目前多次覆盖在地震勘探中已取得良好效果,而且愈来愈完善,应用愈来愈广泛。但是在山区,由于等距布井受到地形的限制,特别是山上激发条件差,给大量应用多次覆盖带来一定困难。尤其,当前没有大量使用电子计算机处理资料的情况下,山区的不等距炮点、弯曲测线多次覆盖更为困难。相形之下,单次弯曲测线在山区的地震勘探 At present, many times coverage has achieved good results in seismic exploration, and more and more perfect, more and more widely used. However, in mountainous areas, equidistant wells are constrained by the terrain, especially the poor excitation conditions in the mountains, which brings some difficulties in covering a large number of applications multiple times. In particular, at present, it is more difficult to measure the non-equidistant shots in the mountainous areas and to cover the curved survey lines multiple times without using large amounts of computerized data. In contrast, a single curved line survey in the mountains of seismic exploration
