METHOD AND APPARATUS FOR DIGITAL METERING OF OIL WELL UNDER GAS-AFFECTED WORKING CONDITIONS

WIPO Patent Application WO/2024/001070

A1

A method and apparatus for digital metering of an oil well under gas-affected working conditions. The method comprises: determining a molar amount of a free gas in an oil pump corresponding to each pumping indicator diagram; determining a liquid production amount of a rod pump well corresponding to each pumping indicator diagram, according to the molar amount of the free gas in the oil pump corresponding to each pumping indicator diagram, and a pre-established rod pump well liquid production amount model, the rod pump well liquid production amount model being a rod pump well liquid production amount model established in advance, taking into account the impact of gas on the liquid production amount; and accumulating wellhead liquid production amounts corresponding to each pumping indicator diagram, to obtain a cumulative wellhead liquid production amount of the rod pump well.
