【摘要】 电火花震源是海洋工程地震勘探作业中一种较好的震源,但"十五"之前我国的电火花震源主要依靠进口,仪器维护费用高、周期长。"十五"期间国家海洋局第一海洋研究所研制了海洋电火花系统PSS500J,并取得了很好的应用效果。结合PSS500J研究成果,介绍了电火花震源的构架,分析了电火花震源充电技术的两种设计方案,对震源工作中安全保障提出了技术建议。更多还原

【Abstract】 Sparker source is a good type of seismic source used in marine engineering seismic prospecting.Because of the importation dependence before the tenth five-year period,the expense was enhanced and the period was extended of equipment maintenance.In the tenth five-year period,the marine sparker source,PSS500J,was developed by the First Institute of Oceanography of State Oceanic Administration.The effect of the application is good.Combining with the study of PSS500J,the configuration of sparker source is introduced.The two project of the sparker charging technique are analyzed.Some proposals of the safeguard of the sparker source are put forward.更多还原
