静校正在准噶尔盆地三维地震数据处理中的应用

准噶尔盆地地表多 为沙漠、戈壁,油气构造埋藏较深,地层相对复杂,褶皱较为强烈,断裂类型多,断裂系统异常复杂。常规的地震资料处理往往得不到好的地震记录。因此,在地震资料处理中应用了多种静校正方法,在准噶尔盆地腹部某地区地震资料处理中的应用结果表明,采用“纱丘曲线法”和折射静校正法对解决复杂地区的静校正问题是可行的,有效的。

An Application of Static Correction Methods in 3D Seismic Data Processing from Junggar Basin

Junggar basin is mostly covered by Gobi and desert, in which petroleum structures are buried deeply,characterized by relatively complicated strata,more serious fold, multiple types of faults and extremely complicated fracturing systems. So using conventional seismic data processing method tends to giving poor seismic records. For these reasons, this paper presents several static correction methods and put them into field application in hinterland of Junggar basin. The results showed that “done curve method” and static refracted correction method would be more effective and practicable to solve the problems existed in static corrections.
