油田勘探开发仪器的不断发展,计算机的普遍应用,对仪器的数据保持电源提出了较高的要求。特别是一些井下仪器,不但要求电池有较大的容量(井下仪器一般在井下时间较长),较稳定的工作电压,且能以较大的脉冲放电、耐冲击,而且还要有很好的耐高温性能(150℃)。电池性能的好坏直接影 The continuous development of oilfield exploration and development instruments, the widespread use of computers, put forward higher requirements on the data holding power of instruments. In particular, some underground instruments, not only require a larger battery capacity (downhole equipment generally downhole time), more stable operating voltage, and can be a larger pulse discharge, impact resistance, but also have good High temperature performance (150 ℃). Battery performance is good or bad direct shadow
