摘　　要：以岩石薄片、扫描电镜、物性、毛管压力曲线等分析资料及测井解释结果,从沉积特征、储层展布、物性特征、岩性特征、孔隙类型及孔隙结构、主控因素等方面对贝中次凹南屯组一段储层进行了综合评价,认为该储层为一套低孔特低渗储层,其物性主要受沉积微相及成岩作用控制,主要发育于研究区的西部和中南部地区。综合储层的岩性、物性、成岩后生作用和孔隙结构等特征,参考松辽盆地储集层分类标准,对贝中次凹南屯组一段储层进行了分类,将其划分为Ⅰ(好)、Ⅱ(中等)、Ⅲ(差)、Ⅳ(极差)4大类,区内主要发育Ⅱ类储层,少量Ⅰ类储层。Based on the rock section,SEM,physical property,lithologic features,capillary pressure curve and the result of well log interpretation,the sedimentary characteristics,reservoir distribution,its physical property,pore type,pore structure,and the master control factors of the reservoir were comprehensively evaluated.It was considered that the reservoir was a low-porosity and ultra-low permeability one,the physical property of it was controlled by sedimentary facies and diagenesis.Most of the reservoirs were developed in the west and mid-south of Beizhong sub-depression.Based on the above analysis,the reservoirs were divided into four types,type Ⅰ,Ⅱ,Ⅱ,Ⅳand most of the reservoirs are type Ⅱ in this area,the next is typeⅠ.
