Fault analysis and treatment of multi-function pusher
The multi-function push-pull instrument often fails in wireline logging operation,which Has great influence on the actual operation.The time of failure is accidental and difficult to locate.To solve this problem,this paper proposes a systematic analysis idea.According to the working principle of the instrument,it investigates its external influencing factors(ground communication,ambient temperature,external power supply)and internal influencing factors(circuit Hardware and code software),and finally locates the defects in the program design of the instrument itself,resulting in the instability of the equipment.After the circuit program is corrected,the performance of the instrument is normal,and there is no fault in sea operation.
