Abstract

The invention provides anionic polyether modified siloxane, a preparation method thereof, an imbibition agent composition containing the anionic polyether modified siloxane, an oil-displacing agent containing the anionic polyether modified siloxane, and application of the imbibition agent composition and the oil-displacing agent. The anionic polyether modified siloxane disclosed by the invention shows excellent oil resistance and temperature resistance, and particularly, the composition obtained by compounding the anionic polyether modified siloxane with an anionic-nonionic surfactant meeting specific conditions has excellent temperature resistance and salt resistance and also shows super-strong wetting change performance, so that the imbibition efficiency of the composition is improved.
