摘要:
为了评价井喷事故时喷射火的风险，对比分析Flacs、Thornton模型和点源模型在不同泄漏速率、风速下喷射火热辐射强度计算结果，探讨在相同泄漏速率或相同风速下各模型之间的差异。根据塔里木某口油井的工况，分析在风速为7 m/s，泄漏速率分别为200，170，140，120，90 kg/s和在泄漏速率为140 kg/s时风速为12，7，3 m/s工况下热辐射强度随距离的变化，讨论热辐射强度的空间分布和安全距离的动态变化过程，分析在相同工况相同距离处3种模型的热辐射强度差异及原因。研究结果表明：一般情况下，点源模型、Flacs和Thornton模型在相同位置处所计算的热辐射强度依次增大。由于Thornton模型中未包含修正系数，故通过对比分析结果为Thornton模型添加修正系数以应用于实际。
Abstract:
In order to evaluate the risk of jet fire in the well blowout accidents,the calculation results of the thermal radiation intensity of jet fire under different leakage rates and wind speeds by the Flacs,Thornton model and point source model were compared and analyzed,and the difference between the models under the same leakage rate or wind speed was discussed.According to the working conditions of an oil well in Tarim,the variation of thermal radiation with distance under the conditions of the leakage rate of 200 kg/s,170 kg/s,140 kg/s,120 kg/s,90 kg/s respectively with the wind speed of 7 m/s,and the wind speed of 12 m/s,7 m/s and 3 m/s respectively with leakage rate of 140 kg/s was analyzed.The spatial distribution of thermal radiation intensity and the dynamic change process of safe distance were discussed,and the difference and reasons of thermal radiation intensity by three models at the same distance under the same working conditions were analyzed.The results showed that in general,the thermal radiation calculated by Flacs,point source model and Thornton model at the same location increased in turn.Because the Thornton model did not contain the correction coefficient,through the comparative analysis results,the correction coefficient was added to the Thornton model to apply in practice.
