摘　　要：利用恒速压汞和核磁共振技术,结合岩石薄片和铸体薄片观察、扫描电镜、常规压汞等分析测试手段,充分考虑储层孔隙结构和可动流体因素,引入孔隙结构类型、平均喉道半径、平均孔喉半径比、可动流体饱和度以及核磁孔隙度、核磁渗透率等新参数,建立储层综合评价标准,将塔中顺托果勒地区柯坪塔格组下段储层划分为3种类型,研究了其分布特征,结果表明,发育于潮汐水道微相中的Ⅰ类储层是今后勘探开发主要目标。With advanced constant- rate mercury penetration and NMR technologies,and combing with observation of rock section and cast section,SEM,conventional mercury penetration and other testing approaches,the pore structure and movable fluids in reservoir are considered. Then,together with some new parameters,such as structural type of pore,average throat radius,average pore /throat radius ratio,saturation of movable fluid,NMR porosity and NMR permeability,comprehensive evaluation standards are established. On this basis,the reservoir of lower member of Kepingtage Formation of Shuntuoguole Region in Tazhong is divided into3 types,whose distribution is studied. The results suggest Type- I reservoir developed in micro- facies of tidal water channel as the major target for future exploration and development.
