【摘要】 基于层位数据(或煤层反射时间)在采区三维地震勘探构造解释过程中的重要作用,为充分挖掘地震勘探层位数据中蕴含的有用信息,更精确地解释断层等地质构造,以兴隆庄煤矿某采区三维地震数据体为依据,利用自编软件提取了其3号煤层的层位数据,并利用数值方法计算了其梯度,绘制了解释图件,并进行了构造的二次解释。应用结果表明该方法能使断层的延展更清楚,且大断层的解释不会遗漏,因而提高了断层解释的精度和可靠性。更多还原

【Abstract】 According to the very important role of the horizon data(or the seam reflection time) in the structure explanation process of the 3D seismic exploration in the mining block,in order to fully excavate the useful information in the seismic exploration horizon data and to more accurately explain the fault and other geological structure,taking the 3D seismic data of a mining block in Xinglongzhuang Mine as the basis,the self prepared software was applied to pick up the horizon data of No.3 seam,the gradient was calculated with the numerical method,the explanation drawings were prepared and secondary explanation of the structure was conducted.The application results showed that the method could clearly expand the fault,the explanation of the large fault would not be omitted.Thus the accuracy and reliability of the fault explanation could be improved.更多还原
