抗高温水泥浆降失水剂 SCF-1的合成及性能评价
Synthesis and property evaluation of high temperature resistant fluid loss additive SCF-1 for cement slurry
摘要
Abstract
In this paper ,a high temperature resistant fluid loss additive for cement slurry was synthesized using DMAA ,AHPS ,AMPS and AA ,and was characterized through infrared spectrum . The synthetical performances of the cement slurry added with fluid loss additive were evaluated .The results show that the API fluid loss of that cement slurry can be controlled below 50 mL ,and its temperature tolerance can be up to 150 ℃ .The thickening time of cement slurry is extended slightly , yet its compressing strength is decreased lightly and its water precipitation resistance is also improved .Its salt‐resistance performance is enough to reach 36% of salt concentration .关键词
