Research and application of efficiency improvement technology of intelli-gent measurement and control system in oil production well site
In order to improve the efficiency of mechanical production system of pumping well in a certain operation area of oil production plant and achieve energy conservation and emission reduction goals,the re-search has been conducting on the current situation of domestic and foreign mechanical production system.It is found that there are two main problems including insufficient liquid supply,pump evacuation,and excess power consumption of motor in the mechanical production system.Hence,designing and applying the intelli-gent measurement and control system of oil production well site which has important functions containing col-lecting electrical parameter data,calculating suspension point loads,and controlling pumping units.The grey control model for oil well interval pumping that integrated electrical parameters and suspension point loads is proposed,and the hardware design and software flow of the core intelligent measurement and control unit of the system are completed.The on-site application results of the system in 11 oil wells show that it can not only achieve online accurate soft measurement of suspension point load,with good stability and strong engineering practicality,which meets the production requirements of the oilfield site,but it can also achieve automatic control of interval pumping in oil wells,dynamically optimize the interval pumping parameters,and opti-mize the matching between the oil pumping process and the wellbore seepage rule.The average efficiency of me-chanical production system has increased by 2.73 percentage points,with a daily energy saving of 951.5 kWh,which has good engineering application value.
