METHOD OF OIL AND GAS TRANSPORTATION Russian patent published in 2023 - IPC F17D1/14 E21B43/34 

FIELD: gas transportation.

SUBSTANCE: invention relates to the technique and technology of collecting and transporting gas-liquid mixtures and can be used in the collection and transport of well products of oil and oil and gas condensate fields, in particular, in the field collection of gas-water-oil mixtures with a high gas content. The method of transporting oil and gas consists in supplying a gas-liquid mixture from production wells to a pipe separator, separating the gas-liquid mixture into gas and liquid in it, and transporting gas and liquid flows through separate pipelines. After the pipe separator, the gas flow is directed to the track liquid collector with a storage tank connected to the liquid pipeline. The section of the gas pipeline connecting the track liquid collector with the pipe separator is made with a length corresponding to the minimum formation length of the first liquid plug. The section of the liquid pipeline located between the pipe separator and the line fluid collector is installed parallel to the section of the gas pipeline connecting the line liquid collector with the pipe separator. To ensure the flow of liquid from the storage tank of the track collector into the liquid pipeline, pressure is reduced on the section of the liquid pipeline located between the pipe separator and the track collector by reducing the diameter of this segment relative to the diameter of the liquid pipeline or by installing a reducing valve on this section.

EFFECT: invention helps to prevent the formation of high-speed liquid plugs in the gas pipeline by improving the quality of liquid separation from the transported gas stream.
