Keywords: high-alkaline formulations of drilling process fluids, highly permeable rocks, absorption, differential sticking, hydrogen sulfide

Annotation:

Drilling and cementing of highly permeable reservoirs containing hydrogen sulfide in the fields of the Timan-Pechora oil- and gas-bearing province is often accompanied by the occurrence of concomitant complications: hydrogen sulfide aggression, absorption of various intensity and differential sticking of the drilling tool. Therefore, the development of drilling process fluids for high-quality and accident-free well construction in highly permeable deposits containing hydrogen sulfide is an urgent task. The article presents the results of the development of a complex of formulations for drilling process fluids, which provides high-quality and trouble-free opening and fastening of highly permeable rocks containing hydrogen sulfide.
