Problems solved by technology

When the blowout preventer needs to be closed in an emergency situation on site, if the rotary valve of the blowout preventer control device is not pulled in time, the blowout preventer cannot be closed, and in serious cases, a blowout accident will occur, resulting in immeasurable losses
At the well site, the reliability of the operation of the driller's console is poor. When the blowout preventer needs to be closed, it is easy to happen that the driller's console fails to control the rotary valve on the remote console for reversing operation.

Abstract

The invention provides a driller console, a gas source conversion manifold and a gas supply system, the driller console comprises a driller control manifold, a first gas source, a second gas source and a gas source conversion manifold, and the gas source conversion manifold comprises a first pipeline, a second pipeline and a third pipeline; the first gas source is connected with the first end of the first pipeline, and the second end of the first pipeline is connected with the gas inlet end of the driller control manifold; the second gas source is connected with the first end of the second pipeline, and the second end of the second pipeline is connected with the gas inlet end of the driller control manifold; and the second pipeline is provided with a pneumatic control reversing valve used for controlling connection and disconnection of the second pipeline. The first end of the third pipeline is connected with the first gas source, and the second end of the third pipeline is connected with a valve position control port of the pneumatic control reversing valve. According to the driller console, the operation reliability of the driller console in a blowout preventer control device is improved.

Description

technical field [0001] The invention relates to the technical field of oil and gas drilling equipment, in particular to a driller's console, a gas source conversion manifold and a gas supply system. Background technique [0002] The switch action of the blowout preventer in the drilling operation is controlled by the blowout preventer control device; under the control of the blowout preventer control device, the blowout preventer can control and prevent well kick and blowout, ensure drilling safety, and prevent blowout The controller control device is the key equipment in the drilling operation. [0003] Air-operated BOP control device is a widely used BOP control device. The air-operated BOP control device is usually equipped with a driller's console and a remote console. By operating the pneumatic valve handle on the driller's console, the compressed air can enter the cylinder on the remote console through the pneumatic valve, and then Push the rotary valve on the remote...
