“…Therefore, based on mechanism analysis in a sucker-rod pumping system, Zheng et al [ 28 ] drew out seven key parameters, such as the moisture content, gas-liquid ratio, sucker-rod specifications, stroke, speed, pump diameter, and working condition, and identified the working condition using a hidden Markov model. Zhang et al [ 7 ] selected feature data, such as dynamometer cards, power, liquid-producing capacity, dynamic fluid level. Liu et al [ 8 ] extracted the key parameters, such as dynamometer cards, liquid-producing capacity, work day time.…”

“…However, employing one information source easily triggers a complex electron machinery liquid integrating system, producing false alarms. Second, the existing methods' model robustness and recognition performance using multi-source information must be further improved [ 7 , 8 ]. This is because traditional multi-feature connection methods are technically limited from being further improved.…”

“…Если коэффициент неуравновешенности находится в пределах от минус 0,05 до +0,05, то насосная установка считается уравновешенной. И дополнительные потери мощности в этом случае можно не учитывать [26][27][28].…”

“…Therefore, the timely diagnosis and analysis of the production system is important to ensure the safe operation of oil wells and the maximization of the economic benefits of oilfield development [11][12]. Dynamometer card analysis is an important means and effective measure to diagnose the working conditions of sucker-rod pumps [13][14][15]. However, with the informatization construction of oilfields, dynamometer cards have realized online realtime acquisition [16].…”
