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。
Using the crack volume density as the quantitative parameter of structural fractures, the calculation method of the crack bulk density based on the drilling core is improved. The statistical analysis shows that the relationship between the fracture bulk density and the ruptured strain energy density of the specimen is influenced by the confining pressure and the control of the physical properties of the specimen. The relationship between the bulk density of the drilling core and the numerical simulation of the strain energy density The results of the test with the specimen comparable. Based on the above studies, a method of quantitatively predicting the bulk density of structural fractures in carbonate reservoirs by using drilling core fracture parameters and numerical simulation of strain energy density has been established and applied to oilfield production.
