Problems solved by technology

[0002] With the continuous development of old oilfields, most old oilfields have entered the stage of high water-cut development, and the water content of oil wells has been increasing, and the water content of some oil wells has reached more than 95%, which has brought huge pressure to the established gathering and transportation systems and equipment. and cause serious energy consumption
In view of the insufficient processing capacity of the established oil and gas gathering and transportation systems in old oilfields, the high energy consumption of high water-cut crude oil transportation and treatment, explore miniaturized, intelligent, and refined oil, gas and water centralized purification treatment skids, and realize high-water-cut production fluids in well sites or On-site water division, on-site treatment at the metering station, on-site export of crude oil, and on-site reinjection of produced water are the keys to solving the above problems

Embodiment 1

[0051] An integrated device for oil, gas and water treatment with double-layer cavity full gravity balance, comprising an upper tank 1 and a lower tank 2; the upper tank 1 is located above the lower tank 2.

[0052] The upper tank 1 is provided with a blocking weir plate 3; the blocking weir plate 3 is provided with a separation weir plate 4; a liquid inlet chamber 7 is formed between the front end of the upper layer tank 1 and the blocking weir plate 3; A diversion channel 8 is formed between the weir plate 3 , the separation weir plate 4 and the inner wall of the upper tank 1 ; an overflow weir plate 5 and an overflow prevention plate 6 are sequentially arranged in the diversion channel 8 .

[0053] An oil-water mixing chamber 9 is formed between the guide channel 8 and the overflow weir plate 5 .

[0054] An emulsified oil cavity 10 is formed between the overflow weir plate 5 and the overflow prevention plate 6 .

[0055] A water collection chamber 11 is formed between the...

Embodiment 2

[0086] The specific difference between embodiment 2 and embodiment 1 is:

[0087] The upper end of the blocking weir plate 3 and the separation weir plate 4 is sealed and connected with the inner wall of the upper end of the upper tank 1; a cyclone separator 33 and a gas phase outlet 32 ​​are arranged above the oil-water mixing chamber 9; the cyclone separation The inlet of the device 33 communicates with the gas phase outlet 32 ​​, and the outlet of the cyclone separator 33 communicates with the oil-water mixing chamber 9 .

[0088] Through this design, the flow channel of the gas phase passes through the diversion channel 8 and then enters the cyclone separator 33 , preventing the liquid contained in the gas from dripping into the emulsified oil chamber 10 and the water collection chamber 11 .

[0089] Simultaneously, the internal circulation heating originally adopted in the settling clean oil chamber 19 and the electric dehydration chamber 20 is changed to external circula...

Abstract

The invention discloses a double-layer cavity full-gravity balance oil-gas-water treatment integrated device, and relates to the field of oil-gas-water treatment equipment. The device comprises an inclined pipe, an upper-layer tank and a lower-layer tank. The upper-layer tank comprises an oil-water mixing cavity, an emulsified oil cavity and a water collecting cavity; the lower-layer tank comprises a settling water purification cavity, a settling oil purification cavity and an electric dehydration cavity; the upper-layer tank is located above the lower-layer tank, the inclined pipe is locatedabove the upper-layer tank, and full-gravity balance oil-gas-water treatment is achieved by reasonably arranging the communicating flowing relation of all cavities between the upper-layer tank and thelower-layer tank. Compared with the prior art, the system has the beneficial effects that the system has the characteristics of low energy consumption, miniaturization, intelligence and refinement, purified crude oil can be directly discharged from high-water-content oil by one sledge, seven independent processes such as water pre-separation, heating, lifting, large-tank sedimentation, dosing andbackwashing in an existing combined station are replaced, the station process is greatly shortened, the energy consumption of a gathering and transportation system is reduced, and the cost is reduced. A strong support is provided for realizing a short-process mode of an old oil field.
