Oil Fields Wear Resistant 300PSI Rubber Sealing Molding Part

Wear-Resistant And Pressure-Resistant Polyurethane Coiled Tubing Sealing Box Rubber Core Used In Oil Fields

Description:

When the oil field enters the later stage of development, there will often be a problem of reduced production. Generally, the sidetracking method of old wells can be used to extract the remaining oil.

The use of coiled tubing underbalanced drilling technology can not only quickly sidetrack small boreholes, but also effectively protect the reservoir, thereby improving the development benefits of old oilfields.

When performing coiled tubing underbalanced drilling operations, a wellhead sealing device—the blowout preventer is needed.

Its function is similar to the rotary blowout preventer used in conventional drill pipe underbalanced drilling, but there are differences.

The blowout preventer is a well control device located between the injection head and the blowout preventer group.

The piston is pushed by hydraulic pressure, the rubber core is squeezed, and the coiled tubing rubber core is firmly wrapped on the surface of the coiled tubing, and it is inserted under the coiled tubing. Sealing is achieved in the well or when exiting from the well.

In the process of underbalanced drilling, it works with the choke manifold to adjust the wellhead back pressure and jointly maintain the stability of the bottom hole pressure, so as to realize the underbalanced environment of drilling and blowout.

Coiled tubing workover and other work under pressure At the time, the wellhead is sealed by the blowout preventer to ensure the safety of operation.

The rubber core is an important part of the blowout preventer.

The rubber core produced by our company is made of imported polyurethane raw materials and molded.

The surface of the product is smooth and flawless. The teeth are in good agreement with each other.

The 55,000 meters of coiled tubing is in the hole seal.

Through, the dynamic sealing pressure is 3-35Mpa, if fracturing is carried out,it can withstand the static sealing pressure of about 70Mpa.
