摘要
This paper presents the effects of the secondary outgrowth pattern and the replacement intensity on the reservoir petrophysical property. The study shows that the deep strata in Wunan-Lücaotan area are of developed quartz secondary outgrowth, where the reservoir property is poor; while the replacement of calcite, dolomite and anhydrite reaches strong or extremely strong, the property becomes poor obviously. com:office:office" />
