摘要
Abstract
A heat-resistant and high strength modified gel was prepared by incorporating modified organic bentonite with silane coupling agent KH550 as a modifier into a gel system with acrylamide as the main chain material,tert-butyl hydroperoxide as the high-temperature initiator,and methylhydroquinone as the high-temperature polymerization inhibitor.The optimal conditions for maximum gel strength and the salt and alkaline tolerance of gel were investigated.The experimental results show that the gel has high strength and good salt and alkaline tolerance when the modified organic bentonite is 0.5 g and the salinity is 20 g/L.Based on the simulated plugging experiment results,the plugging rate can reach more than 87.29%.关键词
