GEOWAVES系统采集单元GAU的维保 2 GAU 的维保 2.1 GDU 的维保 GDU 主要由4块电路板组成，维保中主要检查各种信号 是否正常，芯片是否存在虚焊、松动；芯片固定螺丝是否紧固，开关管绝缘垫、绝缘环是否完好等。2.2 GSU 的维保 仪器推靠部件和动密封部分与井液接触，容易出现问题，GSU 部分的拆卸、关键部件维保及...
垂直地震剖面法(VSP)是一种地震观测方法,它是在地表或井口附近的一些点上激发地震波,在沿井眼不同深度布置的一些检波点上进行观测.VSP技术是一项高科技综合系统技术,研发,制造及服务成本较高,因此做好日常的维保,保证仪器完好性对降本增效具有十分重要的作用.作业中各种故障随仪器多次使用开始出现,造成经济损失,尤其...
