为了要研究砂泥岩互层裂缝发育与地层厚度的效应,分析裂缝发育的机制,并利用数值模拟的方法对沙泥岩互层的厚度进行计算,分析不同厚度砂泥岩互层裂缝发育地层厚度的密度、开度、和孔隙度,从而分析砂泥岩互层裂缝发育的模式。根据计算结果显示,砂泥岩互层的厚度越薄,其裂缝的产生更加容易,砂泥岩互层裂缝的发育地层厚度也受其影响,本文就砂泥岩互层裂缝发育地层厚度效应进行分析,从中探讨其之间的关系。
In order to study the effect of interbedded fracture development and formation thickness of sandstone and mudstone, the mechanism of fracture development is analyzed. The thickness of interbedded sandstone and mudstone is calculated by numerical simulation. The density of formation thickness of interbedded fracture of sandstone and mudstone is analyzed. , Opening degree and porosity, so as to analyze the pattern of sandstone and mudstone interbed fracture development. According to the calculation results, it is found that the thinner the interbedded sand and mudstone is, the easier it is to produce cracks and the thicker the strata of interbedded fractures of sandstone and mudstone are. The thickness effect of interbedded fractures of sandstone and mudstone is analyzed in this paper, Explore the relationship between them.
