Abstract：Through Paleozoic cores description and microscope observation in Zhuanghai area, the paper discussed the feature of buried modification, built up recognition sign of buried modification. The organic and inorganic gas-liquid bi-phase inclusions with bright orange-yellow luminescent in carbonate cavern generally are intergrowth. Homogenization temperature of inclusion is from 901 to 150℃,with bi-pick mode. The staple isotope data show that the mean value of δ13C is from -2. 2 to -3. 5, the mean value of δ18O is from -17. 4to -13. 2. In comparison with isotopic data of infill in Caledonian and Indosinian fractures, the carbon-isotopic data infill of buried cavern is characteristic migrating toward higher data and oxygen-isotopic value toward lower data. Homogenization temperature of aqueous inclusion and table isotopic data also sustain the function of late buried modification. The paper analyzed the development character of Paleozoic reserve space at the well Zhuanggu-10, and believed that residual Majiagou Formation carbonate in well Zhuanggu-10 was significantly affected by later buried modification; a various secondary modification cavity, fissure and bore are major reserve space,the type of which is complex. The formation of complex pore is caused by that the press-dispel-water of giant-thick Tertiary sediments coming from Gubei sag migrated along the boundary fault to highness of Zhuangxi buried hill,acted on Paleozoic carbonate of well Zhuanggu-10 and produced buried modification in buried condition.
