Working Principle and Typical Fault Analysis of Sondex Trator Engage Circuit
The Sondex Tractor is suitable for crawling inside oil pipe and casing pipe.It can carry cementing quality logging instruments,production logging instruments,multi-arm calipers instruments and perforating guns to the target zone for working.It provides a new method for horizontal well logging.The instrument has an independent operating system,which is interconnected with other downhole logging instruments,but does not interfere with each other,and adjusts the crawling speed through the surface system.Based on the analysis of the working principle and typical faults of sondex tractor engage circuit,the paper provides ideas for exploring and researching maintenance techniques for sondex down tractor.
