Oil-gas-water three-phase hypergravity separator

Abstract

The present invention relates to an oil-gas-water three-phase hypergravity separator, including a housing, one or more swirling hypergravity gas-liquid separators, one or more swirling hypergravity oil-water separators, a group of water return pipe, a group of oil return pipe, an oil-water interface controller and a solenoid valve. The housing is divided into a water-collection chamber, an oil-water chamber and an oil-collection chamber from bottom to top by a lower separation plate and an upper separation plate. The gas-liquid separator is inserted from the top of the housing, penetrated through the oil collection chamber and not communicated with the oil collection chamber. The inlet pipe and the exhaust port of the gas-liquid separator are located outside of the housing. The liquid discharge port of gas-liquid separator is communicated with the oil-water chamber. The oil-water separator is arranged in the oil-water chamber. The oil-water inlet of the oil-water separator is communicated with the oil-water chamber. The oil discharge outlet is communicated with the oil collection chamber. The water outlet is communicated with the water collection chamber. The oil collection chamber and the water collection chamber are communicated through the water return pipe and the oil return pipe. The oil-water interface controller and the solenoid valve control the water discharging. The oil-gas-water three-phase hypergravity separator solves the problem of large volume and large floor area of conventional three-phase separators.

Description

technical field [0001] The invention relates to the technical field of three-phase separation, in particular to a separator capable of separating oil, gas and water by three-phase supergravity. Background technique [0002] The oil-gas-water three-phase separator is a device that separates oil, gas and water in three phases. It is often used for the separation of crude oil, associated gas and water in oilfield production liquid. Patent 201110326022.3 is an oil-gas-water three-phase separator, including a pretreatment area, a packing area and a settling area. The upper part of the pretreatment area is the left-end mist catcher, the upper part of the settlement area is the right-end mist catcher, the left-end mist catcher and the right-end mist catcher are connected through a connecting pipe, and there are rectifying plates and baffles in the pre-treatment area; There are two coalescing fillers; there are multiple folded plate mist catchers in the settlement area, and a parti...
