The blowout preventer is to prepare and store a sufficient amount of pressure oil in advance to control the flow direction of the pressure oil. It is good at blowout preventers and hydraulic valves to make them open and close quickly. Hydraulic pressure drop after hydraulic oil consumption.
When it reaches a certain level, the control device will automatically replenish the storage, so that the hydraulic oil is always kept within the high-pressure range.
The ground BOP control device is mainly composed of the following components.
1. Remote console
2. Driller's Console, Auxiliary Driller's Console
3. Air duct cable
4. Hydraulic pipelines (including pipelines such as hose pipelines or pipeline brackets).
The remote operation panel is composed of fuel tank, pump group, accumulator group, pipe bundle, various valve components, instruments and control box, etc. The main function of the remote console is to generate high pressure control from the pump unit
liquid and stored in the accumulator unit. When it is necessary to open and close the sprinkler, the high-pressure control fluid from the accumulator is distributed to each control object (sprinkler) through the three four-way valves connected to the piping.
Drill consoles are usually mounted on the drill floor and allow the drill to conveniently operate the sprinklers remotely.
Air cables are used to connect the air path between the remote console and the drilling console. The pipeline cable is composed of a sheath and multiple dies, with connecting flanges at both ends, respectively connected to the remote control
table and drill console connection.
Usually, the distance between the remote console and the wellhead blowout preventer group is 40m, and they need to be connected through a series of hydraulic pipelines. The connection methods include hard wire connection and hose line connection.
Hard lines include pipe racks, active lines, etc. The use of hard pipeline connections has advantages such as reliability, but has the disadvantage of inconvenient assembly. The hose connection has the advantages of simplicity and convenience, but in use note its flatness.
The working process of the air-controlled control device can be divided into three parts: the manufacture of hydraulic energy: the adjustment of storage and supplementary pressure oil and the control of its flow direction; the remote operation of air pressure.
Guangzhou Dongsu Petroleum D&E Equipment Co., Ltd. is one of the earliest professional manufacturers of surface-mounted BOP control system in China. Since the early 1980s, The company is committed to the development, design, research and development of surface-mounted BOP Control System, Pneumatic Pressure Test Unit, Choke Manifold Control Panel，etc. In 2017, we established a technical service training center integrating after-sales training, maintenance, testing and transformation to provide high-quality and efficient services.
