摘　　要：致密砂岩储层由于孔隙结构复杂和强烈的非均质性,气水识别比较困难。本文基于阵列声波测井或是交叉偶极声波测井得到的纵横波速度和密度测井得到的地层密度数据,通过适当的组合构建多种流体因子来识别致密砂岩储层的流体性质。在实际井中应用,这些因子指示流体的性质与试气结论是一致的。表明用这些因子来识别流体是有效的。due to the complex pore structure and strong heterogeneity of tight sandstone reservoir, it is difficult to identify gas and water.This paper based on P-wave and S-wave velocity from array acoustic logging or cross dipole acoustic logging and formation density data from density logging, to identify the fluid properties of tight sandstone reservoir through the appropriate combination of multiple fluid factor construction. In practical applications, these factors indicate that the properties of the fluid are consistent with the test results. It is shown that these factors are effective in identifying fluids.
