【摘要】 观测系统采样均匀性对高精度三维地震采集资料的空间连续性、均衡性,以及对后续资料处理(叠前偏移)和综合解释至关重要。在此提出应用三维观测系统均匀性分析评价方法,通过定性、定量分析三维观测系统的覆盖次数、炮检距、方位角和炮检点分布均匀情况,从整体上对比分析不同观测系统的资料采样均匀性差异,使三维观测系统的选择更加科学、合理。更多还原

【Abstract】 The uniformity of 3D geometry is essential to seismic acquisition in the spatial continuity,balance,as well as follow-up data processing(prestack migration) and comprehensive explanation.In this paper,the analytical evaluation method of 3D geometry is presented to be applied,through analyzing and evaluating the uniformity of 3D geometry on fold,offset,azimuth and offset-fold qualitatively or quantitatively,so as to comparatively analyze the sampling uniformity difference of 3D geometries on the whole,then feed back the analysis results to design process of 3D geometry,make the choice of 3-D geometry more scientific and reasonable.更多还原
