Oil-gas mixed convey pumping set for oil field

Abstract

The invention provides an oil field gas mixing delivery pump units. It mainly includes mixing delivery pump, reduction motor, oil gas voltage stabilizing tank and out transmission mixing delivery tank; the tank body of the oil gas voltage stabilizing tank and the out transmission mixing delivery tank both are equipped with input and output mouth, and the input and output mouth of the oil gas voltage stabilizing tank is installed along the tangent direction of the tank body, its input mouth is higher than output mouth. The input mouth of the out transmission mixing delivery tank is lower than its output mouth. The input and output mouth of the mixing delivery pump is connected with output mouth of oil gas voltage stabilizing tank and the input mouth of out transmission mixing delivery tank through oil pipes. The transported polyphase media collected from each oil wells is vortex stabilized its pressure through oil gas voltage stabilizing tank, then enters mixing delivery pump, improves the sucking condition of gas mixing delivery pump, and the out transmission mixing delivery tank can prevent the excavating cavity and sucking cavity of mixing delivery pump generate air-resistance effectively, meets the requirement of polyphase media can be transported in any operating mode condition with different gas-liquid ratio. Thus, the invention improves the efficiency of oil gas mixing delivery and the safe performance, reduces pollution, and it has good economic and social benefits.

Description

Technical field [0001] The invention relates to an oil-gas mixed transportation equipment used in an oil field, in particular to an oil-gas mixed transportation pump unit. Background technique [0002] In the process of oil exploitation, oil and gas mixed transportation is a very important technology. It involves technical issues such as environmental protection, consumption reduction, resource conservation, and full recovery of oil and its associated resources. At present, the commonly used oil and gas transportation equipment is a mixed pump. First, the multiphase medium from each dispersed oil production well is introduced into the buffer tank or separator tank of the external booster station through the manifold. When the gas-liquid ratio is small (that is, the gas content When the gas-liquid ratio is relatively large (that is, the gas content is high), the mixed-transport pump cannot transport it, and it needs to go through the buffer tank to the atmosphere. Excessive...

Problems solved by technology

Moreover, due to the different geological conditions of each oilfield, the gas-liquid ratio is a variable, which also makes it more difficult to transport oil and gas, and the release of gas phase media into the atmosphere occurs from time to time.

Therefore, it is difficult to adapt to the change of gas-liquid ratio by simply using conventional conveying machinery-mixed pumps, and cannot fully recover natural gas, which not only wastes resources, pollutes the environment, but also reduces economic benefits
