%X 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, and analyzes the diagenetic environment and the reservoir space. The six different types of the sparry cement in the protosomatic intergranular hole and the algae agglutinate ramework bore are the outcome of different the diagenetic environmen of four periods, and they vary greatly in the characteristics and composition form of the attitude, mineralogy, geochemistry and others, and as well, in their influence on the reservoir space.
