UNIT FOR SIMULTANEOUS SEPARATE OIL PRODUCTION BY WELL WITH LATERAL INCLINED SHAFT Russian patent published in 2019 - IPC E21B43/14 

Abstract RU 2702180 C1

FIELD: oil and gas industry.

SUBSTANCE: invention relates to oil production and can be used for simultaneous separate production of borehole fluid by well with lateral inclined shaft. Proposed plant comprises tubing string arranged in casing, flow regulating and fluid metering unit (FRMU) with adjustment electric drives, two-way submersible electric drive with upper and lower centrifugal pumps, connected by power cable to power supply point through wellhead cable entry, telemetry system unit connected by communication cable with FRMU and instrumentation on control panel of power point for transmission of measurement results by telemetry sensors to control panel and commands in reverse direction, face and support packers, latter is equipped with cross flow clutch (CFC) radial channels of which are interconnected with the upper formation through a lateral inclined shaft, having diameter smaller than the diameter of the well casing, penetrating productive oil-bearing formations, and longitudinal flow channels – with a lower formation through the tail of sampling fluid of the formation fluid, connected to the inner pipe in a lateral inclined-directed barrel, and a split pipe joint. Upper centrifugal pump has inlet module for intake of mixed fluid and comprises additional working sections for increasing oil pressure. Lateral inclined shaft is hermetically installed in casing well bore, for passage of which in wall of casing well bore an aperture is made, and internal pipe – with central channel CFC. Bottomhole packer is made hydraulically and installed in the side inclined-directed shaft between the oil-bearing formations. CFC top is connected with lower part of detachable pipe connection by two-channel branch pipe installed in support packer.

EFFECT: technical result consists in improvement of operating efficiency of recovered oil producing wells due to side inclined barrel and providing reliability of plant operation.
