In recent years, China's oil and gas exploration and development has become increasingly advanced, encountering geological conditions that are becoming more complex and generally featuring deep reservoirs, high temperatures, and high production rates, as well as containing hydrogen sulfide and carbon dioxide corrosive gases. These acidic gas deposits cause severe corrosion to the equipment on the well site and require equipment that can withstand high impact wear. Conventional wellhead devices are difficult to meet these oil and gas production requirements. Materials used for high-sulfur-resistant wellheads are all special corrosion-resistant materials and adopts super nickel-based alloy flow channel welding technology. They use full-metal sealing devices suitable for high-pressure, corrosion-resistant, and harsh working conditions, which maximizes the safety of the wellhead operation. With super nickel-based alloy flow channel welding technology, hard-surface spraying technology, and polishing technology, 140Mpa gas-tight sealing can be achieved, and a true full-metal sealing device can be used for high-pressure, corrosion-resistant, high-displacement, and sand-proof working conditions. Equipped with a safety valve and wellhead control cabinet, the well can be shut down within 5 seconds at the fastest, maximizing the safety of the wellhead operation.

WELLHEAD CHRISTMAS TREE EQUIPMENT Wellhead Oil Recovery Medium and high-end wellhead equipment and manifolds
High-sulfur-resistant BOP Stack High-sulfur oil and gas fields in Southwest China, and Kazakhstan Reference standards:API 16A,GB/T 20174 Suitable for environments with high sulfur content, such as land and offshore platforms, which have special requirements for the anti-sulfur performance of the BOP stack. The inner cavity of the equipment that contacts the well fluid is welded with high sulfur resistance alloys. Key non-metallic sealing components, such as the rubber core and side door seal, that come into contact with well fluids are made of special materials suitable for high sulfur content environments. Inconel is done by using imported equipment and assisted by sophisticated testing and monitoring methods to ensure product quality. Product Applicability: For well control operations under high-sulfur conditions, the BOP stack has a corrosion resistance meeting the requirements for resistance to high hydrogen sulfide, and is suitable for occasions with hydrogen sulfide content ≥ 35%, equivalent to the HH level hydrogen sulfide in API 6A. ≥35% Suitable for occasions with hydrogen sulfide content 138MPa Rated working pressure: ram preventer 177ºC Highest temperature level WELL CONTROL BOP STACK EQUIPMENT Product Features Technical Parameters Nominal diameter 179.4-679.45mm (7 1/16″-26 3/4") 13.8-138Mpa (2000-20000psi) Recommended operating pressure 10.35Mpa(1500psi) Temperature Ratings for Metallic Materials Ram BOP Highest T-20/350 Annular BOP Highest T-20/250 Temperature Ratings for Non-Metallic Sealing Materials Ram BOP Highest BFF Annular BOP Highest BBD Performance level PR2 Sulfur resistance Level Applicable H2S Content:≥35% (API 6A HH level) Rated working pressure of hydraulic control system 20.7Mpa(3000psi) Rated working pressure
