摘要
文章介绍了一种大功率电火花震源的工作原理、总体结构及其主电路,给出了其技术参数。阐述了大功率电火花震源在VSP测井中的应用。通过单台震源(200kJ)和组合震源(500kJ)的地震信号对比发现,组合震源的地震波信号幅值为单台震源的3~4倍,其勘探深度可达4km^5km。
The working principles and structure of the high-power sparker are presenteded, its technical parameters are given, and its application in vertical seismic profiling (VSP) logging is introduced. Contrasting the amplitude of the seismic signals produced by the two sparkers, the signal value of the combined sparker(500 kJ) is 3～4 times of that of the single sparker(200 kJ), and the combined sparker’s inspection depth is expected to be 4～5 kilometers.
