| 摘 要： | 射静校正技术在解决杭锦旗地区静校正问题方面取得了一定效果，但折射静校正方法在应用上存在较大的局限性，不同地貌和表层结构的地区，静校正方法有较大差异。本区天然气主要富集在低幅度构造，合理的静校正能使低幅度构造可靠定位。通过对杭锦旗地区特殊地貌与表层结构的分析，认为两者之间有一定的对应关系。在折射静校正处理中应针对不同地貌特征建立初至拾取原则和初始速度模型，以确保折射静校正结果的准确可靠。

| Abstract: | The application of refraction statics has achieved certain effects in Hangjinqi area. However, the results vary with the topography and near surface structure. Low amplitude structures are the main reservoir spaces in this area, and proper statics is a prerequisite to reveal the low amplitude structures. This paper showed there are some correlations between topography and near surface structure. The results have been used to guide the pickup of first breaks and to construct initial velocity model for refraction statics. |
