Annotation:

Within the framework of the article, grouting and repair compounds and various methods for carrying out repair and insulation works (hereinafter RIW) in oil and gas wells have been studied. An innovative method has been proposed (patent No 2 684 932 "Method of repair-isolation work in wells"), which allows increasing the success of repair and insulation works (RIW) in a well at low injectivity in the zone of the insulation work.
