The paper deals with the aspects of delivery rate increase of sucker-rod pumps in the long-developed fields. By the system analysis of the actual field data and corresponding calculations, the technical parameters of pumping, most influencing pump delivery rate have been specified, and their influence numerically estimated as well. For this purpose, the dependences of pump delivery on the flow rate of pumped fluid, as well as the watercut values of the products have been reviewed. The results of con¬ducted researches revealed the possibilities of more efficient use of well stock and production increase as a whole in considered field via increase delivery rate of pumps. Simplicity, clarity and reliability of results of described ap¬proach suggest its use in solving similar problems without involv¬ing additional field measures
