      <abstract xml:lang="ru">
        <p>Известно, что в настоящее время существует научный резерв, который позволяет, при наличии интереса у нефтяников и производителей нефтегазового оборудования, разрабаты­вать насосы, размещаемые в скважине и не подверженные вредному влиянию свободного газа, а также наземные подъемные установки для перекачки многофазных сред, вызова при­тока газожидкостной смеси в процессе заканчивания скважины и перекачивания водонефте- газовых смесей в системах сбора нефти.</p>

      <abstract xml:lang="en">
        <p>It is known that at present there is a scientific reserve, which allows, if oilmen and oil and gas equipment manufacturers are interested, to develop pumps placed in the well and not subject to harmful influence of free gas, as well as surface lifting units for multiphase media pumping, causing inflow of gas-liquid mixture during well completion and pumping water-oil-gas mixtures in oil gathering systems.</p>
