| 摘 要： | 对济阳坳陷中生代沉积特征的综合研究, 初步提出一套改造型残留盆地沉积相研究方法, 强调从野外露头、岩芯、岩屑录井、测井、人工地震和盆地结构6个方面进行沉积相综合研究, 并与研究区周围地层沉积特征、岩芯沉积相识别、沉积相垂向演化、测井相、地震相和沉积体系分布研究相结合。其中最核心的技术是平衡剖面及地震约束下的连井剖面沉积相纵横向研究。研究认为济阳坳陷在中生代由多个时而分割时而相连的湖盆组成, 主要发育冲积扇相、河流相、扇三角洲相、三角洲相、湖泊相及沼泽相。

| Abstract: | Through an integrated study of Mesozoic sedimentary characteristics in J iyang depression, the authors put forward a set of methods for studying sedimentary facies in reworked residual basins. The main concept including the field outcrop, core, sample log, well logging and the basinal structures. Integration research has been done includes sedimentary characteristics of strata, sedimentary facies recognition of core, vertical variation of sedimentary facies, logging facies, seismic facies and sedimentary system distribution. The most important methods are the balanced cross-section and sedimentary analysis of well-to-well correlation sections in seismic restraint. The study app roves that J iyang dep ression was composed of the lake basins divided up or connect by catches in Mesozoic, and developed the alluvial fan facies, fluvial facies, fan delta facies, delta facies, lacustrine facies and swamp facies. |
