抽油机智能测控系统在油气生产中的应用

Application of Intelligent Control Systems of Pumping Units in Oil and Gas Production

针对油田持续开采带来的低产井增多,抽油机效率下降导致的油井空抽、抽油机磨损及抽油机不能远程操控等问题,自主研发了适用于油气生产需要的抽油机智能测控系统。系统由集配电柜、数据采集柜、变频柜为一体的抽油机智能测控柜(HT-ZNCK)和抽油机智能测控平台组成,除具有数据采集监控、无功补偿、现场语音报警、LED液晶屏就地显示功能外,还增加了基于本地和远程的抽油机启停控制、冲次调节、平衡调节、工频与变频切换等功能。经过在90余口油气井上应用,解决了数据采集不准确、无法调平衡、无法远程控制等问题,实现了油气井的智能排采、智能间抽、柔性闭环控制和无功补偿。提升了油气田企业生产效率,降低员工劳动强度和安全风险,达到稳定产量、节能降耗、提质增效的目的。

Nowdays,there are more and more stripper wells caused by sustained production of oilfields,many oil wells are pumped off due to the decrease in pumping unit efficiency,pumping units are worn excessively and pumping units can’t be remote controlled.For this reason,intelligent measurement and control system of pumping units which are applicable to oil and gas production were independently researched and developed.It is composed of the intelligent pumping unit measurement and control cabinet(HT-ZNCK),which consists of a power distribution cabinet,a data acquisition cabinet and a frequency conversion cabinet,and pumping unit of intelligent measurement and control platform.Besides the advantages such as data acquisition monitoring,reactive power compensation,worksite voice alarm and LED display on the spot,start-stop control,strokes adjustment,balance adjustment,switch over for power frequency/frequency conversion and other functions are added based on local and remote pumping units.Application in more than 90 oil and gas wells shows that the system solved problems that the data acquisition is not accurate,balance cannot be adjusted and remote control cannot be done.Intelligent drainage,intelligent interval pumping,flexible closed-loop control,and reactive power compensation are implemented.Therefore,the production efficiency of oil and gas field enterprises is improved,labor intensity and safety risks of the personnel are reduced so that stable production,energy saving and consumption reducing,and quality and efficiency enhancing are achieved.
