华北盆地西部是我国主要的含油气区之一,地震勘探在发现各种油气圈闭中起了重要的作用。现在,那些地震地质条件较好的沉积凹陷勘探程度已经很高,近年来出现了勘探效果逐年下降的明显趋势。因此,本区今后的地震勘探该怎么搞,这是许多人关心的问题。本文在总结以往实践经验的基础上,阐述了对一个箕状凹陷应遵循的正常的地震勘探程序,同时,提出了为改进地震野外资料采集、资料处理和资料解释的质量,当前应采取的主要技术措施。
The western part of North China Basin is one of the major hydrocarbon-bearing areas in China. Seismic exploration plays an important role in the discovery of various oil and gas traps. At present, the degree of exploration for sedimentary sags with good seismic geological conditions is already very high. In recent years, there has been a clear trend that exploration results have been declining year by year. Therefore, the future of the area how to engage in seismic exploration, which is the concern of many people. On the basis of summarizing the past practical experience, this paper expounds the normal seismic exploration program to be followed in a graben-sag. At the same time, it proposes some suggestions to improve the quality of seismic field data collection, data processing and data interpretation. Technical measures
