Challenges and strategies of water system in extra high water cut development stage

Abstract

At present, China’s oil fields are in the period of ultra-high water cut production, production capacity continues to decline, the cost of water resources continues to rise, the input and operating costs of water supply system continue to increase, it is very difficult to reduce costs, improve benefits; With the change of chemical flooding to thin and poor formation, the exploitation and utilization of heavy oil in Fuyu Oilfield and its surrounding area require higher water quality. At present, it is urgent to solve the fine treatment of mining water and the recovery technology of fracturing wastewater. Due to the aging of the station, there are numerous safety and environmental issues, so the work of reducing energy consumption is onerous. Faced with many new problems, the water industry must plan ahead, control investment, reduce costs, maintain water quality, improve efficiency, and develop and reserve suitable technologies.
