| Abstract: | A new kind of oil production technology using sucker rod pump with a hydraulic feedback type unit at the bottom of the hollow sucker rod string is introduced. The new technology makes the sucker rod string downwards easily by applying a downward hydraulic force at the bottom of the hollow sucker rod string, which effectively solves the problem of large drag force on the downstroke in the present technology of this kind. Formulas for calculating maximum and minimum polished rod loads of the conventional technology and the hydraulic feedback type hollow sucker rod pumping technology are established. The differences between the two maximum or minimum polished loads are obtained. A calculation example is given, which further illustrates the advantages of the hydraulic feedback type hollow sucker rod pumping technology. |
