中文摘要	苏里格气田地表条件复杂,北部为沙漠、草原区,南部为黄土塬地貌,沟壑纵横、梁峁交错。如何解决不同地表类型的静校正问题是地震资料处理的关键。探讨和分析了折射波静校正、走时层析反演静校正和初至波线性拟合静校正等方法在该气田多个工区的应用效果。结果表明,折射波静校正方法对于具有稳定折射层的地区,应用效果较好;走时层析反演静校正是一种非线性反演近地表速度模型的方法,可以有效地解决复杂地区的静校正问题;初至波线性拟合静校正是一种剩余静校正方法,可以进一步解决残余的静校正。因此,解决苏里格气田复杂地表的静校正问题必须根据实际地表地质条件,采用组合静校正,实现多种静校正方法的优势互补和有机组合。
英文摘要	The surface condition of Sulige Gas Field was complex and variegated,its northern part was boundless desert and prairie,and southern part was loess plateau with cross gullies.How to solve the static correction problem was the key factor of seismic data processing.The effect of application of the methods of refraction wave static correction,travel-time tomographic inversion static correction and first break linear fitting static correction were studied and analyzed in seismic data processing of different operation areas in Sulige Gas Field.The results show that for some areas with invariable refracting layer,the refraction wave static correction is a preferred choice;travel-time tomographic inversion is a method that nonlinearly inverts the velocity model of near surface and it is better to solve the statics problem in complicated area;first break linear fitting static correction is a residual static correction,and it can solve the problem of residual statics.To solve the problem in Sulige Gas Field should be Based on the actual surface and geologic conditions,a joint application of static corrections is used to realize the advantage of each staticcorrection,it is a good method for preferably solving static problem of complex surface conditions in Sulige Gas Field.
