Preparation and Laboratory Study of Cationic Copolymer Clay Stabilizer PDA
In this paper,we introduced the method of preparing cationic copolymer clay stabilizer PDA and something about its laboratory study.Dimethyl diallyl ammonium chloride (DMDAAC) and acrylamide (AM) were the reaction materials,and potassium persulfate was the initiating agent,which was used to synthesize the cationic copolymer clay stabilizer PDA.Through laboratory experiments,the performance of clay stabilizer PDA was evaluated,and the results were as follows:the anti-swelling performance of PDA was better than that of KCl solution and another cationic copolymer clay stabilizer PTE.The swelling ratio of 1.0% PDA clay stabilizer was only 15.3% and anti-swelling ratio was more than 72.0%.Under the temperature of 25 ℃ to 150℃,the anti-swelling performance was still stable.Furthermore,clay stabilizer PDA performed well in resisting salt and calcium at normal temperature,and the average damage ratio of natural cores was less than 17.5%.
