摘要
文章针对SHDT电子线路故障率高的问题 ,介绍了利用CSU -D系统或CCB -C向井下仪器发送命令 ,监视SHDT五种上传字并观察其各位的变化 ,来判断仪器工作是否正常 ,以及仪器工作不正常时故障产生的部位 ,以达到快速检测、排除SHDT仪器故障的目的。实践证明这是一种非常实用的SHDT故障检测法。
Sending commands to downhole SHDT cartridge by CSU surface system or CCB-C test box,we can quickly mointor five sorts upwords of SHDT,locate and troubleshoot failure parts in SHDT cartridge through observing and analysing the bits in upwords frames defined by SHDT system. The method described in this paper is very effective for instrument engineers to check,locate and remove obstacles in SHDT cartridge maintence.
