Point Bar Numerical Simulation and Results Analysis in the Daqing Oilfield D Block

摘要

Point bar reservoir is the key development object in the late development of Daqing Oilfield, in this paper, the numerical simulation based on the construction of the point bar is carried out on the basis of the modeling of the point bar. Through dynamic data generating simulated well history and acquiring X-unit splitting factor, carry out history matching on this basic. The results of numerical simulations reveal that oil saturation has belt distribution characteristics on the pane is influenced by the lateral accretion interlayer on oil-water flooding, by lateral accretion interlayer updip pinchout control, the remaining oil is mainly located in the middle and upper part of the lateral accretion. In view of the above characteristics, using horizontal wells to develop the remaining oil on the top of point bar has good results, and it has been confirmed by the further results of the numerical simulation.
