摘　　要：设计了底水油藏水平井三维物理模型,研究了标准水平井以及不同井身轨迹水平井底水驱过程中的出水规律。从底水驱水平井开采的理论研究入手,建立了统一的、具有普遍适用性的表征出水规律的无量纲参数团—底水驱出水准数。通过建立的水平井三维物理模型的底水驱室内实验结果验证了底水驱出水准数的准确性,为底水油藏水平井实际开采过程中出水部位的预测提供了理论依据,针对出水部位开展相应的治理工作,延缓水平井底水突进。By designing the 3D horizontal well physical model in bottom water reservoir,the water breakthrough rule of standard or different well trajectory horizontal well was studied.From the horizontal well bottom water flooding exploitation theory,the unified,universal,dimensionless parameter group-the bottom water drive number to characterize the rule of water breakthrough were established.Using the 3D horizontal well physical model,the bottom water drive number was proved correct.It provides theoretical basis on how to predict the water breakthrough site during the process of exploiting horizontal well in bottom water reservoir and take corresponding measures to delay the duration of bottom water breakthrough.
