Analysis of the width of the gravic back of the gravel filters of drilling wells

Abstract

The purpose of the scientific study is to analyze the width of the gravel dump for gravel borehole filters. The main scientific approach in the solution of the goal was a scientific analysis of the existing production and experimental experience of selecting the width of gravel dumps for gravel filters. In the article, the analysis of the differences in the coverings is performed depending on the degree of interlayering. Reducing the interlayer coefficient leads to a decrease in the thickness of the coating, which also leads to the sanding of the wells. Therefore, on the way improvement of filtering properties of gravel filters, while excluding sanding, is the use of two- or multi-layer filters. The results of the research will be used for the design of gravel filters. Practical value is to improve the filtration properties of gravel filters
