PROCEDURE FOR PREPARING AND MEASUREMENT OF PRODUCTION OUTPUT OF OIL WELLS AND DEVICE FOR ITS IMPLEMENTATION (VERSIONS) Russian patent published in 2011 - IPC E21B47/10 

FIELD: gas-and-oil producing industry.

SUBSTANCE: procedures for preparing and measurement of output of oil wells consists in multi-stage separation of mixture, in hydro-static weighing column of specified height of oil and water, alternately and separately chosen from their settled layers. Average values of pressure and temperature of a gas phase for a period of a liquid phase replacement are measured and calculated; also, there is measured volume consumption of liquid phase. The device consists of a gas separator, of a three-product hydro-cyclone, of a separator with stabilising grids, of oil-water and gas-liquid switches, of plungers, of bypass valves of discrete action, of level, pressure and temperature detectors and of a micro-processor.

EFFECT: upgraded accuracy and quality of measuring output of oil wells by separate components of their production.
