Study on Remaining Oil at High Water Cut Stage of the Offshore Strong Bottom Water Reservoir

C oilfield is a heavy oil field developed by horizontal wells and single sand body in Bohai oilfield. The edge bottom water of the reservoir active natural energy development mode adopted. comprehensive cut was 95.3%, which had entered stage high production. Some reservoirs were limited crude viscosity column height. Under condition existing well pattern, some reserves not produced or degree production low, control high, so there room for tapping potential remaining oil. This paper studied rising law ridge engineering method, guided infilling limit reservoir. At same time, combined with research results fine description, geological model established, numerical simulation carried out, distribution analyzed. Through this study, we could understand flooding period reservoir, as to provide guidance strategy type period.
