基于测井资料的矿物横波速度预测

Prediction of mineral shear wave velocity based on logging data

本文通过建立矿物的物理模型进行研究,分析了不同的孔隙度、泥质含量和扁率值对纵横波速度的影响。利用筠连地区地质矿物进行横波预测,最大误差5%,平均误差3.5%左右。根据在筠连地区确定矿物参数,准确预测了自贡工区龙马溪组矿物横波速度。

In this paper,the physical model of mineral is established to study the effect of different porosity,shale content and flatness on the P-wave velocity.The maximum error is 5%,and the average error is about 3.5%.Based on the determination of mineral parameters in Junlian area,the shear wave velocity of Longmaxi formation in Zigong area is accurately predicted.
