川西坳陷东坡侏罗系沙溪庙组三角洲河道砂体构型
|
摘要
利用钻测井、岩心分析、物探等资料,对川西坳陷东坡地区沙溪庙组三角洲河道砂体的岩相特征、构型分类、构型主控因素以及油气富集规律进行研究。川西坳陷高庙子-中江地区在沙溪庙期整体以三角洲沉积体系为主,文中依据砂体内部岩相结构、类型及组合等关系,提出了砂体构型的4种类型划分方案,即水动力频繁变化复合构型、河道迁移变化复合构型、进退积叠置均一构型、侧积叠置均一构型;而河道侧积体宽度、物源远近、河道弯度、可容纳空间量与沉积物供给量比值的大小均会影响砂体构型的变化。
According to the drilling and well logging, core analysis and geophysical data, the facies characteristics of delta river channel sand body, sand body configuration classification, main control factors, and oil and gas enrichment regularity of Shaximiao Group in West Sichuan Depression east slope area were studied. The Gaomiaozi-Zhongjiang area in the western Sichuan Depression is dominated by the delta depositional system during the Shaximiao period. In this paper, four types of sand body configurations are proposed based on the structure, type and composition of sandstone, the complex configuration of hydrodynamic change, the change of the channel migration, the configuration of stacking, and the configuration of the side product stack. The width of the channel, the distance from the source, the curvature of the river and the size of the space/sediment supply will affect the change of the sand body configuration.
