采用分段等分方法建立水平井段流态模型,以水平井段线性稳态管流为基础,通过分析计算形成了利用孔密控制水平段流出剖面形态的方法。在水平井生产压差不同的井段通过不同孔密调整生产剖面。通过在胜利油田东辛采油厂辛172-平1,辛133平1等水平井的应用,有效控制底水推进,延迟见水时间,延长油井生产周期。
By using the method of piecewise equalization, the flow field model of horizontal well section is established. Based on the linear steady state flow in the horizontal well section, the method of controlling the outflow profile of the horizontal section is established through the analysis and calculation. In the production of horizontal wells with different pressure well section through different hole density adjustment production profile. Through the application of such horizontal wells as Xin 172- Ping 1 and Xin 133 Ping 1 in Dongxin Oil Production Plant of Shengli Oilfield, the bottom water advancement can be effectively controlled, the water seepage time can be delayed, and the oil well production cycle can be prolonged.
