Studying surface structure in desert areas using multiple kinds of surface wave data

浅表面波浪方法主要在非荒芜的区域在环境、工程的地球物理为表面速度结构的调查被使用。为 Takelamagan 荒芜的区域的特殊地质的特征，我们使用处理多信道的浅表面波浪的方法记录在荒芜的区域决定近的表面速度结构的表面波浪(MASW ) 的多信道的分析。我们也处理，分析，并且比较在从在区域的油探索射击集合提取的许多踪迹记录的表面波浪。我们证明 MASW 方法能决定在荒芜的区域和许多踪迹记录的详细浅速度结构能被用来变得详细深地质的结构。二不同数据集的联合能获得准确速度结构上面在调查区域的 60 m 深度。

Shallow surface wave methods are mostly used for investigation of the surface velocity structure in environmental and engineering geophysics in non-desert areas. For the special geological features of the Takelamagan Desert area, we use the multi-channel analysis of surface wave （MASW） method to process multi-channel shallow surface wave records to determine the near surface velocity structure in the desert area. We also process, analyze, and compare the surface waves in many-trace records extracted from the oil exploration shot gathers in the area. We show that the MASW method can determine detailed shallow velocity structure in desert areas and the many-trace records can be used to get detailed deep geological structure. The combination of the two different datasets can obtain the exact velocity structure upper 60 m depth in the survey area.
