Problems solved by technology

The measurement of water cut is also related to flow measurement. Therefore, so far, there is no crude oil water cut measurement method and device that can accurately measure a few percent to 100 percent, let alone measure the water cut of heavy oil. When the density of crude oil is close to the density of water (930kg / m 3 ), the application of the measurement method of the kinetic principle will cause a large deviation

Abstract

A measuring method capable of continuous and on line measure the crude oil purity, water content and flow and its equipment, it includes two thermal conductive elements and one temp. sensor set obliquely in the pipe line, heater and temp. sensor are installed in thermal conductive element, by measuring the thermal diffusion rate of the two thermal conductive elements in liquid, two sets relation ship formula between thermal diffusion rate and flow, water content can be obtd. then the water content and oil water flow of crude oil can be calculated.

Description

1. Technical field [0001] The invention relates to a device capable of continuously and on-line measuring the water content of crude oil, and further relates to a device and a method for measuring the water content of crude oil in a mixed stream of crude oil and water. 2. Background technology [0002] At present, most crude oil transportation pipelines contain water, and the water content varies from a few percent to tens of percent. Measuring the water content and flow rate of crude oil is one of the most basic requirements in the process of crude oil production and transportation. The difficulty of crude oil water cut and flow measurement is that the emulsion formed by crude oil and water varies with the change of water cut. The measurement of water cut is also related to flow measurement. Therefore, so far, there is no crude oil water cut measurement method and device that can accurately measure a few percent to 100 percent, let alone measure the water cut of heavy oil. ...
