, by cationic raw material salt corresponding with concentrated acid reaction generation preparation and application method the invention discloses a kind of water-base drilling fluid with ionic liquid inhibitor, comprising the following steps: (1), the cation raw material is one of alkylamine, phenol, aniline；The concentrated acid is selected from one of concentrated hydrochloric acid, concentrated phosphoric acid；(2), which is reacted in a solvent to obtain object ion liquid inhibitor with anion source；The anion source is AlCl 3 、FeCl 3 、ZnCl 2 One of, or contain RCOO ‑ 、SbF 6 ‑ One of group salt.Ionic liquid inhibitor and drilling fluid in the present invention have good compatibility, and rejection is excellent, under identical condition, the rate of recovery than clear water is higher by 39%, it is higher by 13% than 5% KCl slurry, it is close with common amido inhibitor, blistering is but led to the problem of without it. |
