Claims (3)

1. Способ подъема жидкости из скважин на поверхность, включающий спуск в скважину двойной колонны труб, установку плунжерного насоса на нижнем участке внутренней колонны и закачку в межколонное пространство рабочего агента для привода в движение плунжерного насоса, отличающийся тем, что в межколонное пространство закачивают газ под давлением, превышающем гидростатическое давление столба жидкости во внутренней колонне на величину:
Figure 00000001

где Р - давление газа в межколонном пространстве;
γc - средневзвешенная плотность смеси (нефть, газ, вода);
Н - глубина погружения плунжерного насоса;
S1 - площадь плунжера сверху;
S2 - площадь плунжера снизу;
ΔP1 - избыточное давление газа, затем газ с заданной периодичностью стравливают на величину давления
Figure 00000002

а начальную величину газового давления восстанавливают и поддерживают за счет подкачки от компрессора.1. A method of raising liquid from wells to the surface, including the descent of a double pipe string into the well, installing a plunger pump in the lower portion of the inner string and pumping a working agent into the annular space to drive the plunger pump, characterized in that gas is injected into the annulus pressure exceeding the hydrostatic pressure of the liquid column in the inner column by:
Figure 00000001

where P is the gas pressure in the annulus;
γ c - weighted average density of the mixture (oil, gas, water);
H is the immersion depth of the plunger pump;
S 1 - the area of the plunger on top;
S 2 - the area of the plunger from the bottom;
ΔP 1 - overpressure of the gas, then the gas with a predetermined frequency bleed by the pressure
Figure 00000002

and the initial value of the gas pressure is restored and maintained by pumping from the compressor. 2. Способ по п.1, отличающийся тем, что для регулирования числа качаний плунжерного насоса изменяют частоту стравливания газового давления в межколонном пространстве. 2. The method according to claim 1, characterized in that to control the number of swings of the plunger pump, the frequency of gas pressure bleeding in the annular space is changed. 3. Устройство для реализации способа по п.1, состоящее из плунжерной пары, установленной в трубе внутренней колонны, имеющей посадочное гнездо и помещенной с зазором в трубу наружной колонны, отличающееся тем, что гильза и плунжер выполнены в виде стаканов с отверстиями на дне нормально закрытыми шарами, а между седлом плунжера и седлом гильзы имеется зазор, образующий кольцевую полость, через отверстия в трубе соединенную с межколонным пространством, которое ниже изолировано от сообщения со скважиной. 3. The device for implementing the method according to claim 1, consisting of a plunger pair installed in the pipe of the inner column having a seat and placed with a gap in the pipe of the outer column, characterized in that the sleeve and plunger are made in the form of glasses with holes in the bottom normally closed balls, and between the seat of the plunger and the seat of the sleeve there is a gap forming an annular cavity through openings in the pipe connected to the annular space, which is below isolated from communication with the well.
