摘要
根据湖泊陆相高分辨率层序地层学理论 ,综合利用岩心、测井和地震资料 ,对渤南洼陷沙三段层序地层和层序内体系域类型进行了识别和划分 ,并对层序地层的特征和演化进行了分析。研究结果表明 ,渤南洼陷沙三段储集层主要位于层序Ⅰ的中上部 ,并划分出 1个三级层序 ,3个准层序组 ,13个准层序。体系域类型包括湖侵体系域、高水位体系域和湖泊萎缩体系域。渤南洼陷下第三系沙三段浊积扇扇中辫状沟道和沉积叶状体是今后油气勘探的新领域。
By using the theories and ways of sequence stratigraphy of lacustrine facies, as well as data of cores, loggings and seismic, the sequence strata and systems tract in sequence in Bonan depression is divided into one three scale sequence, three parasequence sets and thirteen parasequences. By analysing the characteristics of sequence strata and its evolution, the scientific foundation for next exploration is offered. The reservoir of Es 3 section is mainly situated on the middle upper part of sequence Ⅰ. The system tract includes three types of lacustrine transgression system tract(LTST), highstand system tract(HST) and lacustrine contraction system tract(LCST). Brained channels in central fan and lobes are thought as the next exploration areas.
