Background

At the present stage, most oil production stations in oil fields in China adopt a metering separator glass tube to measure the oil production, the situation that bottom water becomes dirty or crude oil dirt particles enter the glass tube often occurs in the measuring process, the inside of the glass tube is turbid, the liquid level cannot be seen clearly, and the situation easily causes errors in oil well metering. At the moment, the metering glass tube needs to be cleaned, and the glass tube is thin inside and can reach about 2m in length, so that the glass tube is inconvenient to clean after being disassembled, and therefore, the glass tube is installed on the original equipment for cleaning.

The current cleaning method commonly adopted on site is to adopt a thin iron wire, the front end of the thin iron wire is tied with a piece of thin cotton cloth, the thin cotton cloth is put into a glass tube and is moved up and down for cleaning. But the disadvantages are as follows:

firstly, the diameter of the iron wire is about 0.5mm, the hardness is low, and when the inner surface of the glass tube is cleaned, the iron wire can be bent and deformed once being forced, so that oil stains in the glass tube cannot be thoroughly cleaned;

secondly, because the caliber of the glass tube is small, cotton cloth with large volume cannot be put in the glass tube at one time, or the cotton cloth cannot enter the glass tube;

thirdly, the phenomenon that the iron wire is clamped inside the glass tube easily occurs, if the iron wire is broken, the whole glass tube needs to be disassembled, and the operation is extremely inconvenient.

Aiming at the problems of inconvenient cleaning and incomplete cleaning of a glass tube of an oil production metering separator in the related technology, an effective solution is not provided at present.
