对于陆上地震采集而言,不同的地表条件,采用的激发因素是有差别的。如何选择最佳激发因素,获得最佳品质的单炮记录,是提高地震剖面质量的关键。从激发的虚反射效应、激发岩性与炸药类型的耦合关系以及子波品质等方面,研究不同地表条件下的激发因素,探讨了最佳激发因素的选择途径,并且通过试验资料来证明理论分析的合理性。
For land seismic data acquisition, the shooting parameters should vary with surface conditions. This paper analyzes the effect of ghost, the coupling relation between shotpoint lithology and dynamite types, and the quality of wavelet, studies shooting parameters in different surface conditions and how to select optimum shooting parameters. Experimental data demonstrate the reasonableness of theoretical analysis.
