1. The method of well completion, in which:! provide at least one hole in the wall of the pipe string, a multi-position valve associated with this at least one hole, and at least one external insulating device on said pipe,! place the column in the wellbore,! isolate part of the wellbore with an isolating device,! hydraulic fracturing is carried out in an isolated part of the wellbore through said at least one hole when it is substantially free! said valve is positioned to allow flow through the filter and said at least one hole after hydraulic fracturing. ! 2. The method according to claim 1, including:! using a launch string to position the aforementioned pipe string in the wellbore,! fixing said pipe string in the wellbore regardless of the launch string,! control of the on-off valve by means of a launch column. ! 3. The method according to claim 2, in which the call inflow through the launch column. ! 4. The method according to claim 1, including:! use of a multi-position valve made in the form of a mobile clutch! determination of the position of the full opening of the aforementioned hole in the wall of the pipe string with or without overlapping this hole with the specified coupling,! positioning of the hole in the coupling with the filter material inside it in line with the hole in the wall of the pipe string. !5. The method according to claim 4, in which a free hole is provided in the coupling and this free hole is combined with said hole in the wall before
