| 摘 要： | 利用油藏流体渗流模型和水平井筒内流体流动模型 ,推导出了油藏井筒流体流动耦合模型 ,在该模型中考虑了两种流动的相互作用和影响。建立了以水平井产量为目标函数、以孔眼分布为决策变量的优化模型 ,将其计算结果与均匀流入剖面、均匀射孔分布的结果进行了对比。由于优化模型中考虑了水平井筒内变质量流的影响 ,从而可为现场水平井的优化设计提供理论依据。 |

| Abstract: | A model for coupling resevoir wellbore fluid patterns was deduced from the seepage flow model of resevoir fluid and the fluid flow model of horizontal wellbore. The interactive influences between two fluids are considered in the present model. An optimization model is presented, in which the production of the horizontal well is regarded as an objective function and the perforation distribution as a decision making variable. The present model was compared with the former model for uniform influx and uniform perforation tunnels' distribution. The effect of variable mass flow was considered in the optimized model. This model may provide a theoretical basis for the optimization design of horizontal wells. |
| Keywords: | horizontal well perforation tunnels' distribution optimization model variable mass flow |
