国内改性木质素类降粘剂研究进展

Study on the Development of National Modification Lignin Viscosity Reducer

简要介绍了我国木质素资源的利用情况及木质素磺酸盐的接枝改性方法,对我国近年来改性木质素类降粘剂的研究与应用进行了综述,并对我国钻井液用降粘剂的发展前景进行了展望。结果表明,木质素资源丰富,应加强其研究与应用开发力度,以提高现有木质素类降粘剂的性能,满足石油工业发展的需要。

The paper briefly introduced the utilization of lignin in China and the method of grafting modification of lignosulfonate. The research and application of the modified lignin viscosity reducer in China were reviewed in recent years and prospected the development of viscosity reducer used in drilling fluid. The result showed that lignin is rich and more attention should be paid in its study and development, so as to meet the development of petroleum industry.
