油藏描述中求取特低渗储层渗透率的方法

AN APPROACH TO THE PERMEABILITY EVALUATION OF AN ULTRA-LOW RESERVOIR IN RESERVOIR DESCRIPTION

精确求解地层渗透率是历代测井地质解释家十分棘手的问题。以前只是针对非特低渗储层作了大量的工作。本文针对辽河油田陈家洼陷南部浊积成因特低渗储层的渗透率进行研究，提出了一种建立其解释模型的有效方法，并在现场得到比较成功的应用，获得满意的效果。同时为当今测井研究前沿理论─—非线性与非均质测井理论￣［１］提供了有力证据。

How to obtain the accurate permeability value of a reservoir has been a bothering prob-lem to well-log interpreters for years.Previous workwere only focused at reservoirs withnon ordinary-permeability.A research has been carried out in reservoirs with ultra-low-per-meability in south of Chenjia depression,Liaohe oil field.This article presents an effective ap-proach of constructive interpretation models,which have been widely used in this field,andsatisfactory results have been achieved.Meanwhile,this research provides a convincibleproof for the theory to be developed″Non-Linear and Heterogeneous Well-Log Theory″upto date.
