The Rules of Remaining Oil Distribution and Measures for Potential Tapping in Wangji Oilfield

Wangji Oilfield was a complex fault block reservoir,it was constrained by the fault block pattern,its injection-production patterns was of low degree of perfection and reservoir heterogeneity was serious,plane adjustment was difficult during the development process,which caused low water drive control degree,low oil producing degree and low fluid producing degree in Wangji Oilfield.To improve its development effect,residual oil distribution rules are studied,the corresponding countermeasures for tapping the potential of remaining oil are proposed,it achieves better development results finally.
