METHOD OF WELL JET DEVICE OPERATING Russian patent published in 2017 - IPC F04F5/54 

FIELD: oil and gas industry.

SUBSTANCE: method of operating a jet apparatus is that the well with the low-pressure gas pipe is lowered on the column assembly, comprising a housing jet apparatus, the packer, and the gas inlet conduit from the wellbore packer space. A hopper inlet conduit at the middle perforation interval or gas reservoir wells at the sole. The unpacking of packer is held. The ejector housing mounted insert provided with a nozzle mixing chamber and diffuser. After the entrance to the nozzle body communicates with the annulus of the well. Mixing entrance communicates with the packer space through the gas supply pipe. Yield of the diffuser in communication with the tubing string. At the wellhead buffer wellhead valves with low-pressure gas is connected through a flow meter to the buffer wellhead wells with high-pressure gas. Through the annulus column borehole tubing with low-pressure gas is supplied a high-pressure gas from wells with high-pressure gas to the nozzle jet apparatus, creating a depression on a layer below the jet device and is pumped out of packer space borehole low-pressure gas and liquid, if present in the well. Pumped low-pressure gas, with or without liquid it is fed by the conduit to the mixing chamber where it mixes with the high-pressure gasses, supplied by the nozzle. The mixture of gases is discharged into the diffuser and on the surface of the consumer.

EFFECT: ability to increase the production rate of wells with low gas pressure through the use of energy of the gas, which is extracted from wells with high-pressure gas.
