| 摘 要： | 针对聚合物驱抽油机井普遍存在的油管偏磨、抽油杆断脱的问题 ,提出了可行的解决方案 :在抽油泵上部加装缓冲装置减少或消除惯性载荷 ,改善抽油杆柱受力状态 ;在抽油泵下部加装补偿装置对泵进行灌注 ,提高泵效。两种装置的工作原理是 :在橡胶筒、壳体与上、下端盖组成的密封腔内充有氮气 ,靠气体的可压缩性作为能量转换元件 ;在井下工作时 ,当中心管压力增大时 ,吸入液体 ;而压力降低时 ,排出液体 ,从而使流体流动趋于均匀 ,改善杆柱的承载状况。给出的计算公式可用于装置的工作参数计算和结构设计计算

| Abstract: | In the light of eccentric wear of tubing and breaking-off of sucker rod, a feasible solution is put forward: fixing damping devices on the upper part of the subsurface pump to eliminate inertial load and improve the force condition of sucker rod; installing compensating devices on the lower part of the pump to improve pump efficiency. The structure and operating principle of the two devices are described. The equations for calculating the operating parameters of the devices are presented, and relevant lab tests are conducted. |
