“三高井”井喷突发事件救援实施方案探讨

Discussion on the Implementation Scheme of Blowout Emergency Rescue in "Three High Wells"

"三高井"(高压、高产、高含硫)由于所处地层压力较大,一旦发生井喷事故常常伴随着剧烈且无控制的火焰敞喷之势,井口装置、顶驱、泥浆泵、各类管汇及各类监测、检测设备很快就会被损毁并形成堆积,对抢险救援的开展形成极大的障碍,同时伴随着大量的油气资源喷出,既损失了能源资源,还会形成有毒气体扩散到空气当中,过程会造成严重的人员伤亡和财产损失,因此,需要探索出一整套科学高效、安全可靠的抢险方案,从而提高"三高"油气井井喷突发事故的应急处理能力。

Because the formation pressure of the"Three High Wells"(high pressure,high yield and high sulfur content)is relatively high,once a blowout accident occurs,it is often accompanied by a violent and uncontrolled flame blowout,and wellhead devices,top drive,mud pumps,various manifolds and various monitoring and testing equipment will soon be damaged and piled up,which will form a great obstacle to the development of emergency rescue.At the same time,a large amount of oil and gas resources will be ejected,which will not only lose energy resources,Toxic gases will also diffuse into the air,which will cause serious casualties and property losses.Therefore,it is necessary to explore a set of scientific,efficient,safe and reliable emergency rescue plans,so as to improve the emergency handling ability of blowout accidents in"Three High"oil and gas wells.
