Performance Analysis of Transient Pressure in Low Permeability Reservoir

Abstract

Abstract: The unsteady flow in low permeability reservoir is a non-linear problem with dynamic boundary, so it is extremely complex to find exact solution. In order to simplify the calculation, an approximate equation for reservoir pressure distribution is used to study the transient pressure distribution characteristics followed by obtaining the movement rule of dynamic boundary using material balance principle. Finally, the varied bottom-hole pressure is calculated.

Key words: low permeability reservoir, pressure gradient, dynamic boundary, unsteady flow
