摘要

由于三维地震勘探方法的特殊性,煤田三维地震采集的实际施工面积与要求控制的目标区满覆盖面积有很大出入。但矿方在计算成本时,只考虑了目标区,这就使得勘探施工方与矿方产生了经济分歧。针对这种情况,在三维地震采集设计中,在保证满足满覆盖面积的前提下,笔者采用甩检波点方法来减少施工面积,这样既保证了施工质量,又降低了施工成本。
Due to the particularity of the 3D seismic exploration method,there is a large gap between the practical construction area and the controlled target full fold area demanded in the acquisition of 3D seismic exploration of the coal field.In cost estimation,however,the coal mine only takes the target area into account,which results in economic differences between the construction team and the coal mine.Aimed at solving this problem,this paper brings forward a method that reduces the construction area by ignoring some receivers under the premise of guaranteeing the full fold area in designing 3D seismic acquisition,which not only ensures the construction quality but reduces the cost of the construction team as well.
