4.A linearized pressure viscosity equation is presented together with Reynolds equation in dynamic condition for infinitely short journal bearings, the analytical solutions of pressure and force components in oil film is obtained by using the method of Fourier sine transforms.
7.A pressure draw-down equation is first established for partial penetration gas well in Darcy-flow dominated domain in bottom water reservoir, and then a binomial deliverability equation is obtained by combining with Non-Darcy binomial radial flow equation.
