There are a large number of natural fractures in Triassic reservoir in Jiyuan area of Ordos Basin. Based on core, microscopic thin slice and logging interpretation, the palaeomagnetism, ground stress and homogenization temperature are applied to analyze the characteristics and forming stages of the natural fractures of Chang 4+5 reservoir in southern Puziwan area, and the influencing factors for fracture distribution are studied. The result shows that the natural fractures of Chang 4+5 reservoir developed well in the study area, and they are mainly of high-angle and effective fractures. The direction of fractures is affected by regional tectonic movement, and mainly of NE-SW. Lithology, strata thickness and sedimentarymicrofacies are the main influencing factors for fracture development.
