Abstract
As it is known, currently, the fields at the last stage of development are operated predominantly with sucker-rod pumps. Their operation is usually carried out in quite complicated technological and hydrodynamic conditions dramatically affecting the operation efficiency. Based on the actual field data, the paper studies the possible impact of the depth of sucker-rod pump running on the delivery rate, which is one of the indexes of operation of the whole sucker-rod pump unit. The values of delivery rates by oil and water have been calculated and their functional dependencies on the depth of sucker-rod pumps running developed as well. The results justified the increase of delivery rate by oil and its decrease by water in reviewed value diapasons. Mathematical models of developed dependencies have been obtained as well. As a result of conducted studies, the practicability of the increase of pump setting depth in operation conditions of reviewed field is justified.
