摘要:

本文通过木质素类钻井液处理剂现场使用的国内外变迁情况，探讨了８０年代末以来下降的原因。指出；铁铬木质素磺酸盐是一种高效优质价廉的降粘剂，它的应用解决了大量造纸废液的污染问题；目前应侧重于解决高价独所导致的环保问题，并研究它在聚合物不分散钻井液中的作用，以防止其应用的进一步衰减。

Abstract:

The reason that application of lignin category drilling fluid treating agent has decreased since late eighties is discussed by analysing the changing status of field applications at home and abroad. FeCr-lignosulfonate is a kind of viscosity reducer with
