| 摘 要： | 三维地震勘探取得可靠数据的前提是获得最佳的的激发参数,即激发井深和激发药量。双井微测井是一种行之有效的确定激发参数的方法。以某区25m双井微测井为例,介绍了通过不同激发井深的接收排列图及频谱分析图确定潜水面位置及最佳激发深度的方法;在确定的最佳激发层位上进行不同药量试验,结合目的层有效波时窗频谱图,综合考虑有效信号、地震子波频谱及信噪比等因素选择最佳激发药量。通过双井微测井工作,最终确定潜水面位置为6m,最佳激发深度为11m,激发药量为2kg。

| Abstract: | The 3D seismic exploration is one of most accurate exploration methods in coalfield,which has been widely used in coal and gas exploration.One of the most important processes in 3D seismic exploration is the choice of parameters which include shooting well-depth and shooting dose.The choice of the explosion parameters whether reasonable or not will has direct impact on accuracy.With the improvement of seismic exploration technique,quantitative definition is required in the choice of parameters in field work... |
