本文以评价边底水油藏水平井产能及影响因素为总体目标，在国内外文献调研基础上，采用镜像反映原理和势的叠加理论推导出边底水油藏水平井产能公式，然后考虑完井、多相渗流及井筒压降对产能的影响，提出了利用流动阻力、相渗透率及井筒与油藏流动耦合修正水平井产能的修正方法，提高预测公式的适用性，为边底水油藏水平井生产提供了指导作用。

In the context of a system of barotropic shallow-water equations and Boussinesq approximate equations for two-dimensional meso-scale transversal wave disturbance in zonally sheared base flow, study is performed of the physical process of the meso disturbance propagation along the flow, indicating that such vortex Rossby waves are separated into two kinds. The first kind VRW is produced owing to the second-order horizontal shear in the flow or due to the meridional change in vertical vorticity of the flow, i.
