Primary Study on Constrained Inversion Techniques in Detecting Coal Thickness

摘要:

现代化矿井生产技术日新月异，尤其对煤层厚度的探明程度要求越来越高。综合利用地质钻探和测井等资料，与地震资料有机结合而产生的具有高分辨率的新方法，发挥了钻探、测井和地震勘探技术各自的优势，实现了不同技术之间取长补短并提取地震属性参数，通过波阻抗约束反演可获得煤层厚度参数，达到对煤层厚度进行预测的目的。

Abstract:

Modern mine production technology has gained many achievements. Precision of proved degree of coal strata thickness has become increasingly highly. Through comprehensive utilization geological drilling and well logging and other information, combing with seismic data, a new method with high resolution has formed. It has played respective advantages in drilling, well logging and seismic exploration technology, reduced different technical errors, and extracted the earthquake attribute parameters. Through the wave impedance constrained inversion, coal strata thickness parameters can be gained, and coal strata thickness can be predicated.
