一、历史的回顾 HZ构造位于GI凹陷东部,是含油远景评价较高的地区之一。从一九五八年进行地震勘探工作以来,共计完成地震剖面达700多公里。由于该区多次波和火成岩发育严重,资料一直未能过关,经历了几进几出的过程。六七年以前采用普通地震进行工作,尽管对多次波进行了大量的研究工作,其结论是采用“现有仪器 I. Historical Review The HZ structure is located in the eastern part of the GI depression and is one of the regions with high oil potential assessment. Since the seismic exploration work in 1958, a total of more than 700 kilometers of seismic profiles have been completed. Due to the serious occurrence of multiple waves and igneous rocks in the area, the data have not been able to pass through and the process has gone through a few steps. Ordinary earthquakes were carried out by six or seven years ago, and despite extensive research on multiple waves, the conclusion was that "existing instruments
