METHOD FOR PRODUCTION AND TRANSPORTATION OF WELL PRODUCTS AND GAS Russian patent published in 2022 - IPC E21B43/12 E21B33/03 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas industry, and in particular to the regulated selection of well products and annular gas. To implement the method for production and transportation of well products and gas, well products are pumped through a pressure pipeline through an ejector device. The low-pressure intake chamber of the ejector pumps gas from the annulus of the wells through the wellhead fittings and the check valve. The pressure line equipped with an ejector device is connected to the annulus of all wells connected to the pressure pipeline through a common check shut-off valve. An adjustable safety valve is installed between the wellhead fittings and the check valve of each well, which turns off gas extraction when the gas pressure in the corresponding well drops below the allowable pressure, which is previously determined during the study of this well to prevent reaching critical pressure.

EFFECT: ensuring the possibility of controlled gas extraction by one ejector device from the annulus of several wells, the products of which are pumped through a pressure pipeline, excluding the decrease in gas pressure in the corresponding wells to critical pressure.
