摘要:

淀粉制剂用作泥浆处理剂，来源广，价格低，它在天然聚合物制剂中的比例，美国达到２０％以上，我国则不到１％，本文在介绍淀粉制剂的种类，性能特点和生产工艺的基础上，分析了我国用量少的原因并提出了解决的办法。

Abstract:

Starch category products are of low cost and rich in resomees as a kind of drilling fluid additives. The share of starch category products in natural polymer products is more than 20% in U. S. A., but less than 1% in China. Based on introduction of the va
