AP23487129 "Improving the extraction and quality of groundwater through the development of an innovative borehole water treatment system for the water supply of the population of Kazakhstan"

Relevance

The use of technologies developed in the project in production, which make it possible to take advantage of block filters during their transportation and loose sprinkles during mining, will significantly improve the quality of work by: reducing the consumption of gravel material and the time it takes to transport it to the aquifer; preventing the hanging of gravel material during its transportation along the borehole; forming visual inspection on the daytime surface of the gravel sprinkle and, if necessary, the formation of a multi-layer sprinkle with the specified parameters; eliminating the likelihood of gaping voids; reducing the likelihood of sanding; reducing hydraulic resistance while increasing effective porosity, etc. At the same time, the well will be equipped with a gravel filter with geometric and hydraulic parameters set and unchanged during transportation and installation into the aquifer, and due to this, an increase in the inter-repair period; reducing the number of drilled wells by at least two times

Purpose

The aim is to create a comprehensive device for automatic continuous monitoring of four parameters of drilling mud: its density, conditional viscosity, plastic viscosity and dynamic shear stress. These are the most important parameters of drilling mud quality, which play a crucial role in preventing accidents and complications in the borehole, as well as in choosing the necessary technological equipment

Expected and achieved results

For the first time, an inversion-based eco-friendly technology has been developed for equipping drilling wells with gravel filters. This technology will significantly improve the efficiency of hydrogeological well operations: increasing flow rate, service life, and mean time between repairs, reducing extraction costs, and improving water quality. Methods for enhancing the quality of gravel backfill in the filter and technologies to prevent material suspension during transportation were also developed.
