Anisotropic Rock Physics Templates (RPTs) are efficient tools to interpret well logs. In this work, micromechanical modeling is used to calculate the effective properties of heterogeneous and anisotropic rocks due to the presence of fluid-filled aligned fractures or other minerals, e.g. clay, quartz and calcite. When the spheroidal inclusions are aligned, the transversely isotropic symmetry is described by Hill’s 5 elastic moduli, which are obtained after solving a system of nonlinear algebraic equations. New anisotropic Rock Physics Templates are based on these elastic moduli, in which it is easy to identify the presence of fluids in a reservoir. It has been observed that effective properties depend strongly on the aspect ratio of inclusions, pore fluid, and mineralogy. These new numerical results are similar to with others already published when the aspect ratio is set to 1. For aspect ratios $\delta$ of $0.25,0.5,$ and 0.75, these ternary plots give new elements of interpretation and analysis of results obtained either in a rock physics laboratory or in the field station. For instance, lower aspect ratios $\delta =0.5$ until values nearly to $\delta =1$ consider thick interbedded formations or fluid-filled pore under compaction. The latter will lead to a better characterization of the heterogeneous and anisotropic reservoir rocks, which are linked to producing commercial hydrocarbon areas. Herein, a shale gas reservoir is consistently identified by the proposed anisotropic RPTs.

各向异性岩石物理模板 (RPT) 是解释测井记录的有效工具。在这项工作中，由于存在充满流体的对齐裂缝或其他矿物，例如粘土、石英和方解石，微观力学模型用于计算非均质和各向异性岩石的有效特性。当球状包裹体对齐时，横向各向同性对称性由希尔 5 弹性模量描述，这是在求解非线性代数方程组后获得的。新的各向异性岩石物理模板基于这些弹性模量，可以很容易地识别储层中流体的存在。据观察，有效性质很大程度上取决于包裹体的纵横比、孔隙流体和矿物学。$\delta$ 的 $0.25,0.5,$和 0.75，这些三元图提供了解释和分析岩石物理实验室或现场站获得的结果的新元素。例如，较低的纵横比$\delta =0.5$ 直到值接近 $\delta =1$考虑压实下的厚互层或充满流体的孔隙。后者将导致对与生产商业油气区相关的非均质和各向异性储集岩进行更好的表征。在本文中，通过提出的各向异性 RPT 一致地识别了页岩气储层。
