三维地震观测系统无缝拼接技术在镇巴地区的应用
|
摘要
针对相邻区域分期进行地震勘探,使用相同类型的地震采集数字地震仪进行采集,在测线方位角和面元大小一致及观测系统相似的前提下,优化设计出两次三维拼接的观测系统,实现两次三维采集的无缝拼接。保证了地震资料属性分布的连续性,拼接区面元叠加次数、炮检距、方位角分布均匀,避免了重复采集,节约了勘探成本,取得了理想的地震采集资料。
According to the seismic explorations of adjacent areas,by using the same seismic acquisition digital seismometers to ac quisit measuring line,and under the preconditon of same size bin and similar observation system,this paper optimized twice 3D joining observation system and realized twice 3D spliced seamless.This technology guaranteed the continuity of the seismic data at tribute distribution and made binning superposition times,geophone distance and azimuth uniform distributions.As a result,it avoided the repeated acquisitions,saved exploration cost and made the ideal seismic acquisition material.
