摘要：Years of oilfield development practice indicates that the quality of injected water plays an important role in the water-injection process to improve the development effect. The low-permeability reservoirs have low yields and strict requirements on water quality indicators, and it is urgent to study the process of oilfield produced water treatment. The damage source and mechanism of re-injection water was discussed, and the compatibility between the reinjection water and the formation of water was analyzed and evaluated. The treatment process of water reinjection was studied, and the recommended indexes on injection water quality for low-permeability reservoirs for water-flooding development was given in this paper that provides a theoretical basis for the research of oilfield water-flooding development and injection water quality indicators for the future.
