Abstract

In the process of drilling oil and gas wells, abnormally low reservoir pressures (ANPD) and abnormally high reservoir pressures (AVPD) occur mainly in highly permeable, highly porous, highly drained sediments or in the productive part of the well section, where drilling is complicated due to the difficulty of selecting appropriate drilling fluids to create the necessary back pressure on the formation to avoid leaving flushing liquids into the reservoir from partial to catastrophic in nature or by oil and gas events. This article is devoted to one of the most pressing issues in the field of oil and gas well drilling, where geological complications associated with catastrophic waste of drilling fluids and oil and gas occurrences, which are costly, are common. For effective isolation of geologically complicated intervals, a new method of installing grouting bridges is proposed, where all operations will be carried out by specific calculations to determine the main technological parameters. The calculations were performed using the actual data from well No. 90 of the Kokdumalak gas and oil field in the Bukhara-Khiva oil and gas region of the Republic of Uzbekistan.
