摘　　要：西峰油田主力含油层是三叠系延长组长8和长6两个油组,近年来在勘探开发过程中频繁出现CO等有害气体中毒事故,对油田安全生产构成严重的威胁。通过对沉积背景、物源、有机质演化程度、盆地环境演化、矿物成分、煤层及伴生气成分检测等地质特征详细的研究,认为西峰油田有害气体的来源与储集层本身没有直接关系,而是由高能气体压裂工艺措施所造成。Chang 8 and Chang 6 members of Yanchang Formation were the main oil formations of Triassic reservoirs in Xifeng Oilfield.With many serious CO poisoning events happened in the process of oil exploration and development in recent years,the safety of oilfield production was seriously threatened.Based on the comprehensive analyses of the geologic characteristics,such as depositional background,provenance,organic matter,basin evolutional stages,mineral component,coalbed and associated gas detecting,it indicates that the reasons to produce the poisoning CO gas is HEGF and isn't related with reservoir itself.
