Description

China Vigor Drilling Oil Tools And Equipment Co., Ltd. is one of the most professional manufacturers and suppliers of Vigor Tubing Retrievable Safety Valve(VTRSV) in China, featured by competitive price and fast delivery. Welcome to buy high quality Vigor Tubing Retrievable Safety Valve(VTRSV) in stock here from our factory.

Vigor Tubing Retrievable Safety Valve(VTRSV) is a kind of tubing retrievable safety valve that is controlled at the surface. It directly connects to the tubing string. There is a hydraulic control line connecting to the safety valve from the ground. While a certain amount of pressure is supplied through this control line to the safety valve, the valve remains open; while the pressure is released, the safety valve will close and the tubing pass is closed at the same time.

Serving as a critical and mandatory risk reduction component on both onshore and offshore production wells, the normally full-bore inline valve directly threads as an integral section into the overall tubing string deployed downhole. It incorporates an active surface-controlled closure mechanism normally kept open by applying hydraulic pressure via a control line running from the wellhead to the sub-surface location of the TRSV valve.

vTRSV Series Tubing Retrievable Safety Valve

VTRSV-FT Tubing Retrievable Safety Valve

VTRSV-FT tubing-retrievable safety valve is a flapper-type, hydraulically operated TRSV installed in the production string. It is designed to shut in a well in case of an uncontrolled surface or subsurface event. The valve is held open by the hydraulic control pressure and remain open until the control pressure is released. The robust hydraulic piston provides a reliable control system and isolate the inner critical part from the well fluid.

VTRSV-FT utilizes a metal-to-metal body joint and metal to metal flapper & seat to provide a superior well containment. An optional self-equalizing feature allow the pressure drop before the flapper start to open and prevent flow directly across the critical MTM seal interface. VTRSV-FT can be permanently locked open by a lock-out tool, and establish a communication path between the TRSV hydraulic chamber and tubing string for a wireline retrievable insert valve.

VTRSV-SRP Tubing Retrievable Safety Valve

VTRSV-SRP tubing retrievable safety valves are designed with single rod-piston actuation and flapper type closure mechanism. The valve is held open by the hydraulic control pressure and remain open until the control pressure is released. The non-elastomer piston seal with back-up system are provided for better dynamic and static seal.

VTRSV-SRP body joints features reliable metal to metal seal, and the spherical metal to metal seal is also used between the flapper and seat. Additional metal to metal piston seal in full closed position is designed for minimizing the potential leak paths. The self-equalizing feature provides an equalizing flow path around the flapper mechanism. This flow path allows the pressure drop and prevents flow directly across the critical MTM seal interface.

If necessary, the VTRSV-SRP can be permanently locked open by a lock-out tool, and an additional communication tool can establish communicated path between the TRSV hydraulic chamber and tubing string before installing a wireline-retrievable insert valve.

VTRSV-CFT Tubing Retrievable Safety Valve

VTRSV-CFT is a single rod piston, curved-flapper type, tubing retrievable safety valve engineered to provide a reliable operation and long-term life in a hostile environment. The valve utilizes the non-elastomeric single piston actuator, metal to metal body joint, a rugged flapper-closure mechanism, centralizing system to provided 100% well containment when closed. For maximum reliability, the piston mechanism incorporates static metal to metal stop seals while the piston reaches full open and full close positions.

The slim line curved flapper design is utilized to optimize O.D. and I.D. of the valve for maximal production rate and smaller casing size. An industry-standard self-equalizing feature can be added to this valve. It allows the pressure drop before the flapper start to open and prevent flow directly across the critical MTM seal interface.

VTRSV-CFT can be permanently locked open by a lock-out tool, meanwhile a communication path will be established between the TRSV hydraulic chamber and tubing string to control a wireline retrievable insert valve.

Features and Benefits

Excellent gas ability.

Wireline-Retrievable Safety Systems

VWRS Vigor Wireline Retrievable Flapper-Type Safety Valves

VWRS Vigor Wireline Retrievable Safety Valves is a flapper-type, hydraulic operated WLRSV. The valve's function is similar to a tubing retrievable safety valve. It need be assembled with a lock mandrel and install the combination assembly in a safety valve landing nipple or disable TRSV which already communicated. It is typically used in a dual-string well where the annular space is not enough to accommodate a TRSV. Or it can be used as a secondary insert vale in a disabled TRSV. The valve features a closure mechanism with a full metal to metal seal plus a secondary soft-seal, this allows for maintaining a good sealing under any scale of gas pressure. The valve has a self-equalizing mechanism. While the hydraulic pressure actuates the piston and opening prong downward movement, the secondary metal to metal seat will be unseated and allow the below pressure to enter through equalizing port prior to opening.

Features and Benefits

Larger flow through I.D. design.
Build-in Self-equalizing mechanism.
Spherical metal to metal seal between flapper & seat.
Pump-through capability. Isolate and protect the internal critical component at the opening position.

Easy to retrieve by slickline.
Compatible with top no-go or selective lock mandrel.
Deep-set capability, ultra-strong spring ensure smooth and reliable closure.
Pressure rating up to 15,000 psi.

Key Benefits of TRSV

1. Rapid Well Shut-In Ability

Vigor Tubing Retrievable Safety Valve(VTRSV) allows offshore platform operators to swiftly shut-in well production flow as an emergency safety response to near well or process upsets through its surface-controlled hydraulic actuation mechanism. This averts the risk of uncontrolled hydrocarbon discharge through simple valve closure, safeguarding personnel, and assets, and preventing environmental contamination.

2. Securing Well Integrity

In events of catastrophic damage or operational failure at the wellhead and surface production setups, the sub-surface VTRSV location secures wellbore integrity independently through autonomous closure on control line depressurization. This contains well fluids when surface well control equipment is rendered inoperable.

3. Enabling Intervention without Rigs

The functionality of Vigor Tubing Retrievable Safety Valve(VTRSV) systems allows deliberate opening/closing to conduct basic wellbore interventions like changing completion components without requiring expensive coiled tubing or wireline rigs. This reduces workover project timelines and costs.

4. Retrievable while Keeping Well Live

Being tubing retrievable, the valve permits pulling tubing strings for maintenance or changes whilst keeping the well live, eliminating the need for well-killing or permanent plugging operations.

5. Compliance with API 14A Standard

Vigor Tubing Retrievable Safety Valve(VTRSV) is manufacturable according to API 14A specifications covering design, material, testing, and quality control requirements for subsurface safety valves. This ensures suitability for oil/gas well usage globally. Optional monogramming certifies compliance.

Applications

1. Industry Usage

As an integral and mandatory tubing safety component, TRSSSV systems see extensive worldwide usage securing offshore shallow and deepwater wells. Regulations globally mandate sub-surface safety valves as prerequisite risk reduction well equipment.

2. Common Tubing Sizes

With standardization for intercompatibility, TRSSSV products are available covering the entire range of regular tubing dimensions used in offshore fields.

Valve sizes typically vary from 2-3/8" to 5-1/2" O.D. corresponding to normal tubing diameters run in most offshore hydrocarbon completions. The inline full-bore construction allows suitable pairing with common EUE, VAM, NUE, or other API tubing connections as dictated by well architecture and depths.

Customization is also possible to suit well-specific tubing lengths, O.D., and connection configurations, inclusive of standard or proprietary API threads. This enables a TRSSSV selection fully adapted for each well duty.
