摘要
将系统概念应用于潜油电泵机组的诊断,将电泵机组分解成3个子系统。结合系统的特点,综合这3个子系统所构成的诊断模型,提出了潜油电泵机组的综合诊断方法。根据系统工程理论,对潜油电泵、潜油电机等井下机组的运行工况、特性、技术参数以及油井地层资料、生产资料、井中流体资料等进行了综合分析,并根据电流卡片、水力实验数据,建立了潜油电泵井下机组综合诊断模型。采用对比测试法,利用电流卡片、井下数据采集及远传技术,计算出井下潜油电机和潜油电泵运行的相关参数。与潜油电泵特性参数相比较,可以实现对潜油电泵机组的综合诊断。
The concept of big system was applied to the synthetic diagnosis of the electric submersible pump （ESP） unit. The ESP unit was divided into three sub-systems. The diagnosis models of the three sub-systems were synthesized. The synthetic diagnosis method for the ESP unit was proposed. On the basis of the concept and theory of system engineering, the working condition, the characteristics and technology parameters of the underground units such as ESP and motor, as well as the stratum data, production data, liquid data of oil wells were analyzed. By using the recording charts and hydraulic experiment data, a synthetic diagnosis model for ESP unit was built. The correlative parameters of the ESP and motor working underground were computed and compared with the special parameters. Using contrast and test method and recording charts for synthetic diagnosis of ESP unit,and technology for data collection and remote transmission of downhole well,The synthetic diagnosis for ESP unit was realized.
