摘　　要：目前水平井、大斜度井对井斜、方位等参数的测量要求越来越高,但公司连续测斜仪因老化、井况差等原因故障率越来越高,且仪修人员紧缺。针对此现状,探索优化维修过程,提高维修效率的方法。通过查阅相关书籍资料,总结了BDS连续测斜仪的物理测量原理、仪器组成、信号变换原理,并基于大量的维修经验,对该仪器三种常见故障现象进行了分析,并提出了相应的处理方法。基于这些仪器原理和故障处理方法,至今已维修了8支积压故障BDS,5支新返还故障BDS,每支维修时间不超过1h。维修过程得到优化,维修效率得到提高。充分理解仪器原理,系统总结维修经验,为维修技术的提高打下坚实的基础。At present,measurement requirements of deviation,azimuth and other parameters for horizontal wells and highly deviated wells are becoming higher and higher.However,the company's continuous inclinometer has a higher failure rate due to aging,poor well condition and other reasons,and there is a shortage of maintenance personnel. In view of this situation,the methods of optimizing maintenance process and improving maintenance efficiency are explored. By consulting relevant references,the measurement principle,instrument structure and signal transformation principle of BDS continuous inclinometer are summarized. Based on a lot of maintenance experience,three common fault phenomena of BDS continuous inclinometer are analyzed and corresponding treatment methods are put forward. Based on the principle of these instruments and fault treatment methods,eight backlog fault BDS and five new fault BDS have been repaired,each of which has a maintenance time of less than 1 hour. Maintenance process is optimized and maintenance efficiency is improved. Fully understanding the principle of the instrument and systematically summarizing the maintenance experience lay a solid foundation for the improvement of maintenance technology.
