Thickened oil three-phase separator used for removing free water and combining thin oil

Abstract

The invention discloses a thickened oil three-phase separator which is used for removing free water and reducing viscosity by adding thin oil and is used in oil fields and mine fields. The thickened oil three-phase separator is composed of an outer shell, a separation cavity, a gas-liquid pre-separation barrel, a liquid distributor, an inlet, a gas communication pipe, a gas outlet, a gas distribution bag, separation filler, a thin oil adding distributor, a thin oil distribution mouth, a chemical agent distributor, a chemical agent distribution mouth, an oil spilling weir plate, a water outlet, an oil outlet, an oil cavity, a thickened oil and thin oil mixer, and the like. A thin crude oil distributor and a thin oil distributor are arranged in the separator, and then thin oil is enabled to permeate into a certain position inside the separation cavity, and then the viscosity of thickened oil is reduced after the free water is removed. The chemical agent distributor and the chemical agent distribution mouth are arranged in the separator, chemical agents are enabled to permeate into a certain position inside the separation cavity, and chemical demulsification is carried out on the thickened oil after the free water is removed. The thickened oil and thin oil mixer is arranged at the position of the oil cavity of the oil outlet of the separator, mixing degree of the thickened oil and the thin oil is increased with methods such as a mechanical vibration method, and the thickened oil is enabled to be discharged out of the separator smoothly.

Description

1. Technical field [0001] The invention relates to a device for removing free water and reducing the viscosity of mixed thin crude oil in heavy oil field, in particular to a heavy oil three-phase separator combining free water removal and mixed thin oil. 2. Background technology [0002] my country is rich in heavy oil resources, and heavy oil has become an important part of my country's oilfields to stabilize and increase production. However, there have always been problems of high energy consumption and high cost in heavy oil gathering and transportation, which restrict the development of heavy oil. Especially in recent years, with the development of ultra-heavy oil resources, oilfields are faced with the problems of high energy consumption, high temperature, and serious safety hazards in the processing of heavy oil; The difficulty is increasing. [0003] Many oilfields use water-mixing method to transport heavy oil, but in the process of processing, it is necessary to u...

AI Technical Summary

Problems solved by technology

However, if it is not mixed with dilute wells in the station, the free water will be removed first, and the heavy oil after removal of free water will have a high viscosity, which will cause difficulty in transportation in the station, affect production, and also affect the separation effect
