摘要
为有效识别采区中陷落柱,提高煤田地震勘探的解释精度,在三维地震数学模型的基础上,设计了相对容易建立的三维陷落柱模型。通过正演模拟,对提取模型数据的地震层属性、方差体属性进行研究、分析、优化与筛选,最终得到对陷落柱反应灵敏的地震属性。将该研究成果应用到某勘探区的资料解释中,解释成果经采掘资料验证,该方法选定的地震属性具有较高的构造识别精度。
To identify subsided columns in winning districts effectively and improve coalfield seismic prospecting interpretation precision, relatively easy to establish 3D subsided column model has been designed based on 3D seismic math model. Through forward modeling, studied, analyzed, optimized and filtrated seismic layer and variance cube attributes used in model data pickup; finally have gotten seismic attributes sensitive to subsided column. Applied the result in data interpretation of a prospecting area, the interpreted outcomes have been testified through mining data, illuminated the selected seismic attributes have higher structure identification precision.
