【摘要】 针对低渗透油气田在高能气体压裂增产措施中CO气体中毒事件,对CO气体生成进行了深入的研究.研究表明HEGF配方本身是产生CO的直接因素.同时,运用物理模拟和数学模拟方法建立了CO大气扩散模型,并考察了井深、气油比、气体泄放速率、大气稳定度等主要因素对CO气体扩散的影响.该研究为建立监控系统提供了基础技术依据,同时对高能气体压裂安全生产具有重要的指导意义.更多还原

【Abstract】 In order to avoid the poisoning events of CO in the high-energy gas fracture of low-permeability oil-gas fields,the generation of CO is deeply studied.It is shown that the formulation of the explosive for HEGF is the direct cause of producing CO.The diffusion model of CO in atmosphere is established using physical and mathematical stimulations,and the effects of well depth,gas to oil ratio,gas exhausting speed and atmosphere stability on the diffusion of CO are discussed.This study can provide technical basis for establishing CO monitoring system.更多还原
