Device and method for simulating abyssal region underwater oil spillage

Abstract

The invention belongs to the petroleum engineering field, and particularly relates to a device and a method for simulating abyssal region underwater oil spillage. The device for simulating the abyssal region underwater oil spillage comprises a pressure control system, a mixing injection system, an experimental model system and a water supply and drainage system, wherein the pressure control system supplies pressure for the experimental model system and the mixing injection system, the mixing injection system injects a mixture formed by mixing methane gas and crude oil according to a certain proportion into the experimental model system, the experimental model system supplies a high pressure and low temperature abyssal environment for an experiment, and the water supply and drainage system supplies a low temperature water source for the experiment and discharges sewage after the experiment is finished. The device and the method for simulating the abyssal region underwater oil spillage can simulate the abyssal oil spillage experiments under different pressure, different temperature and different jet velocity conditions and the like, provide accurate model parameters and effective data for an abyssal oil spillage model, and can confirm accuracy of the abyssal oil spillage model and simulate oil gas behavior fate under the abyssal environment. The device for simulating the abyssal region underwater oil spillage is simple to operate, and the method for simulating the abyssal region underwater oil spillage is easy to implement and high in feasibility. A measurement method used in the method for simulating the abyssal region underwater oil spillage is scientific, and can achieve high accuracy parameter measurement.

Description

Technical field [0001] The invention belongs to the field of petroleum engineering, and specifically relates to a device and method for simulating underwater oil spills in deep water areas. Background technique [0002] With the increasing scarcity of land oil resources and the continuous increase in global oil and gas demand, people are exploring and developing more and more offshore oil and gas resources, especially deepwater oil and gas resources. Underwater mining, especially under deep water conditions, and pipeline transportation of oil and gas resources has become possible. However, there are many important problems and environmental hazards in the process of deep water oil and gas mining. Among them, the most obvious and most serious one is underwater in deep water. Oil spill accident. The transport process of pollutants from underwater oil spill accidents in deep water areas in the marine environment usually includes buoyant diffusion in the near area (underwater) and t...

AI Technical Summary

Problems solved by technology

[0003] However, for a long time, due to the limitation of the deep water environment and other conditions, there are not many studies on the floating and diffusion of oil spills in the underwater environment, especially in the deep water environment, and the research on the behavior of oil and gas in the deep water environment is not deep enough. There is no experimental device capable of simulating underwater oil spills in deep water

These have caused great difficulties for us to fully understand the deep water oil spill and how to deal with the oil spill
