Study of water treatment process for Bohai low permeability oilfield
The development of Bohai low permeability oilfields is an important component of future production succession,stable production and increased production.However,the existing offshore low permeability water treatment scale is small,and there are significant differences in process flow.By summarizing the existing processes and application effects of low permeability water treatment at sea,and comparing and analyzing the characteristics of membrane filtration and modified fiber ball filter technologies,this study proposes a low permeability water treatment process for Bohai oilfield.The proposed process includes in-clined plate degreaser-air float-walnut shell filter-double medium filter-membrane filtration/modified fiber ball filter.Additionally,suggestions are provided for the development of low permeability water treatment technology and process design in order to guide the develop-ment and design of low permeability oilfields,as well as promote their further utilization.
