SYSTEM FOR COLLECTING AND TRANSPORTING OIL WELL PRODUCTS Russian patent published in 2021 - IPC F17D1/00 

FIELD: oil and gas industry.

SUBSTANCE: invention relates to the oil and gas industry, namely to field equipment for collecting and transporting oil well products. The system includes a collection pipeline running from the production wells through group metering units, a pressure pipeline to the oil treatment unit with a separation unit through a booster pumping station, an ejector placed between the collection pipeline connected to the low-pressure chamber of the ejector and the pressure pipeline connected to the outlet of the ejector. The inlet of the ejector is equipped with a pressure line for water supply, which is connected to the reservoir pressure maintenance system by means of a comb for sampling part of the water going to the injection wells. To maintain the operation of the ejector within the maximum efficiency, the collection pipeline can be additionally equipped with a pressure sensor at the inlet to the ejector, equipped with a bypass pipeline with an adjustable gate valve, controlled by a control unit depending on the data from the pressure sensor. To control the water content of the pumped products before and after the ejector, the collection and pressure pipelines can be additionally equipped with appropriate samplers.

EFFECT: proposed system is simple and reliable and allows it to be operated in remote fields by using water partially taken from the reservoir pressure maintenance system for pumping through the ejector.
