摘要
针对川南河包场地区目的层埋藏浅,地表激发条件复杂的实际情况,在三维地震勘探设计中,对采用的参数经过严格论证,采用宽方位观测系统设计理念,合理设计接收方式,优化选择激发点位置及井深,利用卫星遥感数据辅助设计改变观测系统,同时采用多种方法进行精细表层调查和建立近地表地质模型,由此得到的三维地震勘探采集资料,其品质与老资料相比大大提高。
On account of the shallow-buried target bed in Hebaochang structure in south Sichuan Basin and the complicated surface condition,3D seismic took advantage of many effective methods,such as the designing method of 3D wide azimuth layout with the proven parameters,the reasonable design for receiver pattern,the optimized selection of the inducing point and well depth,the variable layout designed by the satellite remote sensing data,adopting several methods for fine surface investigation and establishing the geologic model of near surface.Finally compared with the former data,the quality of the 3D seismic prospecting data has been improved greatly.
