从1969年起,我队在苏北的G区,M区和T区,采用共反射点多次迭加法进行了大量的工作,所取得的资料比以往用普通工作方法获得的资料,质量有了很大提高,但离较好地解决该地复杂的地质任务来说,仍有一段距离。为此,我们对上述三地区影响多次迭加效果的主要因素进行了初步的分析,以便提供改进工作方法,进一步提高勘探效果的一些依据。 Since 1969, our team has done a great deal of work in the G, M and T zones of northern Jiangsu using the multiple reflections of the common reflection point. The obtained data are much better than those obtained by ordinary working methods in the past, However, there is still a long way to go to solve the complicated geological task in the area. To this end, we have conducted a preliminary analysis of the main factors that affect the multiple superimposed effects in the above three regions in order to provide some basis for improving our working methods and further enhancing the exploration results.
