【摘要】 在地震勘探中,观测系统的设计对提高采集资料的品质起着至关紧要的作用。常规的观测系统设计方案已经无法满足现阶段复杂的地形需求,针对复杂地区提出了基于目的层反射能量二次导数的炮检距设计思路。在地震照明的基础上,构建地质模型进行数值模拟,根据观测系统接收目的层能量最大及效率最高的原则,将积累能量和能量导数结合起来,设计最大炮检距。通过对塔西南复杂山地地区实际资料建立模型的模拟实验,推断出观测系统的最大炮检距,为复杂地区的最大炮检距设计提供了新的方法和手段。更多还原

【Abstract】 During seismic exploration,the seismic survey design takes an essential part in the improvement of acquisition data.Theconventional survey design in the past can not meet the needs of complex seismic exploration,thus an optimal idea of offset basedonsecondderivativeoftargetstratumenergyisdeveloped.Inthisarticle,atthebaseofilluminationwecreatedgeological model,then for the principle of highest efficiency and maximize in the target stratum energy,combining the detector energy with energy rate using accumulation of energy and energy derivative,finally a new method of maximum offset was presented.In this way,the experiment on complex moutainous area in Tarim shows a good result,therefore this design provides a new method and means for the complex area.更多还原
