Among the damage forms, the heat radiation from the natural gas fire flame can threat the onsite and surrounding workers as well as the facilities dramatically. With a practical natural gas well exploration project as an example, using a Computational Fluid Dynamics(CFD) software, the flux field is simulated with well pressures of 10, 20 and 30MPa. In this study, 3 different air velocities and 2 well diameters (63.5 and 88.5mm) are considered in the well blowout and eighteen groups of simulation results are obtained. The simulation results, as well as the heat radiation effects on the circumjacent facilities, are analyzed. It is indicated that both the well pressure and diameter have little influence on the blowout gas velocity with other parameters fixed. With the same well pressure and diameter, the greater the air velocity is, the lower and smaller the effective ignition area will be. Under the simulation conditions, the gas ejection velocity is about 400m/s and the surface temperature of the natural gas flame exceeds 1500K. For the facilities, the damage diameter of the project fire is about 40m; meanwhile the injury diameter of the project fire for human beings is about 104m., authors=null, authorsList=null,

articleAbstract=天然气开发过程中，井喷事故后果非常严重，井喷天然气燃烧产生的热辐射会对井场周边人员及设施造成严重伤害。本文以实际工程项目为例，利用计算流体动力学软件CFD，以3种不同压力、外界风速和2种出口直径为边界条件，分别对井喷情况下的流场分布进行了数值模拟计算，并对模拟结果及其对周边设施的影响进行了分析。数值模拟结果表明，其他参数不变的情况下，压力或出口直径的变化不会导致出口流速的变化，井喷后气流的出口速度约为400m/s，而火焰表面温度超过1500K，喷射火对周边建筑物的损伤半径在40m左右，对人员的伤害半径在104m左右。,
