Strata反演技术及其在煤矿采区岩性描述中的应用
|
摘要
地震波阻抗反演是岩性地震勘探的重要手段之一。利用钻孔测井数据纵向分辨率很高的有利条件,对井旁地震资料进行约束反演,并在此基础上对孔间地震资料进行反演,利用三维地震资料具有大面积密集采集信息的优势,从平面和立体角度研究煤层厚度及顶底板的岩性变化,推断煤系地层岩性在平面上的变化,大大提高了三维地震资料的纵横向分辨率及对地质问题的研究程度。该文介绍了Strata反演软件的原理和流程,通过实际煤矿采区地震勘探资料的处理与分析,在大量统计数据的基础上,建立了不同岩性与波阻抗之间的解释标准,说明了该方法在岩性描述中的良好应用与成果。
Seismic wave impedance inversion is one of important means of lithological seismic exploration.By means of high vertical resolution of borehole log datum,the well constrained inversion of seismic data is carried out,and on the basis,the hole seismic data is inversed,because three-dimensional seismic data has the advantage of widespread intensive collection information,the lithological change of coal seam thickness and roof floor is studied from the angle of plane and stereo,the coal lithology change is inferred in the plane,so it greatly improves the seismic data vertical and horizontal resolution and the studied degree of geological problems.The principle and process of Strata inversion software is introduced in the paper,through the seismic exploration data processing and analysis for the actual coal mine,the interpretation between different lithology and wave impedance is established based on large statistics numbers,it shows the method have good application and effect in the lithological description.
