Abstract:Dynamite source pattern in seismic data acquisition is one of main factors influencing both quality and cost of seismic data. Optimum seismic source pattern is an essential point which field geophysicists pay much attention to. Arrayed dynamite source and slender cylindrical source are analysed respectively in terms of elastic mechanics and perceptual knowledge in field operation. Analyses lead to conclusions that dynamite point source is most suitable to compressional wave exploration, and that array source in plum flower shape is an effective pattern to produce point source effect.
