利用压降数据预测非均质地层渗透率分布

由予国内外存在大量的非均质油藏，利用试井资料及其他动态资料求取地层参数、描述油藏的非均质性，是国内外石油工业界中的一个热点和难点课题，特别是上世纪80年代以后，国外对直接根据不稳定试井资料对储层非均质性进行大量理论探讨。美国的Stanford大学、Tulsa大学、加拿大Alberta大学和Chevron公司等众多研究单位都在对这一课题进行研究，尤其是在预测地层渗透率分布问题上进行了许多尝试。综合运用油气渗流理论、特殊函数、数值计算方法，研究了利用压降数据预测非均质地层渗透率分布的理论和方法。

Prediction on Permeability Distribution of Heterogeneous Reservoir Using Drawdown Data

There are so many heterogeneous reservoirs at home and abroad that it is the hotspot and difficult problem to calculate the formation parameters and describe the heterogeneity of reservoir using the well test data and other dynamic data.Especially after 1980s,many theoretic researches have been done to use transient testing data to describe the reservoir heterogeneity.Numerous research institutes,such as Stanford U, Tulsa U ,Alberta U and Chevron Corp are doing some studies about this problem,particularly in the area of predicting the permeability distribution of the formation.Based on the domestic and foreign literatures,this paper synthesizes many theories,such as Oil and Gas Flowing Theory,Special Function and Numerical Simulation.The methods and theories about predicting the reservoir permeability distribution are also discussed.
