On the basis of generalization and systematization of well ejection systems constructions, taking into consideration peculiarities of operation and experience of their practical application, has been worked out classification scheme of ejector pumps, which are used during oil-and-gas field development. Elements of suggested classification scheme have been considered by example of real constructions of ejection equipment. It has been established, that existing well ejector pumps constructions can be divided into three groups, which fulfill sucking, forcing, forcing and sucking washing of the well bottom. Efficiency of the main schemes of ejector pumps application while well drilling has been analyzed. It has been showed that maximum efficiency of the process occurs while using ejection systems of forcing and sucking type. Systematization of well ejector pumps constructions allows to widen considerably sphere of their application and to determine the ways of ejection technologies improvement.
