Analysis of Enhanced Oil Recovery Technology in Extra-high Water Cut Period in Oilfield
Institute of Geology, No.6 Oil Production Plant of Daqing Oilfield Company, Zip code: 163000 China
Most onshore oil fields in China are in the later stage of development, and the water content is more than 90%, which increases the difficulty of remaining oil mining. In order to improve the oil production, it is necessary to develop a variety of oil recovery technologies, increase the oil field space pressure, weaken the oil viscosity, and improve the recovery factor. Taking L oilfield as an example, the paper briefly expounds the characteristics of extra-high water cut period, and on this basis, puts forward recovery technology, grasps development rules, and realizes technological innovation. The accumulative oil production reaches 2.32 million tons, and the recovery factor increases by 9%, thus providing reference for related workers.
Key words: Oilfield / Extra high water cut stage / Recovery techniques
