古尔班通古特沙漠位于准噶尔盆地腹部。以往对表层结构的认识局限于表层调查设备的能力，近年来随着钻探力度的加大，对表层结构特征又有了新的认识。通过对空间上分布的新采集的微测井调查资料，分析古尔班通古特沙漠形成机理，表层介质的构成，及各层速度和厚度的变化规律。掌握了其结构特征，对该区建立表层结构模型，精确计算静校正有重要指导意义，能有效帮助静校正计算人员合理构建表层结构模型。实际应用表明，在新认识指导下建立的表层结构模型，有效消除了以往地震剖面中的静校正不同波长问题，为地震资料处理和精细解释提供可靠的数据资源。

Gurbantunggut Desert is located in the center of Junggar basin,In the past,the acquaintance of surface struc-ture is limited by the surface survey equipment ability.With the increasingly drilling effort,a new awareness has been ac-quired.By means of the new collected micro logging data that distributed on the space,anylized the formation macha-nism of the Gurbantunggut Desert,the composition of the surface material,and the varying pattern of each layer’s speed and thickness.Possessed the structure character of Gurbantunggut Desert,and it is meaning for establish the surface struc-ture model and calculate the statics correction accurately,and it is contributed for the staff to establish the surface struc-ture model legitimately.Practical application suggested that the the surface structure model established under the direc-tion of the new awareness,eliminated the different wave length problem in the statics correction of seismic section effec-tively,provided lots of data resources in seismic data processing and exquisite interpretation.
