PROCEDURE FOR SIMULTANEOUS OPERATION OF SEVERAL OBJECTS IN PRODUCER AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC E21B43/14 

FIELD: gas and oil production.

SUBSTANCE: procedure consists in lowering production string equipped with devices for fluid lifting. Also, energy of flow of full fluid yield from a high pressure reservoir is used both for its proper lifting along the production string and for lifting fluid of low pressure reservoir through the production string at a higher level by means of a jet unit. A gas-lift procedure is added to flowing well procedure for lifting mixture of fluid to facilitate fluid mixture lifting from both developed reservoirs to a wellhead with required reserve of pressure of its full flow. A combined lift installation including at least two units of well fluid lifting is disclosed for implementation of the procedure. The jet unit installed in the production string between the packers is used at the first stage as a mixing unit and as a lifting unit of mixture of fluids of two developed reservoirs. Also, a cavity of w working nozzle of the jet unit is hydraulically communicated with a bottomhole zone of a lower high pressure reservoir, while a cavity of its receiving chamber is hydraulically tied with a bottomhole zone of an upper low pressure reservoir.

EFFECT: raised efficiency of process of simultaneous development of several reservoirs with one producer.
