摘要: 在传统的石油工程岩石力学分析中,大都将地层简化为正交各向异性、横观各向同性性质。在深入分析深层岩石力学所涉及的石油工程背景的基础上,利用现场实钻岩心进行了岩石力学性质正交各向异性实验研究。结果表明,沿垂直于井眼轴线平面上,岩石力学性质的各向异性是客观存在的。而且,在某些极端地质环境下,其各向异性的程度还比较强烈,不能简单的将地层考虑为横观各向同性性质。

Abstract: In the traditional rock mechanics analysis, the formation is always simplified to orthotropic and transverse isotropic. On the basis of detailed analyzing petroleum engineering background regarded to rock mechanics, the rock mechanics orthotropic experiment was done with the drilling core. The experimental results show that the anisotropy of the mechanical property in the plane perpendicular to the wellbore axis is existing. So in some extreme geologic environment, the degree of orthotropic is relatively obvious, the formation can not be simplified to transverse isotropic.
