natural disasters): Earthquakes, landslides, or other natural forces can exert undue stress on infrastructure, leading to pressure spikes.

• Pressure surges from interconnected systems: Surges from adjacent systems, such as compression stations or interconnected pipelines, can unexpectedly increase pressure.

• Human errors in operational procedures: Mistakes in valve positioning, system shutdowns, or incorrect pressure settings can increase dangerous pressure.

有效的超压保护需要量身定制的解决方案，以应对油气行业各类作业中特有的风险。

• 生产作业：井下作业、水力压裂和气举系统等生产流程容易产生超压风险。在此类情况下，确保防喷器（BOP）和泄压系统正常运行，是维持安全作业的关键。

• 管道作业：集输及配气管道容易发生超压事件，尤其是由管道堵塞、设备故障或压力激增引起的超压。为降低此类风险，压力浪涌保护装置和自动切断阀是管道保护策略中的关键组件。

• 炼油与加工设施：在炼油厂中，蒸馏塔、反应器和换热器面临的超压风险最高。超压可能导致泄漏、火灾或爆炸，因此，火炬系统和放空系统等压力管理设施对于控制过高压力及防止系统故障至关重要。

• 液化天然气与海上作业：由于低温流体具有挥发性且系统结构复杂，液化天然气（LNG）设施面临着独特的超压挑战。海上平台（包括海底设备和井口装置）同样需要可靠的超压保护，特别是考虑到此类作业环境偏远且具有高风险性。

Effective overpressure protection requires tailored solutions that address the unique risks of various operations within the oil and gas industry.

• Production Operations: Production processes such as well operations, hydraulic fracturing, and gas lift systems are prone to overpressure risks. In these cases, ensuring that blowout preventers (BOPs) and pressure relief systems are properly functioning is key to maintaining safe operations.

• Pipeline Operations: Gathering, transmission, and distribution pipelines are vulnerable to overpressure events, particularly from blockages, equipment failure, or pressure surges. Surge protection devices and automatic shut-off valves are critical components of pipeline protection strategies to mitigate these risks.

• Refining and Processing Facilities: In refineries, overpressure risks are highest in distillation columns, reactors, and heat exchangers. Overpressure can result in leaks, fires, or explosions, making pressure management systems such as flare and blowdown systems vital in controlling excess pressure and preventing system failures.

• LNG and Offshore Operations: Liquefied natural gas (LNG) facilities face specific overpressure challenges due to the volatility of cryogenic fluids and the complexity of their systems. Offshore platforms, with their subsea equipment and wellheads, also require robust overpressure protection, particularly due to the remote and hazardous nature of these operations.

VERSA 气动/液压压力传感器（杆式先导阀）是超压保护系统中的常用组件。该压力传感器提供“三通切断与泄放（block and bleed）”型或“二通泄放、两位”型阀门配置。其设计旨在直接接收来自管线的高压信号。传感器内部的驱动弹簧可调节至特定的压力设定点；一旦压力超过该设定点，传感器即会动作，向系统控制阀发送信号，从而触发管线关断。

The VERSA pneumatic/hydraulic pressure sensor (stick pilot) is a common component of an overpressure protection system. VERSA’s Pressure Sensor is available in a 3-way block and bleed or a 2-way bleed, 2-position valve. The pressure sensor is designed to receive a high-pressure signal directly from the pipeline. The pressure sensor actuating spring can be adjusted to a pressure setpoint that, when exceeded, will cause the sensor to react. This signals the system control valve, facilitating a pipeline shutdown.

尽管 VERSA 压力传感器可作为独立组件提供，但压力传感回路通常还需要若干其他组件：

• 用于一级降压的高压调节器

• 用于二级降压的标准压力调节器

• 过滤元件

• 控制阀

• 压力传感器

VERSA 的 VMAP（模块化空气组件系统）可提供一套集成式组件包，其中包含了超压保护 (OPP) 系统所需的所有部件。VMAP OPP 是一种紧凑且易于安装的组件，由气体预处理、压力传感和控制阀这三个模块组成。

While the VERSA Pressure Sensor is available as a stand-alone item, a pressure sensor circuit generally requires several additional components:

• A high-pressure regulator for the first pressure stepdown

• A standard pressure regulator for the second stepdown

• Filtration elements

• Control valve

• Pressure sensor

VMAP, VERSA’s Modular Air Package system, can provide an integrated component package with all the required items for an Overpressure Protection (OPP) system. The VMAP OPP is a compact, easy-to-install assembly consisting of three modules: Gas Preparation, Pressure Sensing, and Control Valve.

气体预处理模块

该气体预处理模块配备高压过滤器，用于去除气体中的杂质；随后，气体经由两个调压阀调节至适合执行机构控制模块使用的压力。

经过过滤的高压气体与经过调压的低压气体均被输送至传感器模块。

Gas Preparation Module

The Gas Preparation Module has a high-pressure filter to clean the debris from the gas before regulating the pressure through two regulators to a suitable pressure for the actuator control module.

Both the filtered high-pressure gas and the regulated low-pressure gas are directed to the Sensor Module.

控制阀模块

控制阀模块（包括先导式或电磁式阀门）在先导供气管路（来自传感器模块）失压时会自动关闭。电磁式阀门还支持远程关闭操作。这两种阀门均可选配手动锁定复位功能，以及电磁阀或先导阀冗余配置，从而进一步提升安全性和可靠性。

传感器模块

传感器模块负责针对超压工况做出初始响应。当压力（高压供气）超过设定值时，其中的压力传感器会切断通往控制阀模块的先导气源（低压供气）。

VERSA 提供标准化的典型回路方案，并可根据需要进行功能扩展，例如增加截断放空阀（block and bleed valve）、泄压阀，甚至是低压传感器，以同时提供超压和欠压保护。VERSA 的解决方案可完全定制，以满足用户的具体需求。所有组件均经过现场验证，并获认证支持高达 SIL 3 的安全等级；此外，该方案还融合了“实际工况可靠性”（Real-World Reliability）解决方案的各项优势特性。

VMAP 超压保护（OPP）系统是一款在工厂完成组装与测试的解决方案，其创新设计最大限度地减少了管道和管件的使用。该方案减少了潜在的泄漏点，省去了大量与管道及管件相关的成本；同时，由于安装简便，人工成本也随之降低。

该解决方案完全采用 316 不锈钢材质，由单一供应商提供，从而消除了许多自动化控制系统中常见的材料交叉污染风险。

VMAP 超压保护系统充分体现了 VERSA 对“实际工况可靠性”的承诺——即提供坚固耐用、性能可靠的阀门，能够经受最严苛、最具挑战性的工况考验。

Control Valve Module

The Control Valve Module, either a pilot or a solenoid operated valve, will close if the pilot supply line loses pressure (from the sensor module). The solenoid operated valve can also be remotely operated to close the valve. Both valve types can be equipped with a manual latching reset functionality and/or solenoid or pilot redundancy for additional safety and reliability.

Sensor Module

The Sensor Module provides the initial reaction to an overpressure condition. The pressure sensor is responsible for shutting down the pilot supply (low pressure supply) to the control valve module when the pressure (high pressure supply) exceeds the set point.

VERSA offers standardized typical circuits that may be enhanced to include a block and bleed valve, relief valves, or even a low-pressure sensor to provide both over and under pressure protection. The VERSA solution can be fully customized to meet the user’s requirements. All components used are field-proven and certified for use up to SIL 3, further enhanced with features from our Real-World Reliability solutions.

VMAP Over Pressure Protection (OPP) is a factory-assembled and tested solution that minimizes the use of piping and fittings through innovative design. Several potential leakage points have been reduced, and many of the associated costs of tubing and fittings have been removed. This also results in lower labor costs due to the ease of installation.

This fully 316 stainless steel solution, sourced from a single vendor, also removes the risk of cross-contamination of materials that can be seen on many automation control systems.

The Over Pressure Protection VMAP is a true example of VERSA’s Real World Reliability commitment to providing durable and dependable valves that withstand the toughest and most challenging operating conditions.
