RESEARCH OF MATHEMATICAL MODELS FOR SIMULATING DOWNHOLE FAILURE CONDITIONS OF PUMPING WELL

    Graphical Abstract
    • Abstract
  • Based on the dynamometer card, this paper studies the kinematic characteristics of failure conditions of pumping well, such as gas lock, liquid pounding, pump collision, fracture or dropout of rod and tube, presents relevant mathematical models, and the solutions of which are satisfactory, that is, the simulation results can basically reflects the characteristics of pumping well under various kinds of failure conditions. This paper has provided theoretical basis for further study in this aspect.
