摘要
介绍具阳离子型淀粉接枝改性产物CGS-2的合成方法,并就其泥浆性能进行了室内初步评价。结果表明,CGS-2有明显的降失水效果,较强的抗盐、抗温能力和较好的防塌效果。
This paper deals with the synthesis of CGS--2 fluid loss controlling agent for mud.COS-2 is a graft modified product of cationic starch The mud characteristic of OGS-2 was evaluated in laboratory,the experimental results show that CGS-2 has the following properties:obvious filtration-reducing, reltively strong salt resistance and heat resistance abilities, and fairly good anti-collapse.
