Gelation Behavior of the Delayed Crosslinking Amphiphilic Polymer Gel Based on Multiple Emulsions
(0) In the study presented in this paper, multiple emulsions were prepared to form delayed crosslinking amphiphilic polymer gel in order to achieve deep conformance control in oilfield development.Soluble amphiphilic polymer was employed as the main polymer agent,uotropine, resorcinol as the cross-linking agent and citric acid as an additive.Emulsion dehydration experiments were conducted to screen the formulation of the delayed cross-linked amphiphilic polymer gel, and the impact of the additives, emulsifiers and different oil phases on the gelling properties also was studied.The results show that the amount of citric acid had an important impact on the gelling properties;when the amount of citric acid in the external aqueous phase was less than 0.2%, the gel could not form.The thermal stability of the gelling systems stabilized by the Span80/T20 was better, and the crosslinking of the gel could be delayed by about 8-9 days with strong gel strength.
