摘要
通过对黔南坳陷和桂中坳陷的地层对比和分析,识别出了8种层序界面标志,共划分两个超(二级)层序SS1和SS2,并讨论了各体系域特征。在层序格架中对研究区内的储集体类型进行了总结,主要包括生物礁(滩)储集体、白云岩储集体和缝洞型储集体等3种类型。对层序格架中储集体的成因类型进行了总结归纳:有利的储集体主要有TST礁滩灰岩储集体、HST礁滩灰岩、白云岩储集体。
Eight sequence boundaries are recognized for the South Guizhou depression and Central Guangxi depression,including two supersequences（second-order sequences） SS1 composed of lowstand systems tract（LST）,transgressive systems tract（TST） and highstand systems tract（HST）,and SS2 composed of transgressive systems tract（TST） and highstand systems tract（HST）.The reservoir rocks within the above-mentioned sequence stratigraphic framework consist of organic reef（bank） reservoirs,dolostone reservoirs and fissure-type reservoirs.The favourable reservoir rocks include the organic reef（bank） limestone reservoirs in the transgressive systems tract,organic reef（bank） limestone reservoirs and dolostone reservoirs in the highstand systems tract.
