Abstract: The microanisotropy characteristics of the oil and gas reservoirs are one of the important contents in reservoir geology. Based on the authentic sandstone micromodel experiment, the microanisotropy characteristic of Chang 3 reservoirs of Zhenbei area in Ordos Basin was analyzed. Chang 3 reservoirs belong to tight sandstone. The authentic sandstone micromodel experiment audiovisually display the intense microanisotropy of Chang 3 reservoirs in this area. The sandstone pore structure and diagenesis are main factors influencing Chang 3 reservoirs microanisotropy. The dissolution resulted in the intense microanistropy of Chang 3 low permeable sandstone, but this sandstone formed high permeable zone of Chang 3 reservoirs in this area.
