摘要
通过对辽东凹陷东部斜坡带进行石油地质学分析,发现在其南端周缘发育多套生油层系,储层储集性能较好,形成下生上储型组合,具备了形成大中型油气藏的条件。该区周围存在多个生油凹陷,区域上发育古近系、新近系和前第三系3套储盖组合,基底活动形成的断裂及区域性不整合面形成了油气运移的良好通道。综合认为该区存在较好的油气勘探前景。
The results of petroleum geology analysis conducted in the east slope belt of Liaodong Sag indicate that several series of source rocks and reservoirs with good properties occur in the south of east slope belt. Combinations of lower source and upper reservoir rocks are developed in this area, providing the conditions of forming large or medium scale oil pools. Many petroleum-generating sags occur around the east slope belt of Liaodong Sag and, combinations of reservoir and cap rocks are well developed regionally, such as in Neogene, Eogene and Pre-Tertiary. Faults produced by basement movements and regional unconformities are serviced as effective passages for oil migration. Composite analysis suggests that good potential for exploration exists in this area.
