An integrated device for oil, gas and water treatment with double-layer cavity and full gravity balance

Abstract

The invention discloses an integrated device for oil, gas and water treatment with full gravity balance in double-layer chambers, and relates to the field of oil, gas and water treatment equipment. Including inclined pipe, upper tank and lower tank. The upper tank includes an oil-water mixing chamber, an emulsified oil chamber and a water collection chamber; the lower tank includes a settling water purification chamber, a settling oil purification chamber and an electric dehydration chamber; the upper tank is located above the lower tank, and the inclined pipe is located above the upper tank. The connection and flow relationship of each cavity between the upper tank and the lower tank is laid out to realize the full gravity balance oil, gas and water treatment. Compared with the prior art, the present invention has the beneficial effects of low energy consumption, miniaturization, intelligence, and refinement, and can realize high-water-content oil directly outputting purified crude oil from a skid, instead of pre-dividing water, heating, Seven separate processes including lifting, large tank settlement, dosing, and backwashing greatly shorten the station process, reduce the energy consumption of the gathering and transportation system, and provide strong support for the old oilfield to realize the short process mode.

Description

technical field [0001] The invention relates to the field of oil, gas and water treatment equipment, in particular to an integrated device for oil, gas and water treatment with double-layer cavity full gravity balance. Background technique [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 bring 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-cu...

[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
