摘要
准中沙漠区地表为沙漠覆盖,地表和低降速带变化大,造成了严重的静校正问题。应用层析反演静校正,导致其存在严重的"窜层"现象,本文分析了产生这种现象的原因,并根据工区近地表特点,论证了时深量板静校正技术的可行性,由此得出该区静校正问题的技术对策,对其他类似地区的静校正技术应用具有指导作用。
The surface of the center of Junggar Basin is covered with the desert, the surface and low velocity zone changes greatly, which result in a serious static correction problem. The application of the tomographic inversion static correction caused a serious occurrence of ＂communication between zones＂. The reason caused the occurrence are analyzed in the paper, and the feasibility of time-depth template static correction are demonstrated according to the characteristics of the near surface, by which the techniques to solve the static correction problem are developed, it provides guidance for the application of static correction in other similar areas.
