摘要
Abstract
The complex piedmont zone with good reservoir conditions is an important field of oil and gas exploration. However, the seis⁃mic data have a low signal⁃to⁃noise ratio and poor imaging accuracy because of the complex surface and near⁃surface and subsurface structure. Based on the shooting characteristics which exist in the gravel area of piedmont zone the authors consider that we could con⁃duct points design with the aid of Google Earth platform during the process of selecting piedmont shooting points. The principle of selec⁃ting low areas instead of high areas, gravels instead of rocks and flattened places instead of steep places should be adopted during the selection of shooting points. Tomographic inversion technique goes for the investigation of the piedmont surface layer. The well depth de⁃sign should be shot in the areas with high speed, strong shooting energy and high excitation frequency. The data acquisition of ZD dis⁃trict indicates that the shooting way of the piedmont gravel area adopted in this paper can improve the quality of seismic data.关键词
