Abstract: Anew concept of petrophysical facies was brought up in the the study of reservoir geology.This concept is different to the previous studied petrophysics andpetrophysical evaluation.It is defined as comprehensive results of sedimentation,diagenesis and later tectonic action,which ultimately displays the present geometrical property of pore,i.e.pore model.The Eogene Shahejie group of Lengdong-Leijia region in Liaohe depression is taken as an example to illustrate the study of petrophysical facies and its useful effect in production.

Key words: petrographical analysis, sendimentation microfacies, diagenesis, structure of porosity, reservoir description, formation evaluation, Liaohe sag

摘要： 本文提出了储层地质学研究中的新理论──岩石物理相.它不同于前人所研究的岩石物理学或岩石物理评价,将岩石物理相定义为沉积作用、成合作用及后期构造作用的综合效应;它最终表现为储层现今的孔隙几何学特征─-孔隙模型.并以辽河凹陷冷东-雷家地区下第三系沙河街组为例,阐述了岩石物理相的研究及应用效果.
