摘要:  简述长岩芯实验确定油层污染关系的基本原理和基本实验过程,分析长岩芯实验确定地
层侵入深度和污染深度的方法,并通过实验数据分析指出:地层侵入深度大于污染深度,泥浆颗粒对地层造成的损害大于泥浆滤液对地层的损害。

Abstract: This paper briefly introduces the basic principle and experimental procedure of the determination of oil-bearing formation damage by long core experiment, analyzes the method of the determination of formation invasion and damage depth by the long core experiment, and points out, through the analysis of the experimental data, that the invasion depth of mud filtrate is greater than the damage depth of mud filtrate in formation, and that the damage of filtrate to formatin is less than that of mud particles.

Key words: Core, Experiment, Damage, Formation
