摘　　要：水平井中采用中心管完井可以降低水锥对水平井开发底水油藏的影响。采用线汇叠加和镜像反映原理推导出底水均质油藏单相稳态流动势分布,针对实际水平井不可能绝对水平,因此高虑了高差影响。根据质量守恒和动量原理得到影响井筒压力分布的压降模型,油藏和井筒的相互影响得到中心管完井的耦合模型及求解思路。实例计算结果表明中心管完井能够降低跟端的大压差,平缓整个剖面的流入量,从而达到控锥的效果。Stinger completion can reduce the water coning influence in the horizontal well.Because actual horizontal well can't be absolutely level,hydrostatic was considered in deducing potential distribution of single flow in water homogeneous reservoirs,which adopted liner superimpose and reflection mirror principle.According to mass conservation and momentum principle,the model of pressure drop in well bore that affects pressure distribution can be achieved.There is interaction between reservoir and well bore,so the model of stinger completion and solutions can be received by coupling them.Example calculation showed larger pressure drawdown at heel could be reduced and flatten inflow profile by stinger completion to achieve control water coning.
