Abstract

According to the macro-observation of the outcrop sections and drilling core of Leikoupo formation of Middle Triassic in northwest Sichuan basin,and the analysis of such supporting materials as thin-section,cathode luminescence,electron microprobe and mineral inclosure,the author makes a comparatively deep study of the structure,characteristics and composition forms of the cement in the sparry grain dolomite and the blue green algae agglutinate dolomite of the Leikoupo formation reservoir.

Key words： Leikoupo formation; Reservoir; Primary porosity; Cement; Composition forms.
