| 中文摘要: |
| 恩平凹陷新近系韩江组地层为海相三角洲沉积，砂体大面积发育，油气资源丰富。其南部D区块油气资源以钻井平台丛式井开发为主，井网不均匀，井资料少，沉积微相边界刻画难度大，需要在沉积环境特征分析的基础上确定沉积亚相类型，为后油气资源开采提供地质依据。本次研究充分利用岩芯、测井资料，分析了岩芯的矿物特征、结构特征、构造特征、生物特征，同时结合测井特征和砂体垂向韵律，得出研究区韩江组地层为辫状河三角洲前缘亚相，上述研究成果为后续重点层沉积微相精细刻画奠定基础。 |
| 英文摘要: |
| The strata of the Neogene Hanjiang formation are marine delta , in Enping depression，with a large area of sand and rich of oil. The oil in Block D are mainly developed by cluster wells.There are few well data in block D,and the well pattern is uneven.so,it is di.cult to depict sedimentary microfacies . It is necessary to determine the type of sedimentary subfacies based on the analysis of sedimentary environment characteristics, so as to provide Geological knowledge for subsequent oil resources exploitation.This study makes full use of the core and logging data, and de.nes the sedimentary environment of Hanjiang formation as braided river delta front subfacies from the aspects of mineral characteristics in core, architectural features, structural features, biological characteristics, bore log characteristics and sand body characteristics. The research results lay a solid foundation for accurately descripting the sedimentary microfacies of the key layers. |
