【摘要】 本文概括叙述了国内外机械采油技术的现状。指出，许多油井由于产量递减，需要采用间歇式抽油工艺。许多油井处于油田边缘，是电源、输油管道还没通过的地区，需要采用移动式采油设备，因而国内外相应诞生了一种新式采油设备，即移动式抽油机（也称提捞采油车），这对油田的开发和提高油田效益无疑是非常重要的。 通过对大庆油田现在使用的CY2000型移动式抽油机分析和研究，发现设计上还有许多不合理、不完善的地方，在使用过程中也多次发生故障，钢丝绳排列不畅、车身结构不合理、钢丝绳滚筒变形导致停机、效率低、维修不便等，有必要进行彻底地改造，以确保抽油机的正常运转。 移动式抽油机，从总体结构上看，实际上是抽油机与汽车吊的组合，但由于钢丝绳很长，钢丝绳滚筒所缠绕的钢丝绳很多，因而带来了普通汽车吊所没有的许多新问题。 本人在分析CY2000型移动式抽油机工作原理的基础上，提出了改进的设计方案。特别是对滚筒所受钢丝绳的挤压力进行了分析和计算，从理论上找到了滚筒变形破坏的原因，对滚筒本身的结构进行了分析和强度校核。同时选出了钢丝绳排绳的方案，设计了排绳机构。加工出具有排绳机构的新型滚筒，在生产实际应用中证明效果良好，为油田生产解决了实际技术问题。 虽然这次技术改造已大大改观了移动式抽油机的运行状况，但还有许多问题有待解决，文中通过分析也提出了今后继续改进的意见，为研制和完善新型、高效、耐用的移动式抽油机提供了理论基础和实践经验。更多还原

【Abstract】 In this thesis the mechanical production technology and its application at present were analyzed and the swabbing machine (the truck for pulling oil) which can solve the problem of the oil reducing for the low production well the working theory and the necessary for developing. This new technology was demonstrated and also a special drum was designed which can be successfully used in this swabbing machine This had offered the theoretical and practical basis for the research and development of the new swabbing machine This thesis proposes the reforming design schmes. On the basis of analysis of the working principle of the cy2000 swabbing machine. After analysis and calculation of the loading force of the machine. The causes of damage of capstan in theaiy. At also carries analysis and strength calculation of the loading force. Although the reformming has improved the condition of running of the machine there are many problems to be solved .the paper also analyses the possibilities of theory and its application for the swabbing machine of new type high efficiency.. Trough the analysis and research of the cy2000 swabbing machine availabe in Daqin~g of oil- field, there are many improper points of design. and many defaults in the process of application. Steel rope needs properly arrangements. Body structure also needs many improvements. The capstan for steel rope results in abnormal stop and low efficiency. Maintenane for the machine has difficulties as well on general. It is necessary to reform. if thoroughly in order to make the machine run smoothly.更多还原
