摘　　要： 根据多分支井的非稳态渗流特点,建立了多分支井的非稳态渗流模型,利用单支水平井的压力分布叠加得到了多分支井的压力分布.采用井筒流动与油藏流入相互作用的耦合模型,得到各种多分支井压力不稳定动态曲线,并分析了其不稳定压力动态特征.通过对多分支井压力不稳定动态曲线特征分析划分出了不同多分支井的渗流特征段,这对于多分支井试井解释和油藏评价具有重要的意义. According to the unsteady seepage characteristics of multi-lateral wells,the unsteady seepage model of the multi-lateral wells is established,and the pressure distribution of them is obtained by the superposition of the pressure distributions of mono-lateral wells.The unsteady pressure characteristic curves of various kinds of multi-lateral wells are gained from the coupling model of well-bore flow with reservoir inflow,and the characteristics of the curves are analyzed.According to the analyses,the curves are divided into some characteristic sections,which is of important significance to the well-testing interpretation of the multi-lateral wells and reservoir evaluation.
