FIELD: oil production, particularly active estimation of oil and gas-condensate wall production rate in pressure-sealed gathering facilities.
SUBSTANCE: method involves filling measuring vessel having calibrated volume with well product for time period defined with taking into consideration of maximal device efficiency with gas pipeline communicated with manifold and with closed fluid discharge pipeline; stopping well product supply into measuring vessel at the expiration of the time period; measuring fluid column height, hydrostatic pressure and temperature; calculating fluid, oil, water output; continuing well product delivery into measuring vessel with closed gas pipeline and liquid pipeline communicated with manifold; determining measuring vessel unloading rate and excessive pressure; calculating gas output; determining water content in well product contained in measuring vessel by setting thereof up to foam settling and absence of gas bubbles only in 2% of total measurement amount; performing remainder measurements for output determination after receiving of stable fluid-gas interface surface height readings or measurements are performed without setting operation if possible.
EFFECT: decreased measurement cycle duration along with increased foam-generation and well output.
