Abstract
An underground liquid-gas separator is composed of an upper connector, an outer pipe, a valve element, a valve cover, a gas collecting cap, a central pipe, helical blades, a locating frame and a lower connector. The upper connector and the lower connector are connected with two ends of the outer pipe to form the shell body of the underground liquid-gas separator. The valve element is arranged in the side hole of the gas collecting cap, and the valve cover blocks the valve element. The valve element, the valve cover and the gas collecting cap form a vent valve which is fixed on the lower portion of the upper connector inside the shell body, and the valve cover exactly faces the side hole of the outer pipe. The locating frame and a plurality of spiral blades are fixed on the central pipe to from a spiral core body, and the spiral core body is fixed on the lower portion of the gas collecting cap inside the shell body. The underground liquid-gas separator can remove the free gas in oil-gas mixing liquid, improves the fullness degree of an oil well pump and prevents occurrence of an airlock phenomenon of the oil well pump.
Description
Technical field
The utility model belongs to oil well underground liquid air separation, especially is arranged on the bottom of oil well pump, the oil-gas mixture of supplying with oil well pump is carried out liquid gas separate, and prevents a kind of underground liquid gas separating device of oil well pump gas lock.
Background technology
At present, be used for the device that underground liquid gas separates, structural shape is old, and liquid gas separating effect is general, is not suitable with the exploitation of high gas-liquid ratio oil well.
Summary of the invention
Old in order to solve existing underground liquid air separation structural shape, the problem that liquid gas separating effect is general, the utility model provides a kind of underground liquid gas separating device.This underground liquid gas separating device can carry out the degassed and processing of exhaust of boosting of eddy flow to oil-gas mixture, plays the removing bubble, improves the effect of oil well pump degree of filling.Thereby prevent the oil well pump gas lock, improve the pumping efficient of oil well pump.
The technical scheme that its technical problem that solves the utility model adopts is: connect to form the underground liquid gas separating device by top connection, outer tube, spool, valve bonnet, gas-collecting cap, central tube, helical blade, locating rack and lower contact.Top connection and lower contact connect to form respectively the housing of underground liquid gas separating device with the two ends of outer tube.Spool is arranged in the side opening of gas-collecting cap, and valve bonnet blocks spool.Spool, valve bonnet and gas-collecting cap form outlet valve, and outlet valve is fixed on the bottom of top connection in housing, the side opening of valve bonnet on the outer tube.Locating rack and a plurality of helical blade are fixed on and form spiral core on central tube, and spiral core is fixed on the bottom of gas-collecting cap in housing.
When the oil well pump feed liquor, due to the pressure in the liquid-gas separator housing lower than its outside pressure, exhaust valve closure, oil-gas mixture can not enter in liquid-gas separator from outlet valve.Oil-gas mixture can only enter the underground liquid gas separating device from lower contact, and up along the helical flow path rotation that forms between spiral core and outer tube.Under the effect of centrifugal force, the liquid in oil-gas mixture is pooled to the deep side of helical flow path, and by the annular space between gas-collecting cap and outer tube, flows to top connection, supplies with the oil well pump feed liquor.Bubble in oil-gas mixture is assembled near central tube by the liquid extruding in helical flow path, and is entered in central tube from the side opening of central tube, under the effect of buoyancy and suction, upwards is pooled in gas-collecting cap.When oil well pump stopped feed liquor, the liquid in helical flow path stopped flowing, and the inertia of liquid causes that underground liquid gas separating device internal pressure rises, and the gas in gas-collecting cap is released outlet valve, is discharged in sleeve pipe.
The beneficial effects of the utility model are, can remove the free gas in oil-gas mixture, avoid oil well pump generation gas lock, thereby improve the degree of filling of oil well pump.
