    • Abstract
  • The Chang-2 pay sets of the Youfangzhuang Oil Field in the Ordos Basin consist of the sedimentary microfacies such as distributary channel, natural levee, crevasse fan and marsh microfacies. Major reservoir sandstone bodies include distributary channel and natural levee sandstone bodies. Good connectivity and physical property and poor inhomogeneity are identified along the parallel direction of sediment supply, and vice versa along the vertical direction of sediment supply. The normal rhythmicity of the sandstone bodies along the vertical direction may be harmful to the formation of water-drived oil. The numbers of sandstone beds are positively correlated with the inhomogeneity of the Chang-2 pay sets of the Youfangzhuang Oil Field.
