Abstract: This paper studied the distribution of the fracture in low-permeability sandstone reservoir in Zhangpenggou area, eastern Junggar basin, and considered that fracture spacing generally has a log-normal distribution, and increases with the formation thickness.There is better linear relationship among the fracture spacing, propagation and height.The fracture was controlled by li thologic facies and structural stress.
