| 摘 要： | AVO技术是研究反射波振幅随炮检距的变化规律,目前在油气探测中已成为一种十分有效的勘探手段。基于AVO技术在多方领域中的探讨,对在煤层勘探中的应用进行了分析,建立了煤系地层的AVO正演模型,并对其进行了分析研究,认为煤层顶、底板反射波振幅随炮检距的增加而减小。根据不同煤种反射波振幅随炮检距的变化不同还可以估算出煤的种类。

| Abstract: | AVO technology is the study reflected wave amplitude with offset changes in the laws currently in the oil and gas exploration has become a very effective means of exploration.Based on the AVO in the multi-technology in the field of exploration of coal and in the exploration analysis,establishing the model of the coal-bearing strata of the AVO,and analyzed,considering that the coal seam roof and floor reflected wave amplitude with the offset increasing. |
