The Synthesis Of Hyperbranched Polyacrylamide And Study Of Dual Crosslinked Gel Plugging Agent

Because there are three dimensional spherical stereo structure of hyperbranched polymer and In a wide range of highly branched and end groups.Can show compl etely different with other polymer properties.Compared with the corresponding linear molecule excellent solubility,high rheological variation,low viscosity and a lot can be modified at the end of the functional group and a series of unique physical and chemical properties.Especially the application of hyperbranched polyacrylamide is m ore widely,synthesis method is relatively mature.In paper making,textile and medica l field shows a good application prospect.Synthesis of hyperbranched with cationic polyacrylamide.The infrared spectrum analysis was carried out on the product,And using rotational viscometer and comp uting Have had the polymer specific viscosity.And then discusses the Reaction tem perature,reaction time and dosage of initiator the impact on the viscosity of produc t.Studied the dual crosslinking plugging agent formula,Through the experiment ev aluation of influence factor like the environmental temperature,cation of formation water type of hyperbranched polypropylene amide gel plugging agent.Also type of h yperbranched polypropylene amide gel plugging agent,within the formation of sheari ng action is simulated.Based on hyperbranched polyacrylamide plugging agent plugging simulation exp eriment,hyperbranched polyacrylamide plugging agent for the artificial core pluggin g evaluation,the experimental results show that an effective plugging effect.
