| 摘要: |
| 本文在建立取芯井段岩-电转换关系及测井相-沉积相解释模型的基础上,对沙二段1—3砂组进行了详细的沉积相分析。确定其主要为辫状河三角洲沉积体系的水上平原沉积,次为三角洲前缘沉积;识别出三角洲平原、三角洲前缘和前三角洲3个亚相及分流河道河床、心滩、边滩等11个微相类型;并对各微相类型的沉积特征和剖面结构进行了讨论。 |

| Abstract: |
| Sedimentary facies analysis is dealt with in detail for the 1st-3rd sandstone beds in the second member of the Shahejie Formation on the basis of the relationship between the well logging facies and sedimentary facies. The 1st-3rd sandstone beds are interpreted as delta plain deposits and delta front deposits in the braided delta depositional system,which may be further divided into three subfacies including the delta plain,delta front and prodelta subfacies,and eleven microfacies including the channel sill,channel bar,point bar microfacies and so on. |
