摘要
叠前弹性波阻抗反演是预测构造煤分布的一种有效方法,不少研究者提出了不同的弹性波阻抗公式,对比分析它们的精度及它们区分构造煤的能力是个值得研究的问题。利用构建的不同煤体类型双层构造煤模型,对比分析了5个典型弹性波阻抗公式的精度和它们区分构造煤的能力。结果表明,苑春方改进的弹性波阻抗公式区分构造煤和原生煤的能力最强。
Pre-stack elastic impedance inversion is one of the effective methods for tectonic coal distribution area prediction. Many scholars have given different elastic impedance formulas. The ability to distinguish tectonic coal of those elastic impedance formulas is a worthwhile exploring problem. This paper constructs some tectonic coal two-layer models based on different coal structures,compares and analyzes the accuracy and the ability of five typical elastic impedance formulas to distinguish the tectonic coal. Study result shows that the elastic impedance formula given by Yuanchunfang has the strongest recognition ability of tectonic coal in those five elastic impedance formulas.
