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

Abstract

The invention discloses a crude oil emulsion particle size detection method, device and readable storage medium, comprising the following steps: S1: filtering and binarizing the micrograph of the crude oil emulsion to obtain a binary image of the emulsion; S2: Mark all the connected domains in the binary image of the emulsion by the connected domain marking method, one connected domain corresponds to one droplet; S3: get the area and perimeter of the droplet corresponding to the connected domain through the connected domain, and pass the area and circumference of the droplet grow to obtain the droplet size. Mark all the connected domains in the binary image of the emulsion by the connected domain marking method, one connected domain corresponds to one droplet, which is convenient and fast to count the particle size of the droplet; calculate the area and perimeter of the droplet by counting the number of pixels inside and outside the connected domain , the particle size of the droplet is obtained through the area and perimeter of the droplet. The calculation process is intuitive and convenient, much faster than other methods, and takes up less 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...

Problems solved by technology

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
