| 摘 要： | 简要介绍了成膜型降失水剂防窜防漏机理.考察了成膜型降失水剂对A,B,C 3种G级油井水泥性能的影响.结果表明,在同一交联度条件下,降失水剂在3种水泥中的表现不同,当交联度为1/30时,A水泥的失水量可以控制在50 mL以内,但是B水泥和C水泥常压养护后稠度太高；交联度为1/70时,B水泥和C水泥的失水量可以控制在50 ...

| Abstract: | The article briefly described anti-channeling and leak-proof mechanism of film-forming fluid loss additive.The Effects of film-forming fluid loss additive on the performances of Class G cements including A,B and C were investigated.The results show that under the same crosslinking degree,the performances of three kinds of cement were different,when crosslinking degree was 1/30,fluid loss of A cement could be controlled under 50 mL,but the consistency of cement B and C after curing was too high;when cross-li... |
