Description

(54) SILVER OUTLINE

The invention relates to the oil industry, namely to collecting oil, gas and water in an oil field. There is a method of joint transportation of oil and gas from a field, which separates the production of wells by about & oil and gas, followed by separation of water from oil fl. Neosg & t method is that the production of wells is transported at the expense of the energy of the reservoir or the depth of the installation, which imposes a limitation on the productivity of the well and reduces the repair period. A well-known volumetric pump is capable of pumping a transported medium with the help of a working fluid, which may also be a gas-fluid mixture 2. However, in the case of joint transportation of oil and gas by means of a known volumetric displacement pump, together with the oil and gas of the reservoir water is transported to the central collection point, from which: it must return to the field for injection into the reservoir. This increases pipeline corrosion. The closest technical inventions to the invention is the collection system in the form of a complex of facilities at the field, which includes wells, group installation meters, to a pumping station, where gas separation is provided, preliminary dehydration of oil to the oi water pumping into the tUiacTO support system 3 j. The disadvantage of the collection system with a booster pumping station is the presence of a separate pipeline for cracked gas. The purpose of the invention is to simplify the system by combining the transport of oil and gas through a single pressure pipe. This goal is achieved, Vto in the oil and gas collection system as
