Application Abstract: To research the unity-coupling dynamics problem of beam pumping unit by variable-speed-driving(VSD),we select prime motor、rod pump、rod-tube-fluid and oil pump as the research object and adopt multi-points dynamic testing technology to measure the multi-parameters of motor power,net torque of gearbox,load of rod,suspension velocity and pump efficiency.So,we will set up the unity-coupling dynamics models including kinetic characteristic of rod pump,damping vibration of rod-tube-fluid,and fluid-structure interaction of pump valve.We will reveal the energy-saving mechanism of rod pump by VSD and thereby set up a VSD optimizing method and an evaluation methodology for the comprehensive performance of rod pump.The main research contents are as follow:study on coupling dynamical model and calculation method of rod pump with VSD;study on energy-saving mechanism and evaluation methodology of rod pump with VSD;analyze the comprehensive performance of rod pump with VSD by experiments.This research will reveal the action mechanism of the unity-coupling dynamic system property,the kinetic characteristic of rod pump,the forced vibration performance with damp of rod-rube-fluid and the start-stop performance of pump valve,and will achieve the period track curve of the driving velocity,and will establish a comprehensive performance evaluation method of rod pump.This research belongs to the basic theory research for the energy-saving technology of rod pump,and has significant application background and development demand in oilfields.

项目结题报告(全文)

游梁式抽油机变速运行节能技术在国内外多个油田均有应用，该技术的目的是降低悬点载荷和能耗，增强采油装备的系统性能，但实际应用中有些油井出现了平衡差，超扭矩，泵效低等现象。现有变速节能技术偏重于工程应用，缺少相关基础理论和节能机理研究。针对全周期变速驱动游梁式抽油机所引起的全耦合动力学问题，以电动机—抽油机—杆管液—抽油泵为研究对象，采用多节点动态同步测试技术，开展电机功率、减速器输出扭矩、杆柱载荷、悬点速度和泵效等多参量瞬态同步测试研究，具体研究成果：考虑惯性载荷的影响，依据扭矩因数和悬点载荷建立曲柄轴处的扭矩平衡方程；根据电机特性计算获得曲柄的变角速度，得出曲柄轴的变角加速度，完成变速运行时的惯性扭矩求解；依据单元体受力平衡条件，建立杆管液三维有阻尼受迫振动力学偏微分方程模型；采用隐式差分格式，编制程序进行了杆管液三维波动方程的求解；联立电动机负载特性函数、四杆机构动力学函数和杆管液三维振动力学方程为偏微分方程组，并互为边界条件进行全耦合动力学方程求解，编制程序进行隐式迭代计算，求解出抽油机井系统多个节点的瞬态参量；以节电率最大为优化目标，以杆柱应力、减速箱净扭矩不超载及泵效不下降为约束条件，对理论计算的电机功率曲线进行傅里叶变换，逐阶展开获得最优电机驱动速度曲线；在游梁式抽油机模拟试验井上，进行变速运行多节点同步测试，验证理论模型的可靠性。该项目属于机械采油节能技术应用基础理论研究，具有重要的应用背景和发展需求。

    • Beam pumping units; Energy-saving; Variable speed drive; Redesignmethod; Gearbox net torque;ROD; MODEL

    Beam pumping units have been widely used in oilfields worldwide due to its simple structure, strong field adaptability, and convenient maintenance. Different energy-saving technologies have also been broadly applied in various beam pumping units. Among these energy-saving methods, the variable speed drive is one of the most acceptable techniques in the oil and gas industry. In this paper, the energy-saving technology of variable speed drives is discussed in detail for beam pumping units pointing out existing difficulties and current research status in kinematics.

  • 3.A review of beam pumping energy-saving technologies

    • 关键词：
    • Beam pumping units; Energy-saving; technology; Balancing adjustment;Redesign method; Gearbox net torque;OIL-WELL

    The beam pumping units applied in oilfield for more than 150 years, because it had the advantages of simple structure, reliable and durable. At present, it is still one of the most important artificial lift methods in the world. Due to the inherent structure of the beam pumping units, the balanced torque curve of gearbox has a bigger fluctuation ratio and negative torque that results low motor efficiency and load impact. Because the motor efficiency is directly proportional to the fluctuation ratio of gearbox torque, many researchers designed many types of energy-saving devices to improve the system efficiency. Therefore, based on the balance theory of gearbox torque, we introduced and discussed some significant energy-saving technologies, such as phased pumping units, dual-horsehead pumping units, shock absorber device, load reducer device, lower barbell pumping units, multi-balance device, flywheel-energy-storage device, variable speed drive device. Meanwhile, we also pointed out the future research direction.
