Abstract
1. Способ определения дебита скважины эксплуатируемой с применением штангового глубинного насоса, включающий способ добычи нефти в режиме поддержания заданного значения величины перепада давления на пласт, при периодической откачке жидкости из скважины способ определения дебита скважины путем измерения времени заполнения фиксированного объема жидкости и расчет суточного дебита через объемный расход жидкости в единицу времени, применяемый, например, в серийных замерных установках типа ″БИУС″ или ″СПУТНИК″, отличающийся тем, что определение величины фиксированного объема жидкости производят непосредственно в скважине, в интервале затрубного пространства, расположенном над продуктивным пластом, где нефть находится в неразгазированном состоянии, расчетным путем с использованием связи между заданным значением величины перепада давления на пласт, избыточным давлением на устье затрубного пространства скважины с забойным давлением, местоположением уровня нефти и водонефтераздела (для обводненной нефти), а дебит определяют по времени перемещения этого уровня (уровней) в затрубном пространстве, который зависит, в конкретной скважине, от интенсивности притока жидкости из пласта и определяется с учетом следующих соотношенийдля чистой нефтидля обводненной нефтипри этом фиксированный объем жидкости определяют после остановки процесса откачки жидкости в период восстановления заданного значения перепада избыточного давления на устье затрубного пространства скважины из следующих соотношенийа) для чистой нефтиб) для обводненной нефтиа отсчет времени восстановления величины заданного значения п1. A method for determining the flow rate of a well operated using a sucker rod pump, including a method of oil production in the mode of maintaining a given value of the pressure drop across the formation, with periodic pumping of fluid from the well, a method for determining the flow rate of a well by measuring the time it takes to fill a fixed volume of fluid and calculating the daily flow rate through the volumetric flow rate of liquid per unit time, used, for example, in serial metering units of the type “BIUS” or “SATELLITE ″, characterized in that determination of a fixed fluid volume value is carried out directly in the well, in the interval of the annulus located above the reservoir, where the oil is in a non-degassed state, by calculation using the relationship between the set value of the differential pressure across the reservoir, the overpressure at the mouth of the annulus of the well with the bottomhole pressure, location of the level of oil and water-oil separation (for waterlogged oil), and the flow rate is determined by the time of movement of this level (level she) in the annulus, which depends, in a particular well, on the intensity of fluid flow from the reservoir and is determined taking into account the following relations for pure oil for irrigated oil, while a fixed volume of fluid is determined after the pumping process is stopped during recovery of the set differential pressure drop across the annulus the well’s space from the following relations:) for pure oil) for water-cut oil
