There are many edge and bottom water reservoirs in the Bohai Oilfield,which are prone to water flooding during the middle and later stages of production,hindering oil and gas production.In recent years,Bohai Oilfield has also been continuously exploring new water control technologies,but the water control effect and investment are often unsatisfactory.Taking the practice of CFD Oilfield as an example,this paper explores the effective water control technology under the situation of cost reduction and efficiency increase,aiming to save costs and ensure certain stable oil and water control effects.
