The invention provides a method for quickly detecting stability of paraffin emulsion, comprising: firstly determining the correlation between static layering time of prior emulsion and the time for realizing breaking of emulsion by the prior emulsion by means of mechanical force; then, breaking of the emulsion to be detected by means of the mechanical force, and recording the time for breaking of the emulsion; finally, obtaining the static layering time according to the time for breaking of the emulsion to be detected. The method can accurately and rapidly detect the stability of the quality of the emulsion in an objective way, so as to solve the problem that the traditional static method requires to spend a long time on waiting.
