Field experience justifies that after the pump stops, the inflow of incompressible liquid from formation into the well lasts and the fluid level in the annular space increases. When skin-zone occurs, the liquid level in the pumping well increases slowly and durably. The paper offers a methodology of reviewing the impact of skin-factor on the operation of deep-well pump for incompressible fluids and the way of specifying the recovery time in operating pumping wells considering the skin-factor.
