摘要
From the reservoir geological characteristics, rock composition and diagenesis, physical properties, pore types and so on, this paper analyzes the particularity of sandstone reservoirs in the member 6 to the member 4+5 of the upper Triassic Yanchang Formation from the Hujianshan area of Ordos Basin, and discusses the reservoir characteristics and their relationship with oil accumulation. Oil accumulates in the reservoir layers with different physical properties and many aquifers have high porosity and permeability. So reservoir characteristics itself can not afford a decisive role in the petroleum gathering. There must have a good assemblage of higher physical property value reservoir, conduct pathway and oil source can form oil pool.
