| 摘 要： | 云南保山盆地上第三系为高孔隙度中低渗透率含气砂岩储层特征,其特点是电性特征受岩性影响大和高孔隙度中低渗透率.针对性地建立合理的岩石体积模型,采用非电法-库克法计算储层的孔隙度和饱和度;在渗透率的计算上充分结合该区储层特征,引入泥质含量、粒径大小、孔喉结构等影响因素.最终的计算结果与岩心分析数据及试气结论较吻合.

| Abstract: | Neogene gas sandstone reservoirs in Baoshan Basin of Yunnan are characteristic of great various lithologies, high shale content, high porosity, middle-low permeability and electric characters deeply influenced by lithology. Neutron-density crossplot method is used to calculate porosities and saturations of the reservoirs. After correctly selecting local characteristic parame- ters of the reservoir, such as shale content, grain diameter, pore throat, etc. , Zeng Wenchonges permeability interpretation model is used to calculate permeabilities. The calculation effectiveness is rather good. |
