Helium Gas Seal Testing System for Casing and Tubing Sets a New Industry Benchmark
In the field of oil and gas development, tubing and casing serve as the “lifeline” of wellbore safety. The sealing integrity of their threaded connections directly determines the safety and efficiency of drilling operations, as well as the economic benefits of hydrocarbon production.
With the advancement of development in complex blocks such as ultra-deep reservoirs, shale gas, and high-sulfur gas wells, the shortcomings of traditional nitrogen pressure decay methods—such as insufficient detection accuracy, low efficiency, and limited application scenarios—have become increasingly prominent. Consequently, there is an urgent demand in high-end well sites for sealing detection technologies that offer precision, efficiency, and high-pressure adaptability.
Leveraging its core technological accumulation and deep industry experience, Wingoil has developed a high-end Tubing and Casing Helium Seal Test System. This system utilizes high-pressure capabilities to solve sealing challenges, building a solid defense line for the safe production of oil and gas fields.

Addressing Industry Pain Points, Reshaping the New Paradigm of Seal Testing
In oil and gas field operations, the risk of thread leakage often lurks within multiple uncontrollable factors such as transportation impacts, non-standard operations, improper torque application, and aging working conditions. Once a leak is missed during inspection, it can easily trigger major accidents like blowouts or oil and gas leaks, resulting in substantial economic losses. Traditional testing methods struggle to overcome three core bottlenecks:
Inefficiency: A single test cycle can take 30–60 minutes, dragging down construction progress.
Lack of Precision: They can only determine if a leak exists, but cannot pinpoint the leak location or provide quantitative analysis.
Insensitivity: Sensitivity drops sharply under complex conditions like high pressure and salt spray, making it difficult to meet the requirements of ultra-high pressure well sites.
Targeting these industry pain points, Wingoil has deeply integrated helium tracer technology with high-pressure equipment R&D to launch the Tubing and Casing Helium Seal Test System, completely overturning traditional testing logic.
The system utilizes a mixed medium of 90% nitrogen and 10% helium. Leveraging helium’s high molecular permeability, it can precisely capture micro-leakage channels. Combined with high-sensitivity detection units and a scientific process flow, the system achieves rapid leak location and quantitative analysis of leak rates. Furthermore, the single test cycle is compressed to just 5–15 minutes, improving efficiency by over 60% and providing core support for efficient on-site operations.
Core Technology Empowers High-Pressure Testing Capabilities
As a professional manufacturer specializing in high-pressure and ultra-high pressure testing products, Wingoil relies on a team of experts in machinery, automation, and petroleum extraction. By integrating advanced German technology and craftsmanship (from Maximator), we have created a detection system that excels in high-pressure adaptability, precision, efficiency, and reliability. Our core advantages are fully demonstrated below:
Ultra-High Pressure Adaptability for Full-Scenario Operations:
The system delivers a maximum output pressure of up to 150 MPa, with stable routine testing at 70 MPa. It easily adapts to diverse scenarios, including conventional gas wells, ultra-high pressure gas wells, and shale gas wells. The pressure regulation precision reaches ±0.5 MPa, supporting segmented pressurization and stable pressure-holding control, perfectly meeting the sealing detection requirements of high-pressure operations in complex blocks.Adopting a mixed pneumatic-hydraulic drive mode, the system is intrinsically safe and requires no additional explosion-proof design. With an IP54 protection rating, it operates stably in harsh wellsite environments—ranging from -15℃ to +40℃, in conditions of humidity, salt spray, oil mist, and mold—making it suitable for both inland oilfields and offshore platforms.
Dual-Booster Technology Route for Flexible Adaptation:
To meet diverse operational needs, the system offers two core technical routes: pneumatic booster pumps and liquid booster pumps.
Pneumatic Booster Pumps: Feature full pneumatic control, superior explosion-proof performance, and stable pressure boosting without overshoot. They isolate power from the test medium to prevent cross-contamination, making them ideal for high-precision detection in land-based oilfields.
Liquid Booster Pumps: Offer higher efficiency and lower noise, making them suitable for offshore platforms and large-scale operations.
We provide precise matching of the optimal solution based on the client’s specific working conditions.
Precision Configuration for Unmatched Detection Accuracy:
The system is equipped with the UK INFICON Protec P3000XL Helium Leak Detector, boasting a detection precision of 1×10⁻⁷ mbar·l/s and a sensor response time of just 450ms. Paired with a clamp-ring helium collection sleeve, it effectively prevents helium escape, further enhancing detection sensitivity.All core components undergo rigorous calibration. The system includes a 5T hydraulic winch with stepless speed regulation and overload protection, along with inflatable packers that adapt to different casing specifications. The sealing pressure perfectly matches the system’s high pressure, ensuring test results are accurate and reliable.
Compliance & Quality Endorsement: Deep Industry Roots Demonstrate Brand Strength
Wingoil consistently leads product development with high standards. The entire process—from system design and manufacturing to inspection—strictly adheres to core domestic and international standards such as SY/T 6872-2012, GB/T 21267-2024, and API SPEC 5CT. We can also obtain authoritative certifications like BV, DNV, and CCS according to client requirements, ensuring full compliance with the regulatory demands of high-end well sites.
Featuring a skid-mounted integrated design, the system is easily disassembled, lifted, and rapidly assembled on-site. This allows for multi-wellsite deployment, significantly reducing equipment relocation costs.
Relying on superior product quality and professional technical solutions, Wingoil’s high-pressure testing equipment is widely used by major enterprises including CNPC and Sinopec. We have successfully delivered projects for benchmarks such as Sinopec International Petroleum Service Corporation and Jiangsu Oilfield Company. Our performance in sealing detection under ultra-high pressure and complex conditions has earned high recognition within the industry.
Forward-Looking Layout for the Future: Empowering Green and Efficient Oil & Gas Development
Facing the industry trends of “efficiency, energy conservation, and intelligence,” Wingoil continuously iterates its technical solutions. We are actively exploring supporting processes such as on-site PSA nitrogen generation integration and helium recovery and purification. These innovations can achieve a helium recovery rate of over 85% and reduce medium consumption costs by 30%-40%, effectively balancing economic benefits with environmental protection.
In the future, the company will further promote the deep integration of testing equipment with IoT technology. This will enable real-time data uploads, remote monitoring, and trend prediction, constructing a full-life-cycle seal management system of “Detection – Optimization – Improvement.”
From conventional well sites to ultra-high pressure complex blocks, and from factory acceptance testing to on-site operation testing, Chongqing Wingoil Technology takes high-pressure technology as its core and precision detection as its soul, guarding the safety production line of oil and gas fields with professional equipment. In the future, Wingoil will continue to deepen its roots in the high-pressure testing field, driving industry upgrading through technological innovation and injecting strong momentum into the high-quality development of domestic oil and gas field exploration!
