针对现有斜井抽油杆柱扶正器间距设计方法存在间距过小 ,造成抽油杆上行摩擦阻力大 ,下行出现活塞效应的问题 ,提出了考虑井斜角、方位角、全角、井斜变化率、方位变化率及井下摩阻 6个因素模糊综合评判法。该方法将评判因素参数中摩擦阻力作为主要因素 ,权值取最大。给出计算摩擦阻力的公式 ,并对胜利油田桩西采油厂桩 10 6 - 2 0 -x15斜井进行评判后确定了 12个扶正器的扶正位置。 Aiming at the problem that the design method of centralizer centralizer spacing of existing skew-well sucker rod column is too small, the frictional resistance of the sucker rod is large and the piston effect occurs in the downward direction. Aiming at the problem that the inclination angle, azimuth angle, Rate of change of orientation and downhole friction 6 factors fuzzy comprehensive evaluation method. The method takes the frictional resistance as the main factor in the parameter of the judgment factor, and the weight takes the largest value. The formulas for calculating the frictional resistance are given, and the righting positions of 12 centralizers are determined after the pile of 10 6 - 2 0 -x15 inclined shafts in the piled West Petroleum Production Plant of Shengli Oilfield is judged.
