摘要

本文着重讨论了岩石样品的扫描电镜不镀膜定位观察技术及其使用方法.利用这种方法,在油层改造及酸化机理研究中取得了新的认识——酸化最敏感矿物为长石而不是粘土.

Abstract

In the paper,technique of uncoated rock samples and its operations for the SEM measurement are discussed.By this technique,a new understanding is obtained from studies on secondary reworks of oil beds and acidization mechanism,from which the most sensitive mineral for acidization is feldspar rather than clay.
