Decrease of service life of pumping rods was determined as the viscosity of extracted fluid is growing. Analysis of repairs of Cavity Pumping Units was performed. Means with a proven efficiency for catching the suspended solids in extracted fluid – a tail pipe, a slurry trap and a gas-sand anchor have been developed. Fluids with various viscosities were obtained for determining the sedimentation rate of solids.
