摘要： 准噶尔盆地玛北油田具有含油砂组厚度较大、储层与盖层间波阻抗差异大、构造简单等有利地质条件，且测井与三维地震资料质量较好。具备地震储层横向预测的基础。因此利用少量关键井资料通过地质含义标定、振幅提取、逐步拟合、协克里金与反射系数约束、分区间孔隙度转换等步骤，对玛北油田主力油组的孔隙度进行了预测。后续探井资料表明，沿层振幅进行孔隙度预测方法简便，效果较好。

Abstract: Mabei oilfield in Junggar basin is characterized by favourable geological conditions such as thicker oil sand members, great wave impedance difference between reservoir and caprock, simple structure, higher quality of logging and 3-D seismic data, providing with the base for transverse prediction of reservoir.This paper predicted the porosity of major oil layer formation in Mabei oilfield by using few key well data, strati-graphic correlation, picking up of amplitude, matching step by step，restriction of She-crikin and reflection coefficient, conversion of porosity in different intervals, and better result is obtained.
