Description

Technical Field

[0001] The present invention relates to the technical field of oil separate production, and more specifically, the present invention relates to an oil separate production device. Background Art

[0002] Petroleum refers to a mixture of gaseous, liquid and solid hydrocarbons with natural occurrence forms. Petroleum is further divided into crude oil, natural gas, natural gas liquids and natural tar, etc. However, conventionally, "petroleum" is still used as the definition of "crude oil". Petroleum is a viscous, dark brown liquid and is called the "blood of industry". There is petroleum storage in some areas of the upper crust. Its main components are mixtures of various alkanes, cycloalkanes and aromatic hydrocarbons. It is one of the main objects of geological exploration. Petroleum is an industrial term, relative to mineral resources. Generally speaking, the petroleum industry is a kind of mineral resource industry. During the petroleum exploration process, according to the exploration degree and the proven situation, the petroleum reserves are calculated and determined. Petroleum reserves are the results of geological exploration and are a kind of original mineral resource quantity to be developed. Crude oil is the petroleum extracted from rock formations, maintaining its original physical and chemical form. It is the primary product of the petroleum industry, realizing its use value and being the result of oilfield development. The crude oil production is a kind of mineral resource production that has been developed. The term "petroleum" is mostly used to describe the oil layer permeability, porosity and reservoir grade. Petroleum is mainly used as fuel and gasoline, and is also the raw material for many chemical industrial products such as solutions, fertilizers, pesticides and plastics. Layered oil production means that in a production well with multiple oil layers, packers are used to separate the oil layers into several sections, and the method of packer setting or production allocation is adopted to reduce the interference between layers, so that the oil layers can fully play their due roles and reduce or eliminate the interference between layers.

[0003] During the separate production of petroleum in layers, limited by the site, the multi-layer petroleum is only transmitted through a single pipeline, which affects the transmission efficiency of the multi-layer petroleum. Summary of the Invention
