Custom Specialized Expertly Designed Rubber BOP Parts For Wellhead Pressure

Product Specification

________________________________________

Product overview:

The spherical rubber core of the annular blowout preventer is the core component of the annular blowout preventer in oilfield drilling operations. It is mainly used to seal the wellhead in emergency or normal situations during drilling to prevent drilling fluid or high-pressure fluids such as oil and gas from spraying out of the wellhead. The spherical rubber core has a unique design and can deform evenly when under pressure, adapt to changes in wellhead pressure, and provide excellent sealing performance. It can effectively seal the wellhead under various complex working conditions, such as the passage of drilling tools of different sizes, empty wells without drilling tools, etc., and can prevent blowout accidents.

Structural composition:

1. Rubber body: Made of specially formulated rubber material, it has good elasticity, wear resistance and corrosion resistance. The rubber body has a spherical structure, which can better adapt to drilling tools of different shapes and sizes. When sealing, it can evenly fit the surface of the drilling tool to form a reliable sealing effect. The rubber material has been specially treated to withstand high temperature, high pressure, and erosion by drilling fluid, oil and gas and other media, ensuring long-term stable operation in harsh working environments.
2. Metal skeleton: embedded inside the rubber body, providing the necessary support strength for the spherical rubber core. Made of high-strength alloy steel, it has undergone precision machining and heat treatment. It can prevent the rubber from being damaged due to excessive deformation when the rubber core is subjected to high pressure, and at the same time ensure that the rubber core maintains a stable shape and performance during repeated use.
3. Sealing lip: located at the inner edge of the spherical rubber core, it is the part that directly contacts the drill bit to achieve sealing. The sealing lip has been specially designed and processed to have good fit and sealing performance. When subjected to hydraulic pressure, the sealing lip can tightly wrap the drill bit to form an effective sealing barrier to prevent fluid leakage in the well.

Working principle:

The work of the annular blowout preventer spherical rubber core produced and sold by our company Huichi petro depends on the drive of the hydraulic system. When the wellhead needs to be closed, the hydraulic oil enters the piston chamber of the rubber core through the hydraulic control system of the annular blowout preventer, pushing the piston upward. The piston drives the spherical rubber core to move upward together, while squeezing the rubber core to cause radial deformation. As the rubber core deforms, the sealing lip gradually shrinks toward the center, tightly hugging the drill bit or closing the wellhead, thereby sealing the wellhead. When the wellhead needs to be opened, the hydraulic system releases the hydraulic oil in the piston chamber, and the piston moves downward under the action of the return spring, the rubber core returns to its original state, and the wellhead is reopened.

Product Features:

1. Good sealing performance: The spherical rubber core is made of high-strength material and has good high-pressure resistance and wear resistance. When an oil well erupts, even if the drill bit has a certain eccentricity or irregular shape, the spherical rubber core can expand rapidly, achieve reliable sealing through its own elastic deformation, and effectively prevent the leakage of high-pressure fluid in the well.
2. Easy to operate: With the help of hydraulic system control, the response speed is fast. The operator only needs to control the switch of the hydraulic valve to achieve the closing and opening operation of the wellhead in a short time, and easily complete the action control of the spherical rubber core.
3. Long service life: Made of high-quality rubber material and high-strength metal skeleton, it has undergone strict quality inspection and performance testing, and has good wear resistance, corrosion resistance and fatigue resistance. Under normal use and maintenance conditions, it can withstand multiple sealing and opening operations, has a long service life, and reduces the replacement cost and maintenance workload of the equipment.
4. Strong adaptability: It can not only seal drilling tools of various sizes, but also achieve full closure of the wellhead in the case of an empty well without drilling tools. At the same time, it can adapt to harsh drilling operating environments such as high temperature, high pressure, and high sulfur content.
