Analytical solution of flow in infinite stratified oil reservoir and its application

This paper presents an analytical solution for the production function and pressure distribution function of flow in infinite stratified oil reservoir with crosflow under the condition of constant wellbore pressure (CWP condition) by Weber’s integral transformation.The calculation results are shown in the form of curves and these results can be used to analyse unsteady flow test of production with CWP condition.     

非线性周期波及破碎波对杆件的作用力

本文采用十五阶 Stokes 波的 Pade 逼近,获得了与实验较为一致的流场,并且利用已有的破碎波的速度、加速度场,计算了非线性波和破碎波对各种杆件作用力,比较了它们的主要特征,为海洋工程设计提供依据。
