松辽盆地西南部青山口组三段底界不整合面与油气分布
|
摘要
青山口组三段(K2qn3)底界不整合面对松辽盆地西南部的油气分布产生重要影响。通过精细地层对比、高频地层单元的横向变化特征分析、岩性岩相特征分析、电性变化特征和地震反射波组研究,笔者等发现青三段底界是一个较大规模的区域性不整合面。首次提出该不整合面对松辽盆地南部西区的油气分布产生重要影响,主要表现在以下几个方面:①不整合面是油气长距离运移的有利通道,预测在套堡外围古潜山侧缘和西斜坡古湖湾发育区形成地层和岩性油气藏;②在坡折带,不整合面之上所形成的低水位期下切谷、斜坡扇、低位扇和水侵时期的超覆体,是形成多类型隐蔽性油气藏的有利空间;③在前缘相带,不整合面可以改善薄互层储集条件,增强油气储集性能。
Although unconformity at the bottom of the Cretaceous Qingshankou Formation affected the distribution of oil and gas, identifying and classifying the boundary are difficult and are neglected. This paper carried out research of fine stratigraphic correlation, high-resolution stratigraphy, changes of linthology and electronic property, characteristics of seismic reflection. Writers point out that bottom of the formation is a macro-scale regional unconformity and the unconformity severely affected the distribution oil/gas and styles of reservoir in the southwesters Songliao Basin. The effects include:(1) The unconformity was a fine passage for oil/gas migration, which would caused the formation of stratigrapgical overlap reservoir in the lateral Taobao buried hill and caused the formation of lithological reservoir in lacustrine bay region in the western slope of the Songliao Basin; (2) The incised valley, slope fan, fan of LST, and overlap-body of transgression system tract provided excellent geological condition for the formation of subtle reservoir of multiple styles in the slope break region; and (3) The unconformity could improve reserves conditions for the accumulation of oil/gas, and could enlarge the distribution of oil and gas.
