Ocean platform oil-gas leakage explosion coupling experiment platform

Abstract

The invention relates to an ocean platform oil-gas leakage explosion coupling experiment platform, which comprises an oil and gas leakage diffusion system, a wind generation system, a wave generationsystem, a deepwater semi-submersible platform simulation system and a data acquisition and control system; oil gas leakage diffusion occurs in the oil gas leakage diffusion system; the oil gas is distributed around the deepwater semi-submersible platform; a sea wind environment is simulated through the wind generation system; a sea wave environment is simulated through the wind generation system;diffusion data of oil gas on the platform are collected through a concentration measuring instrument and an oil gas sampling probe on a monitoring point; the control terminal can control the detonating device at the wellhead to carry out an oil gas burning explosion experiment; overpressure data and flame development images of oil gas burning explosion are obtained through the pressure sensors, the thermocouples, the concentration measuring instruments and the high-speed cameras on the monitoring points, and collected diffusion data and burning explosion data are processed through the information processor and displayed on the control terminal. The experiment platform considers the influence of platform congestion, sea wind and sea waves, and accords with engineering application. Meanwhile, the experiment platform is high in safety coefficient and easy to operate, and the experiment platform is provided for risk assessment of oil and gas leakage diffusion of the deepwater semi-submersible platform.

Description

technical field [0001] The invention relates to an offshore platform oil and gas leakage explosion coupling experiment platform, which belongs to the technical field of oil and gas safety. Background technique [0002] With the deepening of offshore oil and gas exploration and development, the problem of blowout on drilling platforms has become increasingly prominent. Offshore drilling procedures are complex, well control is difficult, and well kicks or blowouts occur from time to time. Well kicks or blowouts cause a large amount of oil and gas to be ejected from the wellhead and mix with air, forming a large-scale flammable gas cloud around the platform, which will burn when encountering an ignition source, and then cause a catastrophic explosion accident. In 2010, a severe blowout occurred during the operation of the "Deepwater Horizon" drilling platform, which caused a violent explosion, killing 11 people, injuring 17 people, sinking the platform, and leaking a large amo...

In 2010, a severe blowout occurred during the operation of the "Deepwater Horizon" drilling platform, which caused a violent explosion, killing 11 people, injuring 17 people, sinking the platform, and leaking a large amount of crude oil

However, when studying oil and gas diffusion, the sea breeze seriously affects the diffusion of oil and gas on the platform, and the diffusion of oil and gas is also affected by the congestion obstacles on the platform, and the congestion obstacles have an aggravating effect on the explosion accident of the platform, while the empirical model And CFD simulation does not carry out fine modeling of the object model in the environment, resulting in low accuracy of the model
