Abstract

The article discusses the issues of reducing non-productive drilling time during the construction of directional and horizontal wells. The main focus is on the analysis of drilling conditions in complex geological and high-temperature environments. Particular attention is paid to drilling conditions in the territory of the Republic of Uzbekistan, with a specific study of data from the Boysun and Ustyurt regions. An analysis and study of the performance of telemetry systems available on the market, as well as their main technical characteristics, have been conducted. Key factors affecting the accuracy of wellbore trajectory measurements under various geological and technical conditions are identified, which can lead to deviations in the wellbore trajectory and, consequently, to additional costs for drilling a second borehole. It is noted that the improper selection of telemetry systems during drilling results in increased well construction time due to the execution of additional, unplanned hoisting and lowering operations. Based on the conducted analysis, telemetry systems have been selected for drilling directional and horizontal wells under complex geological and high-temperature conditions for deep well construction. Various types of telemetry systems and their technical characteristics are considered, with attention given to drilling parameters and operational modes. Based on the analysis, the selected telemetry systems are recommended for application under the conditions of the Ustyurt region.
