摘要
岩石力学参数是表征裂缝发育特征及指导压裂的关键参数，其求取方法主要有岩心实验测定和声成像测井两种，但获取成本较高、数据相对稀少。常规测井资料和三维地震资料在各油气田开发区已被广泛录取，利用多元回归技术建立常规测井资料与岩石力学参数之间的关系，经过误差校正可以准确计算井眼岩石力学参数；再根据测井资料纵向分辨率高和三维地震资料横向分辨率高的特点，利用地球物理反演和三维建模技术建立研究区内岩石力学参数三维模型，可以预测井间岩石力学参数。
Rock mechanic parameters are the key parameters of characterizing fracture development properties and guiding the fracturing, which can be got through the core test and sonic imaging logging, but the obtained costs are rather higher and the data are insufficient. Conventional logging and 3D seismic data have been widely collected in each developed blocks of oil ＆ gas fields. With the help of multiple linear regression technique, the relationship between the conventional logging data and rock mechanics parameters is established, the parameters of the borehole can be accurately calculated by error correction; and moreover according to the high vertical resolution of logging data and high horizontal resolution of 3D seismic data, the 3D rock mechanics parameters model of the researched area is established with the help of the geophysical inversion and 3 D modeling technique, and then the parameters among the wells can be predicted.
