 　 油水相对渗透率是评价油藏的一个重要指标,它在油藏工程计算中的应用十分广泛。通常油水相对渗透率可用稳态和非稳态两种方法求得。文中提出了几种非稳态法计算油水相对渗透率,既考虑了日常用恒速法,又提出了非恒速非恒压数学处理方法,非稳态法获取的数据较为可靠,但数学处理难度较大。笔者编制了相应的实用软件,其适用范围广,经多次应用实践,效果良好。

The oil-water relative permeability is an important index
of app raising oil reservoir, It is very extensive that uses in the
calculation of oil reservoir engineering. The oil-water relative
permeability generally get by steady-state method and
unsteady-state method. Have put forward several kinds of
mathematical methods to calculate oil-water relative
permeability, Having not only use the constant-speed method
also p roposed unconstant-speed method and unconstant-
p ressure method, Work out the suitable software.
