摘　　要：通过对大民屯凹陷地震资料的详细分析,针对洼陷部位信噪比高、主要目的层沙三、沙四段频率相对较低的特点,研究出一套高分辨率处理技术,主要包括子波处理技术及优势频带约束下的分频处理技术,能满足沙三、沙四段储层横向预测的需要,见到了较好的应用效果。Based on an analysis of the seismic data from Damingtun Sag and in the light of high signal-to-noise ratio in the sag area and relatively low frequency in the main targets S3 and S4, the authors designed and developed a kind of high resolution technology com- posed mainly of the wavelet processing technology and the frequency band separation under the restriction of the FDOM technology. These means can meet the demands of reservoir transverse forecast of S3 and S4, and have already shown good application results.
