Improve The Screw Pump Wells In Fuyu Oilfield Production Potential Technology Research

The Fuyu oil field began to screw pump test since 2000. In 2004 with the Fuyu oilfield scale well network adjustment screw pump oil production has been large-scale applications. Large scale application of screw pump and achieved good economic benefits, but due to the ground conditions in part area of Fuyu oilfield productivity construction limited, a gradual increase in the number of directional wells in Fuyu oilfield, has formed the characteristic of "shallow directional well borehole conditions", has brought great difficulties and challenges to the normal use of the screw pump. This study from the screw pump in Fuyu oilfield production data collected data of the analysis of the present situation, the establishment of the database of screw pump well, to achieve fast query, classification, calculation, processing more than 1000 screw pump oil well static data and dynamic data. Combined with the characteristics of shallow directional well trajectory ", with the relevant theoretical basis of mechanics of materials and other mechanical, established the dynamics model of pumping rod of screw pump well, able to calculate the dynamic characteristics of different time of sucker rods and the corresponding load and torque. According to the screw pump wells in various parts of the motion characteristics and energy losses, a screw pump system efficiency analysis model of well. Based on the above theoretical research, put forward the optimization method of screw pump wells pumping parameters, and the Fuyu oilfield 20 screw pump production wells and reasonable process parameters are optimized, greatly improving the efficiency of the system, and achieved good results. Through the study of this project, the formation of the optimization design software of oil wells in Fuyu oilfield is a set of process parameters of screw pump, including data management, well productivity prediction, calculation, optimization design, well system efficiency of screw pump production system diagnosis of production system five big modules, and provides technical support to improve the potential productivity and technology for screw Fuyu oil extraction pump.
