利用试井和生产测井资料估算储层的动态渗透率

Estimation of Dynamic Permeability from Data of Well Test and Production Well Logs.

通常根据岩芯相渗透率试验或试井资料求得储层动态渗透率。针对目标油田取芯少、往往是多层试井的特点,提出利用多层合试的试井资料和生产测井资料估算储层动态渗透率的方法。可估算产油井各产层的油、水相有效渗透率,且能估算注水井各注水层的水相渗透率,这些动态渗透率能更好地反映各小层的动态特征。

Dynamic permeability of the reservoir is usually estimated from phase permeability experiment of core plugs or well test. For the condition of seldom core wells and well testing feature of multiple layers, the method to estimate dynamic permeability of each production zone by using combination of well test and production well log data is suggested. This method can be utilized not only to calculate effective permeability of oil or water phase of each producing oil zone of oil wells, but also to estimate effective permeability of water phase of each absorbing water zone of water wells which can rather reflect the dynamic characters of each zone.
