ANALYSIS OF TENDENCIES OF EJECTION OIL AND GAS TECHNOLOGIES DEVELOPMENT

Stages of development of ejector pumps, which are used while drilling, operation and repair of oil and gas wells have been analyzed. Linear dependence between admissible depth of ejector pump placement in a well and amount of pressure, created by surface power drive has been established. Possibility of increasing operational efficiency of well ejection systems by means of joint arrangement of ejector pump, electrical and centrifugal, piston, screw and gaslift units has been shown. On the basis of using the methods of mathematical statistics has been analyzed dynamics of increasing the period between well ejector pumps repairs. Distribution of ejection technologies by particular technological processes, which can be accomplished by means of using well ejector pumps, has been determined.
