Abstract
1. Адаптивный способ определения остаточного (свободного) газосодержания на групповых замерных установках, заключающийся в поочередном, по заданной программе, измерении массы и плотности, предварительно отсепарированной от газа жидкости, массы газа и объемной доли воды и нефти каждой скважины, прошедших соответственно через массовые счетчики жидкости, газа и поточный влагомер за фиксированный интервал времени, с пересчетом в суточную производительность соответственно по массовому расходу сырой нефти (водонефтяной смеси), массовому расходу нефти и объемному расходу нефтяного газа, отличающийся тем, что вычисляется расчетное значение плотности сырой нефти по формуле: ! , ! где ρн и ρв - плотности, соответственно, нефти и воды, измеренные лабораторным путем по каждой скважине; ! W - средняя обводненность водонефтяной смеси, определенная по ряду измеренных поточным влагомером мгновенных значений Wi, ! на основании ряда мгновенных значений плотности сырой нефти по каждой подключенной для измерения нефтяной скважине определяется среднее значение плотности , при этом, если разность и изменяется на величину Δρ≥Δρабс (где Δ ρабс - абсолютная погрешность измерения плотномера), то остаточное газосодержание сырой нефти определяют по формуле: ! . ! 2. Адаптивный способ определения остаточного (свободного) газосодержания на групповых замерных установках по п.1, отличающийся тем, что численное значение Кг может быть использовано для корректировки массы нефти Мнг в нефтеводогазовой смеси и объема Vг остаточного свободного газа в смеси соответственно по формулам: ! ; ! .1. An adaptive method for determining the residual (free) gas content in group metering units, which consists in alternating, according to a given program, measurement of mass and density pre-separated from the gas fluid, the mass of gas and the volume fraction of water and oil of each well, passed through mass meters, respectively liquids, gas and flow hydrometer for a fixed period of time, with conversion to daily output, respectively, according to the mass flow rate of crude oil (oil-water mixture), mass course of oil and gas volumetric flow rate, characterized in that the calculated estimated density value of the crude oil by the formula: ! where ρн and ρв are the densities, respectively, of oil and water, measured by laboratory methods for each well; ! W is the average water-oil mixture water cut, determined from a number of instantaneous values Wi,! on the basis of a number of instantaneous values of the density of crude oil for each oil well connected for measurement, the average density value is determined, and if the difference changes by Δρ≥Δρabs (where Δ ρabs is the absolute error of the density meter), the residual gas content of crude oil is determined by formula:! . ! 2. The adaptive method for determining the residual (free) gas content in group metering facilities according to claim 1, characterized in that the numerical value of Kg can be used to adjust the mass of oil Mng in the oil-gas mixture and the volume Vg of residual free gas in the mixture, respectively, according to the formulas:! ; ! .
