Annotation:
The article deals with the problems of improving the quality of wells support at the fields of the Far North. The mechanisms of a filter cake formation on the wellbore walls as well as methods of its removal and fixation have been studied. Taking into account the identified factors, solutions were developed to improve the tightness of the well lining and the adhesion of the cement stone with limiting surfaces.
