Zusammenfassung: | The invention provides a method for finely identifying a collapse column by utilizing seismic chaotic body attributes, and the method comprises the steps: innovatively adding a construction guiding filtering technology into seismic data preprocessing before the chaotic attributes are calculated; and comprehensively and finely explaining the collapse column by jointly using the chaotic attribute profile, the horizon attribute and the interlayer attribute. When the seismic time profile resolution cannot meet fine interpretation of the collapse column, the development boundary and height of the collapse column in each coal seam can be effectively described by means of the spatial change of the seismic attribute characteristic value.
本发明提供一种利用地震混沌体属性对陷落柱进行精细识别的方法,在计算混沌属性前,创新性地将构造导向滤波技术加入到了地震数据预处理中;联合运用混沌属性剖面、沿层属性和层间属性综合精细解释陷落柱。在地震时间剖面分辨率不能满足陷落柱精细解释时,依靠地震属性特征值的空间变化,可以有效地刻画陷落柱在各煤层中的发育边界和高度。 |
