CGS－2具阳离子型接技改性淀粉泥浆降滤失剂的合成

Synthesis of Cationic Graft Modified Starch Mud Fluid Loss Controlling Agent CGS-2

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.
