摘要： 以准噶尔盆地东部帐篷沟地区为例, 研究了低渗透砂岩储集层中裂缝的分布规律。低渗透砂岩储集层中裂缝的间距常呈对数正态分布,并与岩层厚度密切相关,随着岩层厚度增加,裂缝间距增大。裂缝的间距、延伸长度及高度等参数之间具有较好的线性关系。低渗透砂岩储集层中裂缝的发育程度受岩相和构造应力双重因素的控制。

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.
