储层孔隙结构分形分析计算机实现

FRACTAL ANALYSIS OF RESERVOIR PORE TEXTURE ACCOMPLISHED BY COMPUTER

分形技术是一种研究储层孔隙结构的新方法，其计算机实现步骤包括；（１）制作ＳＥＭ图片；（２）ＳＥＭ图片数字化；（３）统计特征体；（４）拟合特征体的概率与计算分形孔隙度。此文阐述了在计算机上实现上述各步骤的原理和技术过程，开发了相应的软件，并在实用中取得了较好的效果。

Fractal technique is a new method of studying reservoir pore texture.The process includes: 1. making of SEM imagines;2.digitizing SEM imagines;3.counting geometrical features as a function of feature size;4.fitting the distribution probability of the feature and caculating fractal porosity.The principle and detailed technical process of the analysis are discussed in this paper,and the relative computer program is also developed. The result of practical use has been proved to be satisfactory.
