摘　　要：低渗透储层喉道特征是决定储层物性好差的关键因素.为了解大庆布木格地区低渗透扶杨油层特点和渗流特征,利用恒速压汞技术对该区扶杨油层孔隙特征进行了研究.结果表明,该地区渗透率低的主要原因是储层孔隙结构中喉道半径过于细小所致.因此该地区整体投入有效开发难度较大.The throat characteristic of the low permeability reservoir is the crucial factor that decides if physical quality is good in low permeability layer. The porosity characteristic low permeability of FY oil-layer in Bu-muge area is studied by means of rate controlled mercury penetration method, its result indicates that the crucial origin of low permeability is that the throat radius of porosity configuration in the layer is too small, and therefore it is difficult to have the oil-layer of the area highly effectively developed.
