The choice of optimal methods for the development of water wells in the conditions of the Tonirekshin field (Kazakhstan)

Abstract

Purpose. Scientific substantiation of the application of technology for the development of water wells in the conditions of the Tonirekshin field of the Mangystau Peninsula. Methodology. The tasks were solved by a complex research method, which includes a review and generalization of literary and patent sources, analytical studies on existing methods for the development of water wells and their interpretation in relation to the geological and technical conditions of the Tonirekshin groundwater field. Findings. The main exploitable aquifers that are part of the Tonirekshin groundwater field are considered and a critical analysis of information on the geological and hydrogeological features of the basin is made. The requirements for the process of development of water wells for the field conditions are formulated. Well-known advanced well development methods are analyzed. Their advantages, disadvantages and compliance with the requirements are revealed. The implosion method was chosen as the best method for the development of water wells in the conditions of the Tonirekshin field. Originality. For the first time, for the geological and technical conditions of the Tonirekshin groundwater field, using the method of expert assessments, the choice of the optimal method for the development of water wells has been scientifically substantiated, which ensures decolmatation of the near-wellbore zone and the maximum flow rate of high-quality water for domestic and drinking water supply. Practical value. For the specific geological and technical conditions of the Tonirekshin groundwater field, the most suitable method for the development of water wells was chosen – the implosion method. The application of this method will provide a significant increase in well flow rate and a solution to the problem of oasis irrigation of lands in the Beineu district of the Mangystau region (Kazakhstan).
