摘要

为评价页岩油气开发中的泥页岩可压裂性,先由计算得出泊松比、杨氏模量两个岩石力学指标,再由弹性参数法算出脆性特征参数。同时分析了该段脆性矿物组成特征。苏北盆地高邮凹陷阜四段综合评价显示,E_1f_4~E可压裂性最好,E_1f_4~C和E_1f_4~A次之,E_1f_4~F最差。页岩脆性指数越高,裂缝越发育。
        To evaluate the compressive cracking of shale oil and gas development, in this paper, two rock mechanical indexes of Poisson's ratio and Young's modulus are calculated. The brittle characteristic parameters are calculated by the elastic parameter method. At the same time, the composition characteristics of brittle minerals are analyzed. The comprehensive evaluation of the four sections of Gaoyou Depression in the northern Jiangsu Basin showed that E_1f_4~E had the best fractility, followed by E_1f_4~C and E_1f_4~A, and E_1f_4~F was the worst. The higher the shale brittleness index, the more cracks develop.
