Description

Hydraulic high-pump-efficiency oil-gas mixed transportation supercharging device Technical Field The invention relates to the technical field of oil-gas mixing and conveying devices, in particular to a hydraulic high-pump-efficiency oil-gas mixing and conveying supercharging device. Background With the development of the oil field entering the middle and later stages, the oil well is increasingly far away from the joint station, the gathering and transportation radius is continuously increased, the return pressure of a far-end oil port is continuously increased, and the normal production of the oil field is seriously restricted. At present, the field mainly relies on wellhead oil pulling or pressurization technology to relieve the back pressure problem. According to the difference of gas content of the produced liquid of the oil well, the pressurizing process adopts a double-set equipment mode of 'gas-liquid separation before pressurizing and mixing respectively', or adopts a screw pump and other single equipment to pressurize. The method has the advantages that the method can adapt to the working condition of higher gas content, but has large equipment investment and complex flow, and the method has certain applicability when the gas content is low, but the contents of sewage, associated gas, carbon dioxide, sand grains and other impurities in the produced liquid are obviously increased along with the deterioration of the exploitation condition, and the traditional equipment such as a screw pump, a centrifugal pump and the like are easy to generate cavitation, wear and blockage, the reliability is reduced, and the maintenance frequency is increased. Under the background, the piston pump gradually becomes a concerned direction of oil-gas mixed transportation pressurization due to the strong medium adaptability and high-pressure transportation capability. The utility model patent with the publication number of CN220267922U discloses an oil-gas mixed transportation piston pump, wherein a liquid outlet is formed in the top of a valve body, a liquid inlet communicated with the liquid outlet is formed in the bottom of the valve body, a spring is stretched when a lower valve core, an upper valve core and a bolt move upwards, potential energy is applied to the spring, the spring releases the potential energy when reset, the upper valve core and the lower valve core move close to the valve body, a sealing gasket between the upper valve core and the lower valve core replaces the lower valve core to contact the liquid outlet, the sealing gasket is stressed to bend, a gap between the liquid outlet and the lower valve core is sealed, the contact between the lower valve core and the valve body can realize second sealing, the problems of loose sealing and liquid leakage cannot be generated when the sealing gasket exceeds the use limit, and a limiting part can limit the position of the bolt, so that the sealing gasket cannot rotate and relax due to up-down reciprocating movement. The technical scheme realizes the purpose of double sealing by means of the combined action of the upper valve core, the lower valve core, the sealing gasket between the upper valve core and the lower valve core and the liquid outlet, so that the problem that the sealing gasket cannot be completely sealed when the use limit is exceeded is solved, but the upper valve core has obvious defects in the practical use process that the upper valve core is easy to be blocked by sand grains, scaling or other impurities or deformed due to corrosion and fatigue of media in long-time operation, so that the upper valve core cannot be normally closed, once the problem occurs, internal reflux and pump efficiency suddenly drop, and the production continuity is influenced and the maintenance cost is increased due to the fact that the sealing gasket is required to be disassembled and overhauled in severe cases.
