摘要: 针对二层油藏分层注采实际情况,在分析水平管流、垂直管流、配水嘴嘴流等沿程压降的基础上,基于节点分析原理,建立了二层油藏分层注采系统节点分析数学模型,考虑了层间、注采井间相互作用,大大提高了节点分析的可靠性;通过理论分析和实例计算,确定了分层配产配注量和注入压力,使注采系统处于平衡生产状态,并对多层油藏的节点分析具有一定借鉴意义和理论意义。

Abstract: Aiming at the practical situation of layered water flooding recovery in twolayer reservoir,on the basis of analyzing horizontal flow,vertical flow and choke flow,as well the mechanism of nodal analysis,nodal analysis mathematic model of layered flooding recovery system of two-layer reservoir is set up with the consideration of interactions among the layers,producers and injectors,which greatly improve the reliability of nodal analysis.Meanwhile,by means of theoretical analysis and practical calculation,the layered output,injection rate and pressure are determined,which makes the injection-withdrawal system the status of balanced production,and is meaningful and valuable to the nodal analysis of layered reservoir.

Key words: nodal analysis, layered water flooding recovery, mathematical model, IWR, flow rate
