Abstract
Drilling and fastening of wells in hydrogen sulfide-containing highly permeable rocks is often accompanied by concomitant complications, such as absorptions of various intensities and differential sticking of the drilling tool, and with a decrease in back pressure on such formations, manifestations of fluids containing hydrogen sulfide. This degrades the parameters of process fluids and requires the preparation of new portions, causing an increase in the time and cost of well construction. Therefore, the development of drilling process fluids to improve the efficiency of well construction in highly permeable rocks containing hydrogen sulfide is an urgent task. The article presents the results of research and development of a complex of highalkaline of drilling process fluids formulations, which provides high-quality penetration and reliable fixation of highly permeable rocks containing hydrogen sulfide, with practical implementation at the fields of the Timan-Pechora oil and gas province under conditions of hydrogen sulfide aggression.
