摘　　要：在详细分析了转换波资料特征的基础上,以苏里格气田实际采集的多波资料为对象,开展了极性反转、转换波静校正、叠前噪声压制、共转换点道集的抽取等关键处理方法的研究。提出了PS波构造相似法转换波静校正、分频噪声压制技术及共转换点道集抽取解决方案,实际资料的处理结果表明了该方法的正确性及有效性。Based on the detail interpretation of converted wave characteristic data and by taking converted wave data acquired in Sulige Gas Field as object of study,it carried out the study of several key techniques,such as polarity reversal,converted wave static correction,pre-stack de-noising and sorting CCP gathers.The problem-solving plan was put forward,including converted wave static correction based on PS wave structure resemblance,frequency-divided noise attenuation and sorting CCP gathers.The processing of actual converted wave seismic data shows that the methods are correct and effective.
