静校正方法和装置
摘要：
本申请实施例公开了一种静校正方法和装置。所述方法包括：选取工区的至少一个指定炮点；对于所述至少一个指定炮点中的每个指定炮点，基于该指定炮点中地震道的偏移距和初至时差，计算该指定炮点处的表层速度值；基于所述至少一个指定炮点中每个指定炮点处的表层速度值，生成工区的表层速度模型；基于工区的表层速度模型，对工区的水平基准面进行静校正。本申请实施例可以提高水平基准面静校正的精度。
摘要（英）：

The embodiment of the invention discloses a static correction method and device. The method comprises the steps that at least one specified shot point of a work area is selected; as for each specified shot point of at least one specified shot point, the surface velocity value of the specified shot point is calculated based on the deviation distance and the first arrival time difference of the seismic channel in the specified shot point; the surface velocity model of the work area is generated based on the surface velocity value of each specified shot point of at least one specified shot point; and static correction is performed on the horizontal reference surface of the work area based on the surface velocity model of the work area. The static correction accuracy of the horizontal reference surface can be enhanced by the static correction method and device.
