Application of technology of chemical mudding, reducing damage of reservoirs at wells drilling in the Yakutia fields during well construction

It is noted that during the initial reservoirs exposing the zone of mud filtrate invasion into near-wellbore reservoir area is forming and increasing in time. While casing cementing it increases sharply due to filtering of injected buffer fluid and cement, which does not permit to obtain a potentially possible yield. In order to stop the growth of the flushed zone after the initial exposing before stimulation after perforation the technology of chemical mudding, reducing the reservoir damage and allowing significantly to increase the well productivity factor, is developed.
