Bench studies of the process of transporting an inverse gravel filter of block type along the well

Abstract

Abstract The purpose of the study is to develop a technology for fresh water treatment in deep hydrogeological wells with productive horizons represented by medium-grained, fine-grained, and silty sands by equipping their intake part with block-type inverse gravel filters. Experimental studies were carried out using provisions of the general theory of scientific experiment and the theory of random processes. A theory concerning the possibility of equipping the water intake part of hydrogeological wells, being more than 200 m deep, with block-type inverse gravel filters using the proposed technology was further developed. For the first time, the dependence of the maximum depth of transporting block-type inverse gravel filters on the length of their section, the mass concentration of a binding agent, and the ambient temperature was established. A scope of the proposed technology was substantiated. A range of depths for equipping with block-type inverse gravel filters depending on the mass concentration of a binding agent in the polymer-gravel filter element and the length of its section was substantiated.
