摘要: 为了提高潜油电泵系统管理水平,提高电泵寿命,降低躺井率,从电泵系统生命周期的11个阶段,优选出9个"可量化、可控制"指标,并按照指标值与电泵寿命的相关性,赋予不同的权重及分值,以评价电泵运行状态,根据评价结果将电泵划分为优秀、良好、正常、危险及高危5个状态.根据风险评价结果,电泵系统管理中采取2个方面的工作:(1)分析电泵运行状态欠佳的影响因素,并采取相应的生产管控措施;(2)在选井、选型配套及设计等电泵系统管理前端,对指标参数进行优化控制.近2年的现场应用结果表明,该风险评价方法能够较客观地反映电泵系统运行状态,用于指导电泵井系统管理,有助于提高运行寿命,降低躺井率.Abstract: In order to improve the management level and life of electric submersible pump (ESP) and to reduce lying rate, technicians selected nine "quantifiable and controllable" indicators from the eleven stages of ESP system life cycle. According to the relevance of index value and ESP life, the indicators were given different weights and scores to evaluate the running state of ESP. The ESP state was classified into excellent, good, normal, risk and high risk. Two aspects of works should be done in ESP system management. 1) Analyzing the factors influencing ESP running state, and taking the corresponding measures of production management and control; 2) Optimizing index parameters when selecting well, matching and designing ESP system management. Field applications in the past two years show that this method can objectively reflect the operation state of ESP, help to improve ESP operating life, and reduce lie well rate.
