Point Bar Numerical Simulation and Results Analysis of x-Unit in the Daqing Oilfield D Block

Abstract:

Point bar reservoir is the key development object in the late stage of oilfield development at present. In this paper, numerical simulation is done on the basis of the point bar architecture in the modeling of the point bar. Through dynamic data generating simulated well history and acquiring X-unit splitting factor, history matching is done on this basis. The numerical simulation results reveal that oil saturation has belt distribution characteristics on the pane due to the lateral accretion interlayer affect to the oil-water displacement; injection wells transverse spread is limited by the lateral accretion interbed control; by lateral accretion interlayer updip pinchout control, the remaining oil is mainly located in the middle and upper part of the lateral accretion [1,2]. Because of the above characteristics, taking horizontal wells to develop the top remaining oil of point bar has been very good results. And it has been confirmed by the further results of the numerical simulation.
