12型斜直井抽油机主体结构与动力设计分析 摘要：在难于建造底座的浅海、沼泽地、河流、湖泊地区，以及在城市大型建筑底部开采石油时，若从陆上或其周围向这些地区底部钻斜直井，可免去在水中建造昂贵的人工岛和避免城市建筑损坏与环境污染。可见在这些场合采用斜直井开采技术必将带来显著经济效益， 该机结构简单，结实可靠，操作维修方便，通用性好，适应性强.具有倾斜连杆机构换向，以倾斜的对准斜直井轴线，并做上下往复循环以适应不同的角度斜直井采油. 采用斜直井抽油机在斜直井上采油，对油田油井二次和三次加密及开发地貌复杂的油田具有重大意义.演算了抽油机的平衡，计算了平衡重；分析了悬点的静载荷，动载荷及最大最小动载荷；分析设计了抽油机的减速系统，对所设计的轴键，轴承进行了强度校核;并对所设计的抽油机进行了经济性分析。 关键：抽油机；斜直井；动力；设计 12 type inclined vertical Wells pumping subject structure and power design analysis Abstract： In the difficult construction of the base of the shallow water， marshes， rivers， lakes region， and the bottom of large buildings in the city when the exploitation of oil， from the land or around the bottom of these areas to drilling straight hole， the water can be removed from the construction of expensive city building artificial islands and to avoid damage and environmental pollution. Can be seen on these occasions with straight hole mining technology will bring significant economic benefits， the aircraft structure is simple， robust， reliable， easy operation and maintenance， common good， strong adaptability. With a rake for the linkage to tilt alignment straight hole axis， and cycle back and forth up and down to accommodate different angles straight hole oil. with straight hole in the inclined straight Inoue pumping oil， oil wells on the second and third encryption and development landscape of great significance to the complex field. calculus of the pumping unit balance， calculate the balance weight; of the suspension point of the static load， the maximum and minimum dynamic load and dynamic load; analysis and design of the pumping unit of the deceleration system， designed shaft key， bearing a strength check ; and pumping units designed for economic analysis.
