Crude oil emulsion particle size detection method and device, and readable storage medium

Abstract

The invention discloses a crude oil emulsion particle size detection method and device, and a readable storage medium. The method comprises the following steps: S1, carrying out the filtering and binarization on a crude oil emulsion microscopic image to obtain an emulsion binary image; S2, marking all connected domains in the emulsion binary image through a connected domain marking method; to be specific, corresponding one connected domain to one liquid drop; and S3, acquiring an area and perimeter of the liquid drop corresponding to the connected domain through the connected domain and acquiring the particle size of the liquid drop according to the area and perimeter of the liquid drop. According to the invention, all connected domains in the emulsion binary image are marked by the connected domain marking method and one connected domain corresponds to one liquid drop, so that the particle size of the liquid drop is conveniently and quickly counted; the statistics of the number of internal and edge pixels of the connected domain is performed to calculate the area and perimeter of the liquid drop and the particle size of the liquid drop is obtained based on the area and perimeter of the liquid drop, so that the calculation process is visual and convenient. Compared with other methods, the disclosed method has advantages of being operated fast and occupying small memory space.

Description

technical field [0001] The invention belongs to the field of microcosmic detection of crude oil emulsion, and relates to a particle size detection method, device and readable storage medium of crude oil emulsion. Background technique [0002] In the petroleum industry, the extracted crude oil is a mixed solution of oil, water, and emulsion, and contains a small amount of impurities such as sediment. In order to obtain relatively pure oil, it is necessary to send the crude oil to the oil field joint station, store it in the crude oil storage tank, and go through multiple processes such as sedimentation, demulsification, and separation, before separating the oil that meets the smelting standard. This series of processes Process is very important in oil storage and transportation. The characteristics of the emulsion droplet size and distribution of the crude oil waiting for oil-water separation in the settling tank will change at any time with the change of settling time, demu...

However, the indirect measurement method of droplet size based on the average droplet migration rate can only calculate the average particle size, but not the particle size of a single droplet, and there are certain limitations in application, and the distribution of all droplets cannot be analyzed

The direct measurement method of droplet size based on image processing can not only measure the particle size of a single droplet, but also calculate the average particle size, which is superior to the indirect measurement method of droplet size based on the average migration rate of droplets. However, there is no Given the specific implementation process, the measurement speed is relatively slow, and the system development environment is relatively old, and the compatibility is insufficient
