The invention provides a polyether amine compound. The chemical structural formula of the polyether amine compound is as shown in the specification, wherein n and m are selected from natural numbers 1-20, and R1 and R2 are selected from H, methyl, ethyl and isopropyl. The polyether amine compound provided by the invention is used as a clay stabilizer in the operation process of gas well reparation; and by virtue of proper polymer molecular weight as well as type and number of compound functional groups, the prepared compound has a good clay anti-swelling rate, and the problems existing in compatibility, acid-alkali resistance and the like of partial ionic clay stabilizers which are adopted currently are effectively overcome.
