Abstract

Abstract: In practice,the initiative igniting the blowout jet flow is an efficient method to confine the harmful range and production risk.The blowout jet flows of natural gas with CO₂ and H₂S were theoretically analyzed.A geometry model close to the production conditions was constructed.The well blowouts with different concentration of sour gas at different well pressure and wind velocity were simulated by using the reasonable CFD method.The efficient ignition ranges were determined under different flow velocity and concentration fields.

Key words: sour gas field, well blowout, ignition, jet velocity field, concentration field, numerical simulation

摘要： 在井喷酸性天然气形成射流的可燃空间范围内进行主动点火是控制酸性气田井喷事故危害范围与危害程度的有效方法。对含CO₂、H₂S的天然气井喷情况进行了理论分析,建立了与实际情况接近的几何模型,采用CFD模拟的方法,对不同压力、不同风速、不同酸性气体含量的井喷情况进行了模拟研究,获得了射流速度场、浓度场,得到了不同情况下的有效点火空间范围。
