摘　　要：对落叶松栲胶高温凝胶堵剂的性能作了系统研究。该堵剂的典型配方为：栲胶６％、ＰＦ混合物（苯酚和甲醛）４％、其余为水；堵剂配制液的ｐＨ为１０～１１，粘度２０．５ｍＰａ·ｓ，在２００～３００℃范围内，胶凝反应时间在１４～４８ｈ之间。生成的凝胶具有强度高、封堵率高、能耐３００℃高温、抗盐性好等特点。A heat resistant plugging agent, which can be used in thermorecovery of petroleum industry, is made from larch tannin extract, phenol, aldehyde and water. A typical composition of the plugging agent is: larch tannin extract 6%, a phenol formaldehyde compound 4% and balance water. The properties of the plugging agent are discussed. The pH value of the gel forming fluid is 10～11. The viscosity is 20 5 mPa·s. The gelation time varies in the range of 14～48 h within temperature 200～300℃. The upper limit of temperature for use of the plugging agent attains 300℃. The gel formed has good strength and plugging efficiency.
