| 摘 要： | 随着近年地震勘探装备技术的提高,以高空间采样率为显著特征的高密度地震勘探技术取得了重大进展。本文介绍的胜利油田罗家地区陆上高密度三维地震采集试验,首次进行了超万道、全数字、单点、三分量高密度三维地震采集。在区域噪声特征分析的基础上,采用束状正交集中式对称观测系统,提高了采集数据的连续性和均匀性;施工前采用多种手段进行详细的表层结构调查,建立了精细表层结构模型;采集作业中,在改进检波器耦合条件的同时,强化了试验资料和施工记录的现场监控处理分析,获得了高品质的高密度多波资料,探索并形成了高效的高密度超万道地震数据采集组织管理模式。

| Abstract: | With the advance in both field equipment and seismic technology,significant progress of HD(high density) seismic acquisition has been made in recent years.In 2008,Shengli Oil Field of Sinopec has conducted a land HD seismic acquisition in Luojia area.This was the first HD acquisition with over 10,000 live channels of 3C digital sensors in China.We adopted single-receiving technique that means that a single 3C sensor was planted at each receiver point.Based on noise characteristics analysis in the working ar... |
