Problems solved by technology

This traditional process can effectively remove most of the suspended water in crude oil, and the equipment is simple and easy to operate; however, the scale of the settling equipment is large, the settling process takes a long time, the energy consumption is high due to heating, and there are environmental problems due to the addition of a large amount of chemical agents
[0005] In addition, there are other new processes or devices, such as the use of three-phase separators or hydrocyclones for pre-dehydration, but the dehydration efficiency and adaptability are still not ideal; and when the incoming liquid pressure is low, energy needs to be added to increase the pressure In order to meet the dehydration requirements; while the traditional two-layer T-shaped pipe is mainly distributed along the longitudinal and vertical directions, the oil-water separation efficiency is not ideal

Embodiment 1

[0051] Such as Figure 1a with 1b Shown is a single set of pipeline oil-water separator, including a plurality of straight pipes for circulating the oil-water mixture to be separated, and a vertical corrugated plate 6 vertically installed in the straight pipes to realize rectification and coalescence.

[0052] One straight pipe is arranged on the horizontal plane, and five straight pipes are vertically stacked in the vertical plane. At the port of the oil-water separation straight pipe and at the port of the adjacent oil storage straight pipe 1 or water storage straight pipe 3, they are adjacent to each other up and down. The ports of the two straight pipes are communicated through the connecting main pipe 4 and the connecting auxiliary pipe 5, and at the inlet end of the connecting main pipe 4, there is a swirl plate 7 to realize the flow swirling.

[0053] In this embodiment, at least five straight pipes are vertically stacked. The vertical corrugated plate 6 in the straigh...

Embodiment 2

[0055] Such as Figure 2a with 2b As shown, there are multiple sets of pipeline oil-water separators, including multiple straight pipes for circulating the oil-water mixture to be separated, and vertical corrugated plates 6 vertically installed in the straight pipes to achieve rectification and coalescence.

[0056] Three straight pipes are arranged side by side on the horizontal plane, and at the same time, five straight pipes are stacked vertically on each straight pipe at the vertical height, at the outlet port of the oil-water separation main pipe 2 and at the adjacent upper and lower layers of oil or water storage straight pipes 3 Between the liquid inlet ports in the upper and lower layers, and between the inlet and outlet ports on the same side of the adjacent upper and lower layers of oil storage straight pipes 1 or water storage straight pipes 3 are communicated through the connecting main pipe 4 and the connecting auxiliary pipe 5. At the same time, at the entrance o...

Abstract

The invention provides an oil-water separation device and application. Oil-water separation pipelines are arranged in a three-dimensional space according to a extended-range time delay principle; through layer-by-layer gravity sedimentation, water and oil in crude oil production liquid or oil-containing sewage are separated, thereby achieving a good oil-water separation effect; whether for a pre-separation, coarse separation or fine separation process, the effect of almost no oil in discharged liquid discharged from a water outlet pipe at the bottom of a pipe body can be achieved; the discharged liquid can directly enter a gravity settling tank or other processes through branch pipelines for further separation; and the water contained in the oil discharged from an oil outlet in the top ofthe pipe body can be reduced to less than 20%.

Description

technical field [0001] The present invention relates to the field of oil-water separation equipment, in particular to an oil-water separation device that sets oil-water separation pipelines in three-dimensional space according to the principle of extended range and delay, and separates water and oil in crude oil production fluid or oily sewage through layer-by-layer gravity settlement. and applications. Background technique [0002] In the oil extraction industry, as most oilfield development enters the high water cut stage in the middle and late stages, the water cut of crude oil production fluid continues to increase. The water content in the produced fluid not only causes rapid equipment aging during the storage, transportation and refining process of crude oil, increases the operating load, and increases energy consumption, but also easily causes tower flushing, corrosion and blockage of pipelines, abnormal operation of atmospheric and vacuum distillation towers, and cat...
