苏南西部石炭系碳酸盐岩成岩演化与储集特征

Reservoir characteristics and diagenetic evolution of the carbonatite of Carboniferous System in the west part of Sunan area

苏南西部地区石炭系广泛发育有一套多滩(岛)浅陆表海(台地)潮上带至潮下带沉积的碳酸盐岩,层位齐全。根据岩石的沉积特征,划分为十种岩相。结合岩石成岩作用探讨了孔隙演化,并在现今储集特征分析的基础上,进行了潜在储层预测。

In the west part of Sunan area, there was a well developed stratum of carbonatite of Carboniferous System, which was the deposition of the supralittoral and subtidal zones in the muhi - beach （island） Epicontinental Sea （ plat- form） ,and the formations were complete. On the basis of the sedimentary characteristic of the rock,the lithofacies were classified into 10 kinds. The diagenesis was utilized to analyze the evolution of pore. And based on the research of the res- ervoir characteristic, the potential reservoir of carbonatite was forecasted.
