随钻中子孔隙度测井仪直流不间断供电模块设计

随钻中子孔隙度测井仪在井下工作时要满足连续工作150～350小时的特殊需求,为了防止出现数据丢失等问题,井下仪器的控制和存储部分要始终保持在工作状态.因此该仪器必须要使用不间断的供电模式.主要介绍根据随钻中子仪器应用需求设计的具有多路输出的不间断供电模块的设计.

While working in the underground,LWD neutron porosity tool have to meet the continuous work 150 to 350 hours of special need.In order to prevent data loss and other issues,the controller and the storage part have to remain in working condition.Therefore,the instrument must use an uninterrupted power supply.This paper focus on design of the uninterruptedpower supply module with multi-output for the LWD neutron porosity tool.
