松南构造认识及无机成因CO_2分布规律研究
摘要
通过广泛运用深重力、地震反射等资料,深化了松辽盆地关于壳幔结构及其控盆作用的认识,全面解剖深大断裂及其特征,揭示基底构造与中、浅层构造成因的内在联系。进而分析了无机成因CO2的分布规律。研究表明,形成于壳幔拆沉作用的深大断裂在盆地后期演化进程中控制了中浅层构造的形成与发展;长岭断陷在断陷期形成的大规模火山,为盆地晚期幔源气提供了储存空间。无机气具有晚期成藏特征,长岭地区与乾安-前神字井控陷断裂临近的大型火山岩体及中、浅层反转构造是无机成因CO2聚集的主要区域。上述规律的发现与总结,对于完善本区下步油气勘探认识具有现实意义。
Data of deep layer gravity and seismic reflection were used to deepen the recognition of crust-mantle structure and basin controlled effect to analyze integrally the big fractures and their characters and reveal internal relation between the base structure and the genesis of mid-shallow structure,and the distribution rules of inorganic-origin of CO2 was consequently analyzed.Study shows that the formation and development of the mid-shallow structure is controlled by the big fractures deposited in crust-mantle reaction at the late stage of basin evolution.The massive volcano formed at the faulting stage of Changling Fault Depression provides a storage space for mantle source gas at the late stage of basin growth.The inorganic gas has the characteristics of late hydrocarbon accumulation.And the inorganic-origin carbon dioxide is mainly distributed at the large-scale of volcane adjoining to Changling and Qian'an-Qianshenzijing deep-seated faults and in the middle-shallow layer inversion structure.The rules are the main areas of inorganic-origin CO2 accumulation.The summary above is of great significance to improve next exploration in southern Songliao Basin.
