| 摘 要： | 泰州组一段上亚段砂岩储层岩石类型主要为长石石英砂岩、长石岩屑砂岩、岩屑质长石砂岩和岩屑石英砂岩;储层孔隙度主要分布在7％～17.4％之间,渗透率主要分布在(0.17～125.1)×10-3μm2之间;储集空间主要类型为粒内溶孔、粒间溶孔和裂缝溶孔;根据物性分析和压汞资料,将泰州组一段上亚段储层划分为Ⅰ～Ⅳ四种类型.基于定量成岩作用的分析,认为压实作用、胶结作用是本区储层物性变差的主要原因,溶蚀作用则大大改善了储层物性. |

| Abstract: | Rock types of upper sub-menber of Tai-1 are Feldspar quartz sandstone,feldspar detritus sandstone, detritus feldspar sandstone and detritus quartz sandstone,porosity distributes range of 7% to 17.4% and permeability distributes 0.17 ×10-3 ~125.1 ×1 0-3 μm 2 Main types of Reservoir space are intragranular and intergranular pores,in a few cases,is fracture type.Upper sub-member of Tai-1 sandstone reservoir is divided into 4 types based on Petrophysical Parameters and mercury injection analysis.Compaction and cementation is the main reason of Petrophysical Parameters becoming poor,dissolution has greatly improve the Petrophysical Parameters. |
