XCYJ10－3－37HB斜直井抽油机设计

Model XCYJ10-3-37HB pumping unit for sthaight slant holes

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。为了满足大庆地区斜直井采油需要，研制了１０型０～４５°斜直井通用抽油机。其主要特点是：把抽油机将要适应０～４５°井斜角分为四段，按抽油机四连杆机构优化设计原理，分别给出各段四连杆机构最佳数据，运用组合设计方法，将得到的四组四连杆机构数据组合设计在一台抽油机上，使其具有四个机位状态。通过对机位状态的调整，可适应０～４５－°范围内任意井斜角的油井，而抽油机本身又能在最佳状态工作。

To meet the need of oil production on straight slant holes in Daqing oil field, Medel XCYJ10 - 3- 37HB pumping unit for slant holes with an inclination of0°～ 45° is developed. The design principle of the unit is:dividing the operating range(0°～ 45°)into four sections, acquiring the optimum data of four-bar linkage adapted for each section according to the principle of the optimization of four-bar linkage,combining the four groups of data obtained onto the design of a single pumping unit to provide the unit with four adequate woading coitions.By adjusting the wolding position of the unit, it can operate on slant holes with any hole angle within 0°～ 45°under optimum conditions.
