摘　　要：利用包裹体分析技术对松南气田充注期次和成藏期进行初步分析后认为:松南气田存在四期有机烃类气体充注,分别为泉头组沉积时期、青山口组沉积末期、姚家组沉积末期和嫩江组沉积末期,具有多期充注多期成藏的特点;新近系以来受深大断裂的影响,幔源二氧化碳充注,形成混合气藏。Preliminary analysis on gas accumulation and reservoir forming period in Songnan gas field has been conducted using fluid inclusion technique. The study results indicate that there exists four phases of hydrocarbon gas filling, including depositional period of Quantou Formation, final depositional period of Qingshankou Formation, final depositional period of Yaojia Formation and the final depositional period of Nenjiang Formation. This study has revealed that the Songnan gas field is characterized by multi-periods of gas filling and reservoir forming. Due to the effect of the Neogene deep fault, the gas field is also filled by mantle-derived COz, becoming a mixed type of gas reservoir.
