Изобретение относится к добыче нефти и может быть использовано для эксплуатации малодебитных скважин, в частности погружными центробежными электронасосами с частотно-регулируемым приводом. Способ основан на регулировании скорости притока жидкости из пласта в скважину путем периодического повторения циклов, каждый из которых состоит из последовательно осуществляемых процессов запуска насоса при увеличивающейся частоте питающего напряжения, подачи жидкости насосом в колонну подъемных труб при повышенной по сравнению с номинальным значением частоте и уменьшения до нуля подачи насоса путем снижения частоты питающего напряжения по достижении заданной величины давления в колонне подъемных труб с последующим отключением насоса и сливом жидкости из колонны подъемных труб через насос в скважину. При прекращении подачи насоса в цикле предотвращают слив жидкости из колонны подъемных труб через насос в скважину путем регулирования напора, развиваемого электронасосом при нулевой подаче изменением частоты питающего напряжения в соответствии с восстановлением давления в скважине и в колонне подъемных труб, происходящем под действием притока жидкости из пласта, и возобновляют подачу насоса переводом его на повышенную частоту после заданного восстановления с последующей откачкой жидкости до заданной величины давления в скважине. В процессе восстановления поддерживают наибольшую частоту питающего напряжения, при которой насос еще не возобновляет подачу жидкости.The invention relates to oil production and can be used for the operation of low-production wells, in particular submersible centrifugal electric pumps with a variable frequency drive. The method is based on controlling the rate of fluid flow from the formation into the well by periodically repeating cycles, each of which consists of sequentially running processes of starting the pump with increasing frequency of the supply voltage, pumping liquid into the column of lifting pipes at a higher frequency compared to the nominal value and decreasing to zero of the pump supply by reducing the frequency of the supply voltage after reaching a predetermined pressure value in the column of lifting pipes with subsequent shutdown of pump and draining the liquid from the column of lifting pipes through the pump into the well. When the pump is stopped in the cycle, liquid is drained from the column of lifting pipes through the pump into the well by regulating the pressure developed by the electric pump at zero flow by changing the frequency of the supply voltage in accordance with the restoration of pressure in the well and in the column of lifting pipes that occurs under the influence of fluid inflow from the reservoir , and resume the pump by transferring it to an increased frequency after a given recovery, followed by pumping the liquid to a predetermined pressure value in the well. During the recovery process, the highest frequency of the supply voltage is maintained, at which the pump still does not resume the flow of fluid.
