海洋天然气水合物调查地震采集技术——潮期羽角预测研究

地震采集技术在野外地震调查中起着举足轻重的作用,特别是对三维地震调查方法的研究。其中对潮期和羽角的研究能够给三维地震调查提供有力的保障,可以起到事半功倍的效果。潮期预测的主要目的在于"通过对作业海域潮位数据的分析,预测一个较长时间段之内(一个月以上)潮汐变化规律",因此,通过研究,可以选择最佳作业时机进行野外采集,为"航次计划"提供基础数据,降低采集费用、提高作业效率。

Seismic Exploration Technology in Marine Gas Hydrate Investigation--Study on Tide Period and Streamer Angle Forecast

Seismic exploration technology is very important for the marine seismic survey, especially in the three-dimensional seismic survey. The research on tide period and streamer angle can provide a powerful assistance. When we forecast the tide period and streamer angle, we can arrange the work for a good time, and can get the rule of tide change. So selecting an available method to investigate the tide and streamer angle is important for the field seismic survey, we can choose the best time for working. It also can reduce the survey charge and enhance the working efficiency.
