【摘要】 地震资料处理结果往往受到地震资料品质的影响,改善地震资料的品质是提高处理解释精度的前提。深水地震资料由于受潮汐和水速变化的影响,资料品质较差。针对此现象,提出潮汐校正和水速校正方法来改善深水地震资料品质,并通过对南海某深水工区实际地震资料的处理与分析,验证方法的有效性和可行性。更多还原

【Abstract】 In seismic data processing,the results tend to be seriously affected by the quality of seismic data. Thus,improving the quality of seismic data is a premise of improving processing and interpretation accuracy,which can provide more effective geological information and data assurance for reservoir interpretation and prediction. Due to the impact of changes in tides and water velocity,deep-water seismic data quality is poor. This paper proposes two methods( tidal calibration and water velocity correction) to improve the quality of deep-water seismic data.The processing results of real deep-water seismic data on the South China Sea show that the proposed method can greatly improve the deep-water seismic data quality,and verify the effectiveness and feasibility of the proposed method.更多还原
