Abstract
Produced water is the largest by-product of oil production. Studying its high-efficiency treatment technology is one of the key issues in the sustainable development of oilfields. The adsorption has the characteristics of low cost, high efficiency and no secondary pollution, and has significant effects in the treatment of produced water. This paper introduces the adsorption technology. The research progress of the domestic and international adsorption treatment of oilfield produced water was summarized. The effects of different adsorbents on oilfield produced water treatment are briefly described, which points out a new research direction for the development of future adsorbent technology.
