Rock Physics Modeling(岩石物理建模)研究综述
Rock Physics Modeling 岩石物理建模 - In step two, a distinct and specialized regression model is selected from more sophisticated methods (empirical models, statistical regression, virtual intelligence, and rock physics modeling) for determining the final shear wave velocity profile. [1] Quantitative interpretation of shale reservoirs should be done properly, including such steps from rock physics modeling, fluid substitutions, and predicting elastic properties to obtain the best image of shale systems and perhaps to lower drilling risks in the future. [2] The effects of shale composition on the joint elastic-electrical properties of shales can be explored using a combination of suitable well data and rock physics modeling. [3] Our main scheme in this study was distinguishing between fracture porosity and matrix porosity in coalbed methane reservoirs through a novel approach which is the joint usage of NMR transverse relaxation (T2) measurements and rock physics modeling based on Levenberg-Marquardt (LM) algorithm. [4] Rock physics modeling is applied in this study as it is an accurate, precise and practical method for the case of carbonate reservoirs. [5] These posterior models are finally linked to velocity models by rock physics modeling. [6] For any type of rock physics modeling or anisotropy analysis, individual elastic moduli of clay minerals, their orientation distribution functions (ODF) and their volume fractions are imperative. [7] Therefore, to understand the seismic and elastic character of Sembar shales, rock physics modeling and seismic attribute analysis have been done. [8]在第二步中,从更复杂的方法(经验模型、统计回归、虚拟智能和岩石物理建模)中选择一个独特且专门的回归模型来确定最终的剪切波速度剖面。 [1] 页岩储层的定量解释应该正确进行,包括岩石物理建模、流体替代和预测弹性特性等步骤,以获得页岩系统的最佳图像,并可能降低未来的钻井风险。 [2] 可以结合合适的井数据和岩石物理模型来探索页岩成分对页岩联合弹性电特性的影响。 [3] 我们在这项研究中的主要方案是通过一种新颖的方法来区分煤层气储层中的裂缝孔隙度和基质孔隙度,该方法是结合使用 NMR 横向弛豫 (T2) 测量和基于 Levenberg-Marquardt (LM) 算法的岩石物理建模。 [4] 本研究采用岩石物理建模,因为它是针对碳酸盐储层情况的准确、精确和实用的方法。 [5] 这些后验模型最终通过岩石物理建模与速度模型联系起来。 [6] 对于任何类型的岩石物理建模或各向异性分析,粘土矿物的单个弹性模量、它们的取向分布函数 (ODF) 和它们的体积分数都是必不可少的。 [7] 因此,为了解森巴页岩的地震和弹性特征,进行了岩石物理建模和地震属性分析。 [8]
