为了对一种容易执行并且经济的三维数据采集方法进行评价,开展了地震实验。实验的目的在于(1)确定在其上检波器和震源都不能铺开的地下区域资料采集的方法(即地下放炮under shooting)的有效性。(2)能用于发展三维软件的记录。(3)为了解释的目的获得资料,选择三维工区的准则是:能取得好的信号的地区,具有三维的地质目的层,井的控制以及能进行野外测井。在记录资料之前,标准的测线方向上的波组试验用来确定最佳激发参数,例如炸药
Seismic experiments were conducted to evaluate an easy-to-implement and economical 3D data acquisition method. The purpose of the experiment is to (1) determine the effectiveness of the method of data acquisition in the subterranean area where neither the detector nor the source can be deployed (ie under shooting). (2) can be used to develop three-dimensional software records. (3) For the purpose of explanation, the criteria for selecting a 3D work area are: a good signal area, a 3D geological target bed, well control, and field logging. Prior to recording the data, wave group tests in the standard line direction were used to determine the best excitation parameters such as explosives
