【摘要】：应用流体动力学理论,通过数值模拟得到了浮式钻井生产储卸油装置(FDPSO)泄露速度、泄露位置、环境风速等因素对气体扩散分布的影响。结果表明,定风速下,气体扩散速度水平方向较垂直方向大,平面内横向较纵向大;不同泄露位置下,气体的扩散分布则主要取决于FDPSO的设备布置情况;不同泄露速度或风速下,气体浓度有着先升高后稳定的变化趋势。同时依据模拟分析结果进行了FDPSO油气处理模块安全逃生路线设计。
[Abstract]:Based on the theory of fluid dynamics, the effects of leakage velocity, leakage location and environmental wind speed on the distribution of gas diffusion were obtained by numerical simulation of floating drilling production oil storage and unloading device (FDPSO). The results show that the horizontal direction of the gas diffusion velocity is larger than the vertical direction and the horizontal direction is larger than the vertical direction under the constant wind speed, and the distribution of the gas diffusion at different leakage locations is mainly determined by the equipment arrangement of the FDPSO. Under different leakage velocity or wind speed, the gas concentration increases first and then changes steadily. At the same time, according to the result of simulation analysis, the safe escape route of FDPSO oil and gas processing module is designed.
