摘　　要：介绍了新型液力抽油装置的组成及液压驱动系统的工作原理,该装置综合了液压有杆抽油装置和水力活塞泵抽油装置两方面的优点。特别适合于开采沥青质高粘油井以及中、低产量的定向井、水平井等特殊结构的油井,也适用于开采井深超过有杆抽油系统工作范围的油井。这种抽油装置具有结构简单、制造方便、设备重量轻、便于安装等特点,因此具有很强的应用价值。The structure compositions of a new type of hydraulic driving pumping oil installation and the working principle of its hydraulic driving system are introduced.The new pumping oil installation is of the synthetical advantages of rod pumping system and hydraulic piston pumping system. The new pumping installation can be used to pumping asphalt oil of high viscosity oil wells,and it also can be used to pumping oil of some wells which depth is more than the working range of rod pumping systems.Because the installation is of some advantages of simple structure, convenient manufacture, light weight and convenient arrangement, it is of practical using value.
