Pressure-Transient Analysis of Two-Lagered Fractal Reservoirs

Institute of Porous Flow and Fluid Mechanics, Academia Sinica, Langfang Hebei 065007, P. R. China

摘要: 本文研究了双层分形油藏不定常径向渗流,给出了广义对流扩散方程组在拉氏空间中的通解,得到了考虑和不考虑井筒存储和表皮效应时的不同内边界条件下的解,讨论了在不考虑井储和表皮效应时的解的特征.

Abstract: In this article we discuss nonsteady flow of two-lagered fractal reservoirs, and get the solution of generalized C-D equation in Laplace space and then get the solution under different boundary conditions with considering or not considering wellbore storage and skin effects, and at last we analyse the nature of the solution under not considering wellbore storage and skin effects.
