| 摘 要： | 根据大量钻井剖面、地震剖面、岩芯观察、野外出露剖面和岩石分析资料,研究了二连盆地近30个凹陷的下白垩统沉积相,并以勘探程度较高的阿南、吉尔嘎朗图等7个凹陷为重点,恢复了早白垩世的岩相古地理环境,总结了下白垩统的沉积特征、主要沉积体系和油气分布规律,并指出今后的油气勘探方向。

| Abstract: | Based on a lot of drilling sections,seismic sections,core observations,field exposure sections and petrological analysis data,the sedimentary facies of Lower Cretaceous strata of about thirty depressions in Erlian Basin have been studied.The emphasis was puton seven depressions induding Anna and Jiergalangtu with high level of prostecting reconstracting the lithofacies paleogeographic environment of lower Cretaceous and summarizing the sedimentery features,the origin of major sandbodies and the laws of hydrocarbon distribution of Lower Creaceous.In the meantime,this paper pointed out the direction of oil and gas exploration in futre in Erlian Basin. |
