摘要
通过储层流体包裹体的研究,结合源岩生排气史、断裂活动史,分析了三肇地区登娄库组天然气充注期次及成藏过程。研究表明,该地区登娄库组天然气充注过程主要有两期,分别是泉头组沉积末期和嫩江组沉积末期,其中泉头组沉积末期是主要成藏期,嫩江组沉积末期是次要成藏期。
To confirm the migration periods and accumulation process of natural gas is very important for studying the formation and distribution laws of gas pools. The diagenetic fluid inclusion of reservoirs can reflect the physical and chemical conditions when fluid is trapped and provide important information about hydrocarbon inflow. By studying on fluid inclusion combined with the generation and expulsion history of source rocks and history of fault,the inflow periods and accumulation process of gas in Denglouku Formation of Sanzhao region are analyzed in this paper. Research reveals that there are mainly two periods of gas inflow process in the field,which are the later period of Quantou Formation and the later period of Nenjiang Formation. In which, the later of Quantou Formation is the key accumulation period, the latter of Nenjiang formation is the less important accumulation period. The actual gas exploration of the area proves that the above method analysis is correct.
