•The construction of high-production oil and gas fields depends heavily on ultra-deep well drilling operations, which involves complex working conditions such as ultra-high pressure and high temperature. Well control equipment such as large-diameter blowout preventer stacks and manifolds for ultra-high-pressure, and high-temperature conditions are required for drilling large boreholes and installing multiple casings.
For ultra-deep well drilling with ultra-high-pressure, and high-temperature conditions, we provide blowout preventer and pipe manifolds including 175MPa (25000psi) ram preventer, 140MPa (20000psi) blowout preventer stacks, 105MPa (15000psi) blowout preventer stacks, 21 1/4-10000psi large diameter blowout preventer stacks for high pressure condition, 26 3/4"-3000psi large diameter ram preventer, 29 1/2"500psi and 30"1000psi diverter as well as high temperature seals up to BFF (350°F/177°C).

The bonnet is connected with the shell by jaw chunk, the packing element is taper type, and the sealing parts are exchangeable with imported products Product Applicability: Deep, Ultra-deep wells are mined with high formation pressure, should use ultra-high pressure BOP stack to ensure well control safety Manufacturing Standards: API 16A, GB/T 20174 WELL CONTROL BOP STACK EQUIPMENT Technical Parameters Nominal diameter 279.4mm (11″) Rated working pressure of hydraulic control system 20.7Mpa(3000psi) Recommended operating pressure 10.35Mpa(1500psi) The pressure of hydrostatic proof test Ram BOP 207MPa (30000psi) Annular BOP 155.25MPa (22500psi) Rated working pressure Ram BOP 138MPa (20000psi) Annular BOP 103.5MPa (15000psi) Temperature Ratings for Metallic Materials Sulfur resistance level Ram BOP Highest T-20/350 Annular BOP Highest T-20/250 Temperature Ratings for Nonmetallic Sealing Materials Ram BOP Highest BFF Annular BOP Highest BBD Performance level PR2 NACE MR0175
