煤矿采区三维地震属性应用中的风险分析与动态解释

RISK ANALYSIS AND DYNAMIC INTERPRETATION IN THE APPLICATION OF 3D SEISMIC ATTRIBUTES IN THE COAL MINING AREA

随着地震属性技术的发展,属性解释面向煤矿采区生产要求的精度,其成果可靠性存在一定风险,这与地震属性应用中存在不确定性和非唯一性有关。笔者着重对地震属性应用风险的影响因素进行了分析;并用实例证明,把三维地震属性信息与矿井巷道揭露的地质信息相融合,实现动态解释,是提高煤矿采区三维地震属性解释成果可靠性的重要技术路径。

With the development of seismic attribute technology,the reliability of the precision of attributes has some risk in meeting the requirements of an coal mining area,which is related to the uncertainty and non-exclusive nature in the application of seismic attributes.This paper has analyzed the factors responsible for the applied risk of seismic attributes and,with examples,indicated that the integration of the three-dimensional seismic attribute information with the geological information revealed in the mine tunnel for realization of dynamic interpretation is the effective means to improve the reliability of the results of 3D seismic attributes in a coal mining area.
