摘要

根据地质、钻井、地震等资料综合分析,将下第三系划分为1个巨层序、6个超层序、12个三级层序。在建立了层序地层格架的基础上,结合盆地内沉积层序充填特征及沉积体系的平面分布规律,归纳出不同类型的沉积层序和体系域模式,包括在盆地稳定拉张期梁家地区发育三阶坡折型、万昌地区发育调制盆地型、波太地区发育深水盆地型沉积层序模式。低水位期发育的各类扇体,包括低水位扇、低水位楔、辫状水道以及下切河谷充填砂,都可能构成有效储层,并能形成隐蔽圈闭或复合圈闭。由此预测出12个有利区带。
According to integrated analysis of geology,drilling and seismic data etc.,the lower Tertiary may be divided into one megasequence, six ultrasequences,and twelve tertiary sequences.Based on sequence stratigraphic framework,combing with packing characteristics of sedimentary sequence and areal distribution rule of system tract in the basin,different types of sedimentary sequence and system tract models are generalized,including third break type developed in Liangjia region at the stable tensional stage,regulating basin developed in Wanchuang region,and sedimentary sequence model of deep water basin developed in Botai region.Various types of quadrants developed at lower water level,including low water fans,low water wedge,braided channel and lower cutting valley backing sand,will become favorable oil beds,and form subtle trap or compound traps.Twelve favorable regional belts are predicted in this paper.
