板栗刺壳栲胶制备油田用降粘剂的初步研究

A preliminary study on the chestnut shell extract prepared with oil viscosity reducer

采用我国年产生150万t的林产废弃物板栗刺壳进行栲胶的提取、改性,将其初步制备成一种钻井液用降粘剂,以期为寻找环境友好的降粘剂进行一些前期的工作。

In this paper,China's annual output of 1.5 million tons of forest wastes-Chinese chestnut thorns shell were extracted,modified and initially prepared into a drilling fluid viscosity reducer,via this work,this paper hopes that some of the previous jobs of environmentally friendly viscosity reducer could be explored.
