摘要: 选用裂缝体积密度作为构造裂缝定量化参数,对基于钻井岩心的裂缝体积密度的计算方法作了改进。统计分析得出,破裂试件裂缝体积密度与试件破裂应变能密度的关系受试件所受的围压变化及试件物性的控制,钻井岩心构造裂缝体积密度与数值模拟应变能密度的关系同试件研究结果有可比之处。在上述研究基础上,建立了利用钻井岩心裂缝参数和数值模拟应变能密度来定量预测碳酸盐岩储层构造裂缝体积密度的方法,并已应用于油田生产。

Abstract: This paper presents a quantitative analysis method of fissure volume density through strain energy obtained from numerical simulation. The volume density is chosen to be the quantitative analysis parameter, and its calculating method in core is improved. The equations of the relationship between fissure volume density and strain energy in samples are influenced by the confining pressure. On the basis of above results, the relation between the fissure volume density in core and strain energy obtained by numerical simulation are analyzed, by which the quantitative analysis method is set up and has been applied in oilfield production.
