FIELD: petroleum extraction industry. SUBSTANCE: condition for pump placement without curve in suspension interval in curved well portions is determined from relationship LA<=[LA], where LA is length of pump in meters, and [LA] is possible length of pump placed inside curved portion of well in meters. Possible length of pump is determined from relationships in inventive formula on conditions concerning heightening and lowering of well inclination angle. EFFECT: increased productiveness of pump before service failure and minimized pump falling distance in the well due to placement in suspension interval without curve. 2 dwg |
