| 摘 要： | 柴达木盆地三湖地区富含天然气藏,以往在地震数据采集中多采用突出炮点、检波点组合作用的方法压制和削弱干扰波,难以达到预期效果。如今采用高精度地震勘探,突出观测系统的优化设计,并利用地震数据处理中的水平叠加进行噪声压制,充分提高地震数据的信噪比和分辨率。本文针对目标工区地质任务及地震勘探难点,对比研究噪声干扰特性,剖析以往地震勘探中存在的问题,并论述了叠加响应对高精度地震勘探所起的积极作用,为该区天然气勘探提供高质量、高精度地震数据。

| Abstract: | There are rich gas accumulation in Sanhu area Qaidam Basin.In the past,the composed way of shot patterns and receiver arrays are used to attenuate the noise in the seismic data acquisitions.But it couldn't achieve the expectations.For improving the signal-to-noise ratio and the resolution of the seismic data,the optimized geometries are designed in the high-precision seismic exploration,and attenuate the noise with the horizontal stacking in the data processing today.Considering the geological tasks and the... |
