Abstract

The invention discloses a crude oil dehydration method and a crude oil dehydrator. Spherical impact waves are generated through high-voltage discharge in a water bag, and the impact waves penetrate through the water bag to act on crude oil, so that an oil film and a water film are broken, and dehydration is realized. According to the crude oil dehydration method provided by the invention, the mechanical wave effect is directly used in the water-containing crude oil, the dehydration effect is good, and no other side effects exist due to a pure physical method. According to the crude oil dehydrator provided by the invention, shock waves are generated through high-voltage discharge of the shock wave generator, the energy conversion efficiency is very high, the shock waves act on crude oil, and the oil film and the water film are broken, so that crude oil dehydration is achieved, the dehydration effect is good, the structure is simple, and the implementation is convenient.

Description

technical field [0001] The invention belongs to the technical field of crude oil dehydration, and relates to a crude oil dehydration method and a crude oil dehydrator. Background technique [0002] Water-containing crude oil is mostly a "water-in-oil" (W / O) emulsion, that is, water is wrapped inside the oil to form a "water pool", and its particle diameter ranges from 10 to 12nm. Dehydration of crude oil is an important link in the process of crude oil processing. At present, demulsifiers, heating and electro-chemical dehydration methods are generally used in various oil fields. As domestic oil fields generally enter the stage of high water-cut production, the comprehensive water cut of most oil fields is as high as 90%. The tertiary oil recovery technology uses a large amount of oil displacement agent, which makes the composition of the produced fluid and the state of oil-water emulsification extremely complicated. The viscosity of the emulsion is high and the particles ar...
