An oil-water separation apparatus has a housing that contains at least one longitudinal plate member arranged in a longitudinal direction of the housing () and inclined relative to a horizontal direction. The longitudinal plate member forms at least one fluid channel in an inner chamber of the housing. A first guiding hole is provided on the longitudinal plate member or between the longitudinal plate member and an inner wall of the housing, and is in communication with the fluid channel. A second guiding hole is provided on the longitudinal plate member or between the longitudinal plate member and the inner wall of the housing, and is in communication with the fluid channel and is placed lower than the first guiding hole is positioned. A collection pipe is arranged at a longitudinal downstream end of the housing, and is in communication with the inner chamber of the housing.

Oil-water separation device

Disclosed herewith a separation device for performing phase separation on a three-phase liquid. The device includes: a housing; at least one pair of longitudinal baffle plates; a flow channel formed between every pair of longitudinal baffle plates; and collection chambers formed between adjacent pairs of longitudinal baffle plates. Each collection chamber is provided with a transverse baffle plate to separate the collection chamber into a first phase and a second phase collection cells. Each flow channel is provided with multiple lateral baffle plates to separate the flow channel into multiple sub-channels. In the areas of each longitudinal baffle plate where the first phase and second phase collection cells are located respectively, said longitudinal baffle plate is provided with a first and a second phase guiding holes in communication with the first phase and the second collection cells respectively.

Separation device

A separator for an oil well produced fluid comprises a housing and a tube group arranged within the housing. The tube group includes a plurality of horizontal pipes in a layered arrangement along a vertical direction, and a plurality of vertical pipes which allows adjacent layers of the horizontal pipes to be in fluid communication with each other. The plurality of horizontal pipes shares an inlet pipe in communication with the outside of the housing, and each of the horizontal pipes has a respective outlet. The separator is configured in such a manner that the horizontal pipes in an upper layer, a middle layer, and a lower layer are respectively used as oil pipes, water pipes, and sediment pipes.
