Water-oil separation device capable of adapting to different water-oil ratios in oil exploitation

Abstract

A disclosed water-oil separation device capable of adapting to different water-oil ratios in oil exploitation comprises a working box body, a mixing cavity is formed in the working box body, a water storage cavity is formed in the working box body, and drainage holes are formed in the inner wall of the lower side of the mixing cavity and the inner wall of the upper side of the water storage cavityin a communicating mode. According to the invention, water and oil are layered in the mixing cavity by utilizing different densities of oil and water in the water-oil mixed liquid, redundant water isdischarged by utilizing a fixed volume, the oil suction device is triggered to collect oil floating on the surface of water after the oil in the mixing cavity reaches a certain content, and in the process, the viscosity difference between the oil and the water is utilized to sense the content ratio of water to oil in real time, and when the oil in the mixing cavity reaches a certain content, thedevice monitors the content of the oil in real time in order to avoid mistaken discharge of the oil and increase the oil absorption rate of the oil absorption device, so that water-oil separation canbe effectively performed on water-oil mixed solutions with different water-oil mixing ratios, and the stability is higher.

Description

technical field [0001] The invention relates to the field of petroleum exploitation, in particular to a water-oil separation device capable of adapting to different water-oil ratios in petroleum exploitation. Background technique [0002] The role of petroleum in the national economy Petroleum is an important energy source. Compared with coal, it has the advantages of high energy density, convenient transportation and storage, and less pollution to the atmosphere after combustion. [0003] When oil is extracted, the oil produced is often mixed with groundwater, and when the oil well stops blowing, in order to enable the oil well to continue to produce oil, water is injected into the oil layer through the water injection well to replenish energy and maintain the pressure of the oil layer. For water-oil separation, traditional water-oil separation devices have unstable separation effects on water-oil mixtures with different water contents, especially when the water-oil content...

Problems solved by technology

[0003] When oil is extracted, the oil produced is often mixed with groundwater, and when the oil well stops blowing, in order to enable the oil well to continue to produce oil, water is injected into the oil layer through the water injection well to replenish energy and maintain the pressure of the oil layer. For water-oil separation, traditional water-oil separation devices have unstable separation effects on water-oil mixtures with different water contents, especially when the water-oil content ratio is extremely extreme, it is easy to cause the separated oil to be mixed with water or the oil to be mis-discharged
