摘　　要：为解决单一的冻胶或泡沫体系不能满足高温高盐油藏的选择性堵水问题,研究了结合冻胶和泡沫优点的冻胶泡沫体系,并向体系中引入了抗温抗盐添加剂来增强其抗温抗盐能力。以成胶时间、成胶强度、脱水率和泡沫特征综合值为指标,优选出了冻胶泡沫体系配方,考察了温度和无机盐对冻胶体系性能的影响。结果表明,该冻胶泡沫体系配方为:0.6%~0.7%Z4聚合物+0.4%~0.5%酚醛交联剂+0.3%稳定剂+0.3%发泡剂B,该体系抗温抗盐性能优良。岩心驱替实验表明,冻胶泡沫体系能够选择性地进入渗透率高的地层,并显著降低其渗透率,提高低渗层的开采率,表现出较强的选择性堵水能力。In order to solve the single gel or foam system can not meet the selective plugging requirement of high temperature and high salinity reservoirs problem,the gel foam system combining the advantages of gel and foam was studied,and the additives of temperature and salt resistance were added to the system to enhance its ability to resist temperature and salt.Taking gelation time,gelation strength,dehydration rate and foam characteristics as indicators,to optimize formulation of the gel foam system,the effects of temperature and inorganic salt on the properties of the system were investigated.The result showed that the gel foam system formula was:0.6%~0.7%Z4 polymer+0.4%~0.5%phenolic cross-linking agent+0.3%stabilizer+0.3%foaming agent B,the system had excellent temperature and salt resistance.Core displacement experiments show that the gel foam system can selectively enter the formation with high permeability,and significantly reduce its permeability,improve the rate of low permeable layer,and exhibit a strong selective water shutoff capacity.
