The 35-35 double gate hydraulic blowout preventer is composed of components such as a housing, oil cylinder, piston rod, and gate. It has a built-in oil circuit, making it relatively easy to replace the gate. The shell, oil cylinder and other components are made of alloy steel parts, and the material properties can meet their standards. The sealing between the oil cylinder and the housing is achieved through sealing components. The sealing components expand under the pressure inside the well, causing the rubber sealing components on their outer surfaces to tightly adhere to the housing and oil cylinder, thereby achieving sealing

After surface chemical treatment, the sealing surface of the gate chamber has improved surface hardness, increased wear resistance, and prevented scratching by the gate body. The sealing reliability of the gate is increased, and it can fully bear the weight of the cylinder head after opening, reducing sagging during opening and ensuring flexible opening and closing. The stamping chamber is designed as a rectangle with uniform stress distribution

When the wellhead needs to be closed for a long time, it can be manually locked after the wellhead hydraulic is closed to prevent the hydraulic system from depressurizing and affecting the closure. However, it should be noted that the wellhead cannot be opened with a manual locking device

The specific operation of the 35-35 double ram hydraulic blowout preventer is as follows:

1. When there are drilling tools in the well, it can seal the annular space between the casing and the drill pipe or between the casing and the tubing.

. When there are no drilling tools in the well, a fully sealed gate can be used to seal the well

2. In order to effectively control formation pressure, it can be used in conjunction with a well control choke manifold to achieve balanced pressure drilling

3. With a sealed wellhead, special operations such as well killing and flushing can be carried out

The main purpose of a hydraulic blowout preventer is to effectively control blowouts during drilling. The gate valve blowout preventer is equipped with a hydraulic control device, which can be used alone, in combination, or in combination with the annular blowout preventer
