根据油田地质特征，应用油藏数值模拟方法对比分析了红南油田白垩系油藏下油组应用水平井与直井的开采效果，论证了应用水平井开发的可行性。同时根据油田地质特征及油藏数位模拟进行水平井地质设计、产能分析，确定其合理产能。通过与油田生产动态资料相对比，表明了水平井对底水油藏具有较好的开发效果，水平井产能的确定结果是可信的，其方法也是可行的。
According to the geological characteristics of oilfields, the numerical simulation method of reservoir is used to analyze the exploitation effect of horizontal well and vertical well in Cretaceous reservoir of Cretaceous reservoir in Hongnan Oilfield, and the feasibility of applying horizontal well is demonstrated. At the same time, according to the geological characteristics of oilfield and reservoir digital simulation of horizontal well geological design, capacity analysis to determine its reasonable capacity. Compared with the dynamic data of oilfield production, it shows that the horizontal well has a good development effect on the bottom water reservoir. The determination of horizontal well productivity is credible, and the method is feasible.
