摘要
深水条件下井控失效存在引发油气泄漏的风险,为了解泄漏后果及制定救援措施,需对深水钻井井喷水下的油气泄漏扩散进行模拟。采用Fluent软件模拟水下3000 m处油气泄漏扩散过程,考虑了海水压力、温度和洋流流速等深水环境。结果表明:高泄漏流量下的天然气在海面的扩散能力显著增强;高泄漏流量下原油在上升过程中形成的油团规模更大,受洋流水平拖拽作用更明显。研究结果为深海油气泄漏应急响应与井控策略制定提供了理论支撑。
Under deepwater conditions,the failure of well control can lead to the risk of oil and gas leakage.To understand the consequences of leakage and formulate rescue measures,it is necessary to simulate the underwater oil and gas leakage and diffusion during deepwater drilling blowouts.The Fluent software was used to simulate the oil and gas leakage and diffusion process at a depth of 3000 m underwater,taking into account the deepwater environment such as seawater pressure,temperature and ocean current velocity.The results show that the diffusion ability of natural gas on the sea surface is significantly enhanced under high leakage flow;Under high leakage flow,the scale of oil clusters formed during the ascent of crude oil is larger and the horizontal dragging effect of ocean currents is more obvious.The research results provide theoretical support for emergency response and well control strategy formulation for deepwater oil and gas leakage.
