【摘要】 老爷庙地区的陆相沉积具有多物源、多沉积体系、水动能变化大、高频率的水进水退、相变快、断层多、断距小、储层薄且横向变化快等特点,且具多旋回、多油层等特征。本文针对该区陆相薄互层的地质特点和地震响应特征,在保持较高信噪比的前提下,给出了薄互层高分辨率分析方法和实现流程。实际地震数据处理结果表明,本文分析方法和流程可有效提高薄互层地层的地震资料分辨率,其结果可用于精细刻画薄互层型地层的空间展布,有利于进行薄储层预测。更多还原

【Abstract】 Laoyemiao oilfield has complex continental deposit characteristics such as multi-provenance,multiple depositional systems,current energy variation,frequent transgression and regression,fast facies change,multi-faults,small displacements,thin beds and horizontally fast changes.These cause a real challenge for seismic exploration in the area.To solve the geological problems,this paper introduces a method for seismic data resolution improvement with wavelet analysis in the condition of keeping high signal-to-noise ratio data,and proposes its implementation procedure.Applications of this method to synthetical data and real field data prove its validity and effectiveness for seismic data resolution improvement of thin interbeds.Its results will be helpful to thin interbed distribution delineation and reservoir prediction.更多还原
