In this paper based on the unique geometry and mechanical movement of beam pumping unit,we have presented a simple swing equation and computed motorial parameter;meanwhile under the conditions of the static load and inertial load of the polished-rod of a conventional pumping unit,we have also presented on equivalent dynamic model of the pumping unit system and the type-curves of net torque of the crankshaft with the characteristic of inertial counterbalance have been computed;Based on features and mechanical analysis of belt，a simple model for calculating belt transmission efficiency is developed the model can provide a theoretical base for study on the other transient variable of beam pumping unit;the cyclic loading coefficients is defined once and compute the nominal Power of the motor; at last we compare the beam pumping unit and the adjustable diameter and changeable toque pumping unit, based on this a program have been finished，and we also introduce other power saving pumping units.
This graduation project mainly completes through the high accuracy data acquisition, the gain installs on the oil well oil extraction equipment the electric current, the voltage, the temperature, the pressure, the fluid position, the contact surface, the current capacity, contains water data and so on sensor, corresponds the connection with the many kinds of wireless communications (for example GPRS/CDMA) transmits it to the observation and control center, as well as will receive in the central server to the parameter carries on the real-time analysis and the processing parallel intergrowth becomes the database and the curve report form. Is advantageous for the oil field management level to carry on the prompt accurate management to the scene equipment.
This system depends on in the Beijing Kunlun passing condition automation software science and technology limited company's entire center cultural work
controls the configuration software (to be called MCGS) is the platform carries on the development but to become. The main function is the realization compiles the demonstration oil extraction equipment each parameter, and carries on the analysis and processing to it, function and so on printing report form.

本文根据游梁式抽油机四连杆机构的几何关系和运动特点，建立了游梁的摆动方程，并精确计算出游梁式抽油机悬点运动参数；考虑抽油机光杆静载荷和惯性载荷及运动机构的重力和惯性情况，建立了抽油机系统相对曲柄的等效动力学模型，并求出具有动平衡特征的曲柄轴净扭矩；根据抽油机皮带传动特点和力学分析，建立了一种简便的皮带传动效率计算模型，为分析抽油机瞬时工作参数提供了理论支持；重新定义了周期载荷系数计算储电动机额定功率，并以常规游梁式抽油机、调径变矩式抽油机为例，编写计算机程序，实现了重要参数的计算，并绘出关键曲线，由此比较得出了节能抽油机的优点。

文中还对其他节能抽油机进行了简要介绍。

本毕业设计主要完成通过高精度的数据采集器，获取安装在油井采油设备上的电流、电压、温度、压力、液位、界面、流量、含水传感器等数据，用多种无线通讯通信接口（如GPRS/CDMA）将其传输到测控中心，以及在中心服务器将接收到的参数进行实时分析和处理并生成数据库和曲线报表。

便于油田管理层对现场设备进行及时准确的管理。

本系统依托于北京昆仑通态自动化软件科技有限公司的全中文工控组态软件（简称MCGS）为平台进行开发而成。

主要作用是实现汇总显示采油设备的各项参数，并对其进行分析和处理，打印报表等功能。
