摘要
应用地质、测井、地震资料三维数据体,采用空间网格化和热指标反演拟合等技术,恢复地史和热史。模拟出松辽盆地有三个古热流高峰期;建立超压模型,摸拟青-段向下排烃史,定量计算出青一段靠超压向下排液深度达500m左右;引入流体势概念,模拟油气二次运移、聚集史,提出了松辽盆地三肇凹陷扶、杨油层以垂向向下运移为主,侧向运移为辅的二次运移特点。
Using the geology, well logging and 3-D system of seismic data, along with the spatialgridding and thermal alteration index (TAI) inversion matching for restoring the geologicaland thermal histories, three peak stages of the palaeoheat-flow are modelled. The downwardoverpressured expulsion fluid about 500m, in member l of Qingshankou formation, was quan-titatively estimated by establishing an overpressured model, modelling the history of down-ward expulsion hydrocarbons. The introduction of the fluid potential concept is used to simu-late the histories of secondary migration and accumulation so that both the predominantdownward vertical migration and the auxiliary lateral migration, in Fuyu and Yangdachengzioil-bearing formations of Songliao basin's three Zhao (Zhaodong, Zhaoyuau and Zhaozhou) troughs were characterized.
