栲胶类油田化学剂的应用现状及前景

从栲胶独特的多元酚结构所具有的化学特性入手，简述了国内外栲胶类钻井液处理剂的发展历史与应用现状，以及栲胶类高温堵剂在稠油热采油藏和高温低渗透油藏中的应用现状及其研究进展。栲胶类天然材料来源广、价格低，改性后具有生物降解性和耐温性好等诸多优点，用作多功能新型油田化学剂的前景十分广阔。

Application status and prospect of quebracho oilfield chemicals

According to the chemical characteristic of polyphenol structure unique to quebracho, present application and developing history of the additives for quebracho drilling fluids are discussed. Moreover, present application and research progress of high-temperature quebracho plugging agent in the heavy oil reservoir by thermal recovery and reservoir with high -temperature and low -permeability are also introduced. Natural source of quebracho is abundant and cheap in price. There are many merits, such as biodegradability and good heat resistance after modification, and prospect of quebra-cho acting as multifunctional oilfield chemicals is very wide.
