Claims (1)
где lk - расстояние между перепускными клапанами, м;
(Рм - Рв) - избыточное давление в межтрубном пространстве при установившемся режиме работы скважины, МПа;
Рм, Рв - давления соответственно в межтрубном пространстве и на выкидной линии скважины, МПа;
ρсм - плотность газожидкостной смеси в межтрубном пространстве, м/м3;
g - ускорение свободного падения, м/с2 (g = 9,81 м/с2).An energy-saving sucker-rod suction pump installation comprising a column of lifting pipes with a bypass valve, a sucker-rod column, a pump with a plunger and a shank at its inlet, located in the gas separator casing with gas outlet valves and a shank, characterized in that the shank at the pump intake is equipped with an open top cone and the bottom, on the outer forming surface of which annular grooves are made with sharp protrusions, while the volume of the annular space formed between the receiving part of the shank and with a glass selected equal to the volume of liquid for the pump supply cycle, the annular space is communicated with the pump through the openings on the shank, the total area of the flow cross-sections of which is equal to the flow cross-section of the annular space, and an overflow valve is additionally installed on the column of lifting pipes below the bypass valve, and the distance from the first valve is determined from the condition
where l k is the distance between the bypass valves, m;
(P m - P in ) - overpressure in the annular space at a steady state well operation, MPa;
P m , P in - pressure, respectively, in the annulus and on the flow line of the well, MPa;
ρ cm is the density of the gas-liquid mixture in the annulus, m / m 3 ;
g is the acceleration of gravity, m / s 2 (g = 9.81 m / s 2 ).
