Abstract

The invention provides an emergency oil control device used for leakage of offshore oil and gas marine risers. The emergency oil control device comprises an oil control cap main body, a quick crossover sub, sealing devices for cap body-marine riser, an adjustable support body for the sealing devices, mud mats and mud penetrating slabs; upper ends of F-shaped connecting pieces in the adjustable support body of the sealing devices are in rectangular guideway-type connection with a support body connecting steel plate in the oil control cap main body to form guideways of support steel plates witharched holes, so that the movement requirements of the support steel plates are met; the four support steel plates with the arched holes are hinged with each other; an included angle between every twosupport steel plates can be properly adjusted so as to enable the support steel plates to meet the angle error of a bent marine riser; a corresponding marine riser is encircled by rectangular sealingsteel plates with semicircular holes in each sealing device for cap body-marine riser, wherein the semicircular hole diameter is equal to the pipe diameter of the marine riser; and end parts of sealing rubber rings at front ends of the rectangular sealing steel plates with the semicircular holes are meshed and compressed, thereby realizing a function of sealing the marine risers different in pipediameter.

Description

technical field [0001] The invention relates to a seabed emergency oil control device, in particular to an emergency oil control device used for leakage at marine oil and gas risers. Background technique [0002] With the accelerated aging of the offshore oil exploitation process and approaching the service life, the oil spills, oil spills, and oil spill accidents in the offshore oil development have also increased. Marine oil and gas leakage accidents will cause serious and long-term pollution damage to the marine ecological environment. Countries around the world are paying more and more attention to the rescue of marine oil and gas leakage. To this end, it is necessary to establish an emergency rescue system for marine oil and gas spills, rationally allocate oil and gas oil spill emergency equipment and dispatch all forces, quickly and efficiently carry out offshore oil spill rescue work, and minimize the losses caused by oil and gas spills and marine pollution. lowest. ...
