第一章前言在冷湖地区,已开展了几年的磁带地震助探工作。由于采用了多次覆盖的技术,使之在勘探的效果上比以往有了某些明显的提高。这个地区的野外工作方法普遍采用三多:即多检波器组合(30～60个),多井组合(4～20多口井不等),多次覆盖(6次为主)。这种施工方法除了野外工作进展缓慢以外,从取得的地质资料本身来看,在某些复杂断块地区,仍然不能完整地说明地下地质情况,断层的位置不够准确,层次的划分不够确切,特别是某些测线的时间剖面上有多种方向的波交杂在一起,给解释工作带
Chapter I Foreword In the cold lake region, a few years of tape seismic exploration work has been carried out. Due to the use of multiple overlay techniques, there has been some noticeable improvement in the effectiveness of exploration over the past. The field work methods in this area are generally used more than three: the combination of multiple detectors (30 to 60), multi-well combination (ranging from 4 to more than 20 wells), multiple coverage (6 times the main). In addition to the slow progress of field work, this method of construction not only shows the underground geological conditions in some complex fault blocks, but also the location of faults is not accurate enough and the classification of layers is not exact enough. In particular, Is the time profile of some of the time line with a variety of direction waves mixed together to explain the work with
