Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] refer to figure 1 It is a structural schematic diagram of an embodiment of the oil control and diversion device. When a blowout occurs in deep water oil and gas exploitation activities and the original blowout preventer group on the seabed fails, refer to Figure 6 The fixed base 19 is lowered to the bottom of the sea. When the fixed base 19 support frame base 10 is installed on the guide frame of the original failure preventer group 18, the hydraulic medium enters the hydraulic cylinder 14, and the hydraulic cylinder 14 is pushed to drive the guide rail block 11 and the clamping disc 5 to move. The clamping disc 5 is clamped on the top of the original failure preventer group 18, and the installation of the fixed base 19 is completed.

[0027] refer to Figure 7 The oil control dome 2 and the blowout preventer 1, the injection pipe and the inje...

Abstract

The invention relates to an oil control guiding device for marine oil and gas blowout. The oil control guiding device comprises an oil control guiding cover, a fixed base, an electromagnetic locking device, a guide rail device, a blowout preventer and the like. The fixed base is placed in the seabed in a descending mode, and a clamping disc on the fixed base is quickly clamped on the upper portion of an original ineffective blowout preventer unit through a hydraulic device. The oil control guiding cover and the blowout preventer are guided by a guide rope and placed in the seabed in a descending mode through a drill rod or a marine riser, and meanwhile the electromagnetic locking device is powered on through an underwater battery module installed on the oil control guiding cover. When the oil control guiding cover makes contact with the fixed base, the electromagnetic locking device is powered off, locking plugs are plugged into locking clamping jaws through reset springs, and then the oil control guiding device is installed, injectant connectors are connected with an external injection pipeline, and an inducer and a hydrate inhibitor are injected to increase oil receiving amount and prevent generation of hydrate. When blowout occurs in the deepwater drilling process, the device can quickly control leaked oil and gas and guide the leaked oil and gas to a sea surface oil receiving ship, when the sea surface oil receiving ship evacuates in emergency due to the severe sea state, a leakage opening is quickly closed, and therefore environmental pollution caused by leakage of oil and gas is reduced, and waste of oil and gas resources is reduced.

Description

technical field [0001] The invention relates to the field of marine oil and gas emergency equipment, in particular to a rapid positioning electromagnetic locking oil control and diversion device for marine oil and gas blowouts, which is suitable for on-site emergency disposal of seabed oil spill accidents. Background technique [0002] Blowout accidents during deep-water oil and gas exploration and development will not only cause huge casualties and property losses, but also cause major environmental pollution. my country's petroleum industry is moving towards the deep water in the South China Sea. Research on deep-water blowout emergency equipment is of great value for the safe development of oil and gas in the South China Sea. The oil control and diversion device is an emergency equipment for blowouts in offshore oil and gas exploration and development. Waste of oil and gas resources. [0003] Requirements for emergency equipment for deep-sea oil and gas exploration and d...
