INSTALLATION FOR PRODUCTION LIFTING FROM TWO-MOUTH WELL Russian patent published in 2009 - IPC E21B43/00 

FIELD: oil and gas industry.

SUBSTANCE: invention elates to gas-and-oil producing industry and is provided, particularly for extraction of high-viscous oils and bitumen. Installation for production lifting from two-mouth well, it is outfitted by perforated in area of productive stratum by production string, includes power unit with ability of reversing movement, force tractions with spool members, located in well, and hermetic sealing devices of mouth, outfitted by blowing lines. Spool members are implemented with ability of immediate interaction with production string, and power unit is implemented in the form of two located nearby each mouth of traction devices with ability of its operation with regulated motion synchronously opposite in phase by means of control assembly. Hermetic sealing devices of mouth are implemented with ability of intensification of wringing out of force traction at its lifting from well and reduction of tightening effort at motion of tractions into well.

EFFECT: simplification and reduction in price of the device, reduction of its steel intensity, productivity improvement, ability of production selection from the most effective section of well, increasing of operation resource.
