Annotation:
For a multidimensional casing-string with transitions, a cementing plug has been developed that contains an elastic body with a blind axial channel and cuffs. The body is made in the form of a cone and in such a way that each cuff seals a certain size in diameter in a multidimensional casing string. When the plug enters the latest (smallest) diameter, the inner cavity has a minimum volume (takes the form of a cylinder), and the number of sealed cuffs is maximum.
