摘　　要：八甲基环四硅氧烷和四甲基环四硅氧烷在强酸性离子交换树脂的引发下发生聚合,得到中间体含氢聚硅氧烷。中间体再与3-丁烯-1-醇在催化剂铂(0)-1,3-二乙烯-1,1,3,3-四甲基二硅氧烷的催化下发生反应,得到了一种羟基接枝聚硅氧烷,对其进行了结构表征,并对其耐温能力以及对储层岩石(砂岩)表面润湿性的调节能力进行了性能评价。结果表明,该羟基接枝聚硅氧烷有着很好的耐高温性能,并且可以在240℃的高温环境下将砂岩表面润湿性调节至中间润湿状态,能够有效阻止钻井液中水相对储层岩石的侵入,降低水锁损害,保护油气储层。An intermediate product is obtained by polymerization between 1,3,5,7-tetramethylcyclo-tetrasiloxane(D_(4)^(H))and octamethylcyclotetrasiloxane(D_(4))under the initiation of Purolite■CT175.The intermediate is then reacted with 3-buten-1-ol under the catalysis of platinum(0)-1,3-divinyl-1,1,3,3-tetramethyldisiloxane to obtain a hydroxy-modified polysiloxane.The structure of the product was characterized,and the temperature tolerance and ability to modulate the wettability of the sandstone surface were evaluated.The results show that the polymer has good temperature resistance and can adjust the wettability of the sandstone surface to an intermediate wettability state at a high temperature of 240℃,which can effectively reduce the loss of water phase in the drilling fluid and protect oil and gas reservoir.
