【摘要】 把地震属性技术和地震相分析技术应用于煤层冲刷带的解释工作中。首先从煤层反射波中提取了多种地震属性;然后分析对比地震属性与煤层冲刷带的响应特征;最后利用响应特征明显的地震属性对煤层冲刷带进行了综合解释,确定了煤层冲刷带的范围。与传统钻探解释方法相比,地震属性方法能够更准确地圈定煤层冲刷带的边界。更多还原

【Abstract】 Both seismic attribute technique and seismic facies analysis were used in the interpretation of coal erosion zones.Firstly,attributes were extracted from the reflection of the coal seam.Secondly,these attributes and the response characteristics of erosion zones were comparatively studied.Finally,the erosion zones were explained synthetically with attributes of sensitive response,and the erosion was determined.A comparison with the traditional method of drilling shows that the seismic attribute method can locate the coal erosion boundary accurately.更多还原
