陇川盆地中新统地震相分析与油气勘探
|
摘要
在分析滇西陵川盆地地质特征的基础上，对盆地的地震层序、地震相进行了综合研究，并结合钻井岩心相及测井相的分析，进行了盆地沉积相解释推断，解释出湖相、扇三角洲、近岸水下扇、塌积扇等不同的沉积相类型以及它们的展布特征和古沉积环境，认为沉积中心和沉降中心不一致，盆地东北部凹陷的岩性可能相对较细。并且指出了相对有利的可能生油凹陷及油气勘探远景区。
Based on the analysis of the geological features of Longchuan basin, the paper studies theseismic sequence and seismic factes of Miocene in the basin,explains the sedimentary factes(such as lacustrine factes, fan delta, f&ns, etc.)together with the study of drillins core fscies and welluloggingfactes,and analyzes the distribution and paleoenvironment of these factes. The paper suggcsts that thedepocenter iS not the same to the depression center and that the elastic rock in the northeast depressionis relatively fine. At last, the paper pointS out the favorable prospect areas.
