Seabed oil spill prediction method

Abstract

The invention discloses a seabed oil spill prediction method, relates to the field of marine environmental science, and is used for solving the problem that seabed oil spill cannot be grasped and controlled due to less research on a seabed oil spill model. The method includes: in an initial stage of seabed oil spill, the displacement of oil droplets in seabed oil spill under the entrainment effect, the buoyancy effect and the dragging effect is determined by employing a Lagrange integration formula and a concentration gradient formula, the oil droplets start to float from a seabed oil spill region under the entrainment effect, the buoyancy effect and the dragging effect, and when the oil droplets rise in the seabed, the rising speed of the oil droplets is determined through a first formula according to the buoyancy to the oil droplets; and when the oil droplets rise to the sea surface from the seabed, the drifting trajectory of the oil droplets in a certain depth is determined through a second formula and the diffusion distances of the oil droplets in the certain depth and on the sea surface are determined through a third formula under the effects of a sea three-dimensional flow field and a sea surface wind field.

Description

technical field [0001] The invention relates to the field of marine environment science, and more specifically relates to a seabed oil spill prediction method. Background technique [0002] With the sharp increase in the demand for oil resources in the development of the global economy, the offshore oil development industry is booming. my country has a vast sea area and rich oil and gas resources. However, in the process of developing and utilizing marine resources, the development of offshore oil and gas fields and the development of industrial technology will inevitably bring corresponding engineering hidden dangers, such as stratum fractures caused by improper operations, and leakage of wellheads and pipelines. , Ship oil spills, etc. As offshore oil and gas field operations enter the era of deep water and ultra-deep water, their engineering equipment is gradually developing into a large-scale, intensive, complex, and automated underwater production system. Due to the co...
