固砂剂防砂方法的研究发展

Study and Development of Sand Consolidating Agent Methods

固砂剂防砂是一种化学固砂方法,是注入固砂剂,使地层中疏松的颗粒物质胶结。目前国内的固砂剂防砂的一些新技术,以及它们的应用和发展方向。包括:FSJ-Ⅲ酚醛树脂胶粘剂的地下合成、糠醇-2-脲-2-甲醛树脂、新型环氧-酚醛树脂、乳化脲醛树脂、改性呋喃树脂、氟硼酸等。

Sand controlling with sand consolidating agent is a chemical sand controlling method. Pulling in sand consolidating agent and make grain substance consolidate in the ground. Some new technologies and application development of Sand controlling of sand consolidating agent in the state were introduced, such as underground synthesis of FSJ - m phenolic adhesive, Furfurol/Urea/Formaldehyde Resin, novel epoxy - phenolic resin, ampholytic sulfonated phenol formaldehyde resin, modified furan resin, Fluoboric acid, and so on.
