Influence factor analysis and countermeasures on the system efficiency for the ESP well mixed light oil
Cao Chang（Research Institute of Petroleum Engineering，Northwest Branch Of SINOPEC）2016,6（10）：01-03
Abstract:Blending light oil is an important way of ESP wells lifting in Tahe oilfield，especially for the heavy oil area wells of high yield and large amount of mixing light oil.The system efficiency is an important technical index of the production system for ESP well，and the system efficiency is lower and the energy-consumption is higher in Tahe oilfield.The calculation method of the system efficiency of the Tahe ESP well mixed light oil is determined by the conventional electric pump well.On the basis of this， field testing and calculating system efficiency of the 51 ESP wells mixed light oil，the analysis shows that poor efficiency of down hole is the main reasons on the lower efficiency of
electric pump well system， \horse drawing small cart\the main problem existing in the field of ESP wells mixed light oil.Reasonable design of pump discharge and head，improving the wellbore fluid flow and the application of energy-saving technology can help to improve the system efficiency of pumping wells.
Research on the system efficiency improved by optimizing the pole

Abstract：Pumping unit system efficiency is a comprehensive index to reflect effective lifting machine mining system.Pole impacting on system efficiency is rank only second to pump in the efficiency of each node.The system efficiency can be increased by the theoretical calculation and practical testing the effect of the optimization combination and the rod string length to the system efficiency.10 wells have been tested at field. The system efficiency can be increase by 1.8%. Key words：system efficiency；rod load；rod combination；rod length
Analysis on factors influenced system efficiency of pumping wells
Zhao Shiguang(No.2 Oil Production Plant,Daqing Oilfield Limited Company)2016,6（10）：07-10
Abstract：The oil well system efficiency can reflect not only the power
consumption,but also the comprehensive efficiency of the whole pumping system.It is a parameter that must be paid attention to in energy-saving management.The calculation formula for oil well system efficiency is complex,and there are many influence factors,and each influence factor is mutually restricted.Through the analysis,the relationship between various factors has been cleared,the effects of different models and the pump on the efficiency of the system has been determined.These results showed that the active power for oil well is increased with the increasing of liquid production,the system efficiency of the oil wells were also improving with the deepening of the dynamic liquid level and the basis for selecting pump type and model can be provided.
Key words：system efficiency;dynamic liquid level;daily fluid output;active power
Application of energy-consumption value in oil well production
Xing Yongjun(No.2 Oil Production Plant,Daqing Oilfield Limited Company)2016,6（10）：11-14
Abstract：The energy-consumption plays an important role in oilfield production.The depth of the dynamic liquid level,the cleanliness of the shaft,the energy-consumption test position and the operation parameters for field equipment are analyzed and the influence factors
