摘　　要：确定油层物性下限(CUT OFF)值是储集层评价和储量评估的基础。砂岩和碳酸盐岩油层物性下限研究比较多,也比较成熟。对于砂砾岩储层,由于埋藏深度较深,孔隙结构多为双模态或复模态结构,砂砾岩油层物性下限研究比较难。通过常规物性下限研究方法结合核磁共振测井方法,确定了砂砾岩储层物性下限(CUT OFF)值为孔隙度大于等于6%,渗透率大于等于85×10-3um2。Determination of the lower limit value(CUT OFF) of a reservoir is the foundation of reserves evaluation.The lower limit of physical property of sandstone and carbonate reservoirs is studied better.It is mature.For glutenite reservoirs,owing to deep burial,multi-structure pore(bimodal or complex mode structure),it is difficult to study the physical property of a glutenite reservoir.Combining conventional physical property lower limit research with nuclear magnetic resonance logging,the lower limit value of a glutenite reservoir is determined as follow:the porosity is more than or equal to 6 %;the permeability is more than or equal to 0.85×10-3 um2.
