Dynamic performance analysis of workover power tong and boom based on AMESim

In workover operations, minor workover operations account for about 90%~95% of the total wellbore maintenance workload, that is, in oilfield workover operations, the longest operation time and the highest use frequency is the tripping operation of pumping tubing and sucker rod [1]. According to statistics, the time spent in tripping operation of oil wells generally accounts for nearly three quarters of the total time spent in workover [2]. Therefore, it is very necessary to improve the efficiency of tripping operation and realize the automation of tripping operation of tubing and rod for improving the mechanization level of oil fields in China and maintaining stable production of oil fields [3]. In the lifting operation engineering, the most important part is the automatic make-up and breakout link. The efficiency and quality of make-up and breakout are determined by the power tong, so it is particularly important to study the dynamic performance of the power tong. In this paper, amesim is used to establish the hydraulic control circuit of the power tong, and the optimal control scheme is obtained by analyzing the performance curve of the power tong under different pressures [4].
