Abstract
A microscopic and macroscopic evaluation method for a dual-effect hydrate inhibitor is provided. The method is applicable to the performance evaluation of traditional thermodynamic inhibitors and kinetic inhibitors. The present invention comprehensively evaluates the dual-effect hydrate inhibitor microscopically and macroscopically through a microscopic evaluation device and a macroscopic evaluation device, thereby more intuitively and efficiently screening out the dual-effect inhibitor with excellent performance. The present invention explains the action mechanism of the dual-effect inhibitor microscopically, accurately evaluate the effects of the inhibitor in two aspects of particle aggregation and particle adhesion, and provide a theoretical basis for screening the dual-effect inhibitor. Moreover, the present invention can verify the screened inhibitor macroscopically by using a flow evaluation device close to a field working condition to obtain the action effects of the dual-effect inhibitor under different production parameters, so that the comprehensive and multi-angle performance evaluation of the dual-effect inhibitor is achieved.
