Study And Application Of Low Energy Consumption And Sucker Rod Oil Recovery Technology In SuiJing Oilfield

Rod pumping is a very systematic way of mechanical oil production. Rod pumping system is composed of formation, wellbore, surface equipment of three parts. To maintain a rod pumping system energy efficient work, the work of the three subsystems must be coordinated. As with the development of in-depth, formation pressure, production of gas-oil ratio, water content and other production parameters, will result in the system does not work coordination, the need for production wells diagnosis, redesign inefficient wells, pumping parameters and change machine rod pump combination.Beam pumping unit can be divided into conventional type, lead type, heterogeneous type and other types. Based on the conventional type, pre-pumping unit movement characteristics, this paper established the appeasement of oil companies now use the three new oil pump and torque movement of the mathematical model law.In fitting well into the dynamics based on the use of API rod design, the systematic establishment of a rod pumping optimization design method.The preparation of a "system efficiency evaluation and design software." Describes software installation and operation, principles, functions and use processes.Minimum rod pumping system energy consumption design technology to establish a set of rod pumping system input power calculation method to a rod pumping system input power into effective power, ground power losses, viscous losses underground power, underground slide loss of power, and the dissolved gas expansion power of five parts, each part of the power of the factors affecting the pumping system to determine the input power and physical parameters, inclination parameters, device parameters and production parameters of the functional relation between. According to the relation between input power calculation, proposed taking the lowest energy consumption or to the cost objective function Ji Zuidi mining system design method the method is used machine mining Shenshu optimization, Nenggouqueding adopted the most economic machine parameters Zuhe.A "system efficiency evaluation and design software" designed to target machine production system yield the same premise in a more conventional design method using a system designed, can significantly improve system efficiency, reduce energy costs apheresis; can extend well check period, reducing the cost of oil well operations.Field application of reactive power compensation, YCY200L-12 low speed motor, DJNB-3YS pumping energy to run the controller, God King Saver, CQ-YQY-type cluster well pumping unit centralized control of energy-saving control cabinet, crank Last balanced pumping unit transformation, YTZ Series more efficient energy-saving electrical power, machine production system frequency measurement and control devices such as the eight supporting technology, formed for the improvement of machine oil on the appeasement efficient and effective measures taken.
