| 摘 要： | 对淀粉醚化产物和淀粉接枝改性产品的性能、生产工艺和应用进行了介绍。淀粉改性产物包括淀粉醚化产物和接枝共聚产物，淀粉醚化产物是一种抗盐性能好的钻井液处理剂，适合用作饱和盐水钻井液降滤失剂，其缺点是抗温能力差，而淀粉接枝共聚产物不仅具有良好的抗盐性能，且抗温能力大大提高，可用于各种类型的水基钻井液。

| Abstract: | The performances,production process and application of modified starch additive prepared by etherification and graft copolymerization were introduced.Modified starch included etherified starch and graft copolymer ized starch.The former had good salt-tolerance,but it had poor temperature resistance.The latter not only had good salt-resistance,but also had improved temperature resistance,and it could be used in all kinds of water based drilling fluids. |

| Keywords: | starch modified product drilling fluid additive carboxymethyl starch hydroxypropyl starch starch grafted copolymer |
