中国东部地区在油气勘探上是相对成熟的老区,已获得丰富的油气资源,同时也是当前扩大油气储量、迅速提高产能的最现实地区。但是,本区地质构造、岩性岩相复杂多变,给地震工作带来了很大的困难。根据东部含油气区的油气分布规律、地质构造特点,我们对加深该区的地震勘探工作提出一些建议;以新的思路评价含油气圈闭带;提高野外采集精度、搞好精细处理,编制准确的构造图;推广三维地震和垂直地震剖面法,以期在今后几年内获得更多的油气后备储量。
The eastern part of China is a relatively mature old area in oil and gas exploration and has acquired abundant oil and gas resources. It is also the most realistic area for expanding oil and gas reserves and rapidly increasing production capacity. However, the geological structure and lithologic facies in this area are complex and changeable, which brings great difficulties to the earthquake work. According to the distribution pattern of oil and gas in the oil-bearing area in the east and the geological structure characteristics, we put forward some suggestions for deepening the seismic exploration in this area. Evaluating the oil-gas trap with a new train of thought, improving the accuracy of field acquisition, fine processing and accurate compilation Structure map; promotion of three-dimensional seismic and vertical seismic profiling method, with a view to get more reserves in the next few years.
