摘要
介绍了我国近5年来钻井液用降黏剂的研究与应用情况,包括改性天然材料类(改性木质素类、改性单宁类及其他)、合成聚合物类(含羧酸基团类、含磺酸基团类、含两性离子基团类及有机硅类)和以工业废料为原料的共三大类降黏剂。近年来对聚合物类降黏剂的研究较多。
This article reviews researches and uses of viscosity reducers （VRs） for water base drilling fluids in China in recent 5 years. These VRs are presented in three classes： those based on modified natural materials （lignins, tannins, and others）; thsoe based on synthetic polymers with carboxylate, sulfonate and amphoteric functionalities and polysilicones; and those made from industrial solid wastes. The most attention is given to synthetic polymers.
