Advances on the Research of Lignin and Their Derivatives Application in Enhanced Oil Recovery

本文综述了木质素及其衍生物在三次采油中应用的最新研究进展。开发木质素磺酸盐和碱木质素制备无污染、性能好、价格低廉的新型高效环保型表面活性剂对于提高我国油田的采油率、降低成本、减少污染,具有重要的现实意义,同时也有助于制浆造纸废液中木质素资源的综合利用和对环境污染的治理。

This article gives an overview of the most recent advances on the research and application of lignin and their derivatives in enhanced oil recovery.Lignosulfonates and alkali lignin are developed to the environment-friendly surfactant with non-polluting, high-performance and low-cost qualities, which play an important part in improving the rate of oil extraction and reducing costs and pollution, at the same time, it can help comprehensive utilization of lignin resource from the waste liquid of pulping and papermaking and environmental pollution treatment.
