Abstract

The invention provides a method and apparatus for measuring and determining motion law of spilled oil on water surface in lab and belongs to the technical field of offshore oil engineering. According to the embodiments of the invention, the method herein involves a spilled oil test simulation and measurement system. The method can simulate oceanic hydrodynamic force environment and oil spilling conditions of submarine pipelines, analyzes the images of oil spilling on water surface that are acquired by an image acquiring device and obtains moving patterns of the oil film on water surface under different hydrodynamic forces, so that the method can make accurate estimation of the track of the spilled oil on water surface and spilling range of the spilled oil, provides timely and accurate information for handling oil spilling incident, and provides scientific basis and reference for emergency decision-makers who can adopt timely and accurate anti-oil spilling measurement.

Description

technical field [0001] The invention relates to the technical field of offshore oil engineering tests, in particular to a method and device for measuring the law of movement of oil spilled on the water surface in a laboratory. Background technique [0002] With the development of offshore oil and gas fields and the development of industrial technology, submarine pipelines have played an irreplaceable role in the production and transportation of crude oil. During the whole process of submarine pipeline operation, pipeline leakage, perforation and fracture will lead to oil leakage. After the leakage accident, the oil spilled will drift to the coastline with the wind and waves, which not only causes serious environmental pollution to the sea surface, but also affects the environmental quality and biological diversity index of coastal waters due to the potential toxicity and bioaccumulation effect of petroleum hydrocarbon pollutants. The serious decline will cause serious damag...
