【摘要】 目前,油气勘探工作进入到一个"低幅度、小断块、薄储层"的复杂油气藏勘探阶段,对地震资料处理的高分辨率、高信噪比、高保真度和成像准确的要求也越来越高,同时随着叠前深度偏移技术的推广和普及,先进的预处理技术已经成为地震资料处理环节中重要的一环。为了满足"三高一准"的处理要求,选择合适的预处理方法是至关重要的。该次研究通过在松辽盆地南部吉林探区的地震资料预处理过程中,采用SPS格式质控和对比折射静校正相结合的方法提高了处理精度,取得了非常好的应用效果,达到了高精度地震资料处理的要求。更多还原

【Abstract】 At present,oil and gas exploration work entered into a stage of complex reservoir exploration of low-amplitude,small fault block and thin reservoir.The high requirements on high-resolution,high signal-to-noise ratio,high-fidelity and accurate imaging were increasingly needed for seismic data processing,at the same time with the population and introduction of pre-stack depth migration technology,the advanced pre-processing technology has become an important link of the seismic data processing.In order to meet the processing requirements of the above situation,selection of the appropriate pre-processing method is essentially important.In the study of seismic data pre-processing in Jilin Oilfield,combined with the application of SPS quality control and CRM refraction static correction,the processing accuracy is improved,requirement of high-precision seismic data processing is achieved.更多还原
