用CT扫描技术观察油层岩心的孔隙结构

VISUALIZATION OF PORE STRUCTURES IN ROCKS WITH COMPUTERIZED TOMOGRAPHY OF X-RAYS

用CT扫描技术观测油层岩心孔隙结构,是一种快速有效的测试方法。它证明,常规渗透率测试所得K值偏低。文章还简要地介绍了CT扫描技术的基本原理及其现状。

The basic principles and the up-to-date situation of CT Scan are briefly introduced here. The CT Scan has proved to be a rapid and useful method for observing pore structures in rocks. Moreover, it has been shown that the permeability measured by conventional methods is a little lower than the real one.
