海洋石油地质勘探工作中钻井成本十分昂贵,据中国南海东部石油公司统计:1984年的平均成本为758万美元/口井;1986年的平均成本为616万美元/口井。而海上地震工作不仅成本低廉(包括采集处理350～450美元/千米),而且接收条件好,剖面质量高,作业速度快,加之运用大型计算机处理和人机联作解释绘图工作站,成果精度高,速度快,质量好。
Drilling costs are very expensive in offshore petroleum geology exploration. According to the statistics of the eastern South China Sea oil company, the average cost in 1984 was US $ 7.58 million / well; in 1986, the average cost was US $ 6.16 million / well. Offshore seismic work is not only cheaper (including acquisition and processing of 350 ~ 450 US dollars / km), and the receiving conditions are good, high profile quality, fast operation, combined with the use of large computer processing and human-computer interaction interpretation of the drawing workstation, the results of high precision , Fast, good quality.
