新型扩展器在海洋勘探项目中的应用

The application of the new type deflector on the marine exploration project

随着海洋地震勘探的发展,OBN配套技术趋于成熟,越来越多的油公司新增了OBN勘探部署任务。OBN作业模式具有高密度、高精度、高信噪比和全方位等特点,采集的地震数据都布设大量高密度炮点,因此,震源船通常需要采用双源模式激发,以提高生产效率并保证正常生产。本文首先阐述了双源震源船所用新型扩展器的技术参数,继而分析了其使用效果,并提出它在实际生产中的优缺点,以期推进新型扩展器的合理设计,从而推动生产效率的提升和设备的安全使用。

With the development of marine seismic exploration,OBN technology is getting to mature,and more and more oil companies increase the demand for OBN exploration.The OBN operation mode has the characteristics of high precision,high signal-to-noise ratio,and full azimuth.The OBN survey always designed with a huge number of high density shots,therefore,a higher production efficiency of the seismic source vessel is required.In this paper,firstly,the technical parameters of the new type expander for seismic source ship are described,and then its application effect is analyzed,and its advantages and disadvantages in actual production are put forward,in order to promote the rational design of the new type expander,thus promoting the improvement of production efficiency and the safe use of equipment.
