Abstract

The invention relates to the mechanical field, discloses a three-phase separator for foamed crude oil and aims to solve the technical problem that the three-phase separation effect is poor for foamed crude oil in the prior art. The separator comprises a tank, a first support, a second support, five sand collecting hoppers, a separation plate, an oil outlet pipe, a water outlet pipe, a first mist catcher, a second mist catcher, a connecting pipe, an oil-gas-water inlet pipe, a liquid reducing pipe, a liquid distributing pipe, two sieve plate type defoaming structures, a folded plate type mist catcher and a finned heat exchange defoaming device, wherein the separation plate divides the tank into a first tank space and a second tank space, and the inside of the second tank space is divided into an oil chamber and a water chamber; the liquid reducing pipe comprises a first pipe body, a second pipe body arranged at the bottom of the first pipe body as well as a third pipe body arranged at the bottom of the second pipe body; the finned heat exchange defoaming device penetrates through the two sieve plate type defoaming structures. The technical effects of increasing the oil-gas separation degree and the crude oil dehydration efficiency are realized.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a foamy crude oil three-phase separator. Background technique [0002] In the process of oil field production, the dehydration of conventional crude oil usually adopts the method of gravity sedimentation for three-phase separation of oil, gas and water. Substances and components, they can be adsorbed on the surface of oil-water or gas-liquid, and have a stabilizing effect on liquid droplets or bubbles, resulting in the emulsification and foaming of crude oil. During the dehydration process of crude oil, the dissolved bubbles precipitated from crude oil rise to After the crude oil liquid level, a stable foam layer is formed on the crude oil liquid level, causing a false liquid level in the separator, making it difficult to control the liquid level of the separator, resulting in incomplete oil-water separation, affecting the separation efficiency, and the separated crude oil contains water ...
