Problems solved by technology
[0005] However, if there is an emergency situation where a sudden blowout on site requires well closure, and the accumulator group or pump group of the ground BOP control device accidentally causes insufficient fluid volume or pressure to provide power fluid for the control manifold, It will lead to failure to close the well in time and blowout, which will lead to major safety accidents

Embodiment Construction
[0025] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0026] see figure 1 As shown, the embodiment of the present invention provides a nitrogen backup system of the ground BOP control device, which is used to connect with the backup ball valve of the existing ground BOP control device, so as to prevent the accidental liquid flow of the ground BOP control device. Or when the pressure is insufficient to provide power fluid for the control manifold, emergency auxiliary energy is provided, and high-pressure gas is supplied through the nitrogen backup system as an emergency power source. The nitrogen backup system at least includes: relevant pipelines, nitrogen decompression valve 2, first group of nitrogen cylinder valves 3, second group of nitrogen cylinder valves 3a, first group of high-pre...

The invention discloses a nitrogen backup system for a ground blowout preventer control device, which belongs to the technical field of petroleum drilling well control. The system provides high-pressure gas as an emergency power source for the ground blowout preventer control device, including high-pressure nitrogen cylinders, valves, and related pipelines. The relevant pipelines of the nitrogen backup system include at least the first set of pipelines and the second set of pipelines. , the third group of pipelines, and the fourth group of pipelines. The first group of pipelines of the nitrogen backup system is sequentially provided with a nitrogen pressure reducing valve, a nitrogen cylinder valve, and a high-pressure nitrogen cylinder. The pipe is connected with the air inlet of the driller's console or the auxiliary console of the surface BOP control device. When there is an emergency on the site and the well needs to be shut down quickly, it can provide emergency auxiliary energy for the control manifold of the ground BOP control device, so as to avoid that the accumulator group or pump group of the ground BOP control device cannot provide power for the control manifold Major accidents such as blowouts caused by liquids.
Description
technical field [0001] The invention relates to the technical field of petroleum drilling well control, in particular to a nitrogen backup system of a ground blowout preventer control device. Background technique [0002] The surface blowout preventer control device is an important equipment for controlling the wellhead blowout preventer group, hydraulic throttle valve and well kill valve in oil and gas drilling, and is the necessary safety equipment for preventing blowout in drilling operations. [0003] The prior art ground BOP control device is mainly composed of remote console, hydraulic pipeline, driller's console or auxiliary console, and air pipe cable; the driller's console or auxiliary console is usually installed on the ground BOP control It is installed on the drill floor, so that the driller can easily realize the remote control of the remote console. The remote console is composed of a base, a fuel tank, a pump group, an accumulator group, a control manifold, v...
