摘要
通过储集层流体包裹体的研究,结合烃源岩生排气史、断裂活动史,分析了大庆长垣以东地区登娄库组天然气充注期次及成藏过程。认为该区登娄库组储集层内至少发生过两期天然气充注:早期为泉头组沉积末期,是主要成藏期;晚期为嫩江组沉积末期,是次要成藏期。该区天然气勘探实践已证明了上述分析方法和结论的正确性。
The analyses of fluid inclusions in the reservoirs composed by the Denglouku Formation in east Daqing placanticline, and gas and oil generation from source rocks and the history of fracturing reflect the filling history and process of the gas. Two major gas filling process had happened in the Denglouku Formation, as the later period of Quantou Formation and the later period of Nenjiang Formation, in which the later Quantou Formation is the key accumulation period and the later Nenjiang Formation is the secondary rank accumulation period. The exploration in this area practically proved the inferring and analysis.
