Collecting and switching device for oil and gas of underwater wellhead

Abstract

A collecting and switching device for oil and gas of an underwater wellhead comprises an oil control cover, a quick crossover coupling, an anti-settling baffle and a sinking structure, wherein the quick crossover coupling is arranged on the top of the oil control cover; the anti-settling baffle is arranged on the bottom of the oil control cover; the sinking structure is arranged on the bottom of the anti-settling baffle; the quick crossover coupling comprises a gate valve, a stand pipe, a plurality of bevel gear sealing devices, a funnel-shaped structure and a hose coupling; the stand pipe is arranged on a port of the upper portion of the gate valve; the bevel gear sealing devices surround the stand pipe; the funnel-shaped structure is connected to the stand pipe; the hose coupling penetrates in the funnel-shaped structure and is connected with the quick crossover coupling; and the hose coupling is provided with a gripping handle which is matched with a manipulator of an underwater robot. When a leaking accident occurs, a leaking point can be fastened by the collecting and switching device rapidly and effectively; after a pipe of the leaking point is switched, leaked oil or gas can be delivered to an offshore engineering ship through an oil or gas delivery pipe; the problem that loss and marine pollution which are caused by oil or gas leakage is solved; and safety of marine petroleum exploitation engineering is guaranteed.

Description

technical field [0001] The invention relates to an oil and gas control device for oil leakage, in particular to a collection transfer device for underwater wellhead oil and gas. It belongs to the field of offshore oil engineering. Background technique [0002] Oil spills, oil spills, and oil spill accidents in the world's oceans are increasing unabated due to various reasons, and the pollution and damage to the marine ecological environment are also serious and long-term. Although the pollution caused by marine accidents is only a small part of marine oil pollution, due to the sudden occurrence of marine accidents and the high degree of harm, it is necessary to establish a marine emergency oil spill emergency response system and reasonably configure oil spill emergency environmental protection equipment And dispatch the forces of all parties to quickly and efficiently deal with oil spill accidents at sea, and reduce the losses and pollution to the ocean caused by oil spills...

AI Technical Summary

Problems solved by technology

[0005] The main purpose of the present invention is to overcome the above-mentioned shortcomings existing in the prior art, and to provide an underwater wellhead oil and gas collection transfer device, which can not only quickly and effectively hold the leakage point when a leakage accident occurs in offshore oil and gas exploitation ; Moreover, after switching the pipeline at the leak point, the leaked oil and gas are transported to the engineering ship on the sea surface through the oil and gas pipelines, which solves the loss caused by oil and gas and the damage to the ocean. Pollution problems; provide safety guarantee for offshore oil exploitation projects
