| 摘 要： | 根据研究区测井资料的统计分析,砂泥岩纵波波阻抗叠置,利用常规波阻抗反演方法无法有效区分岩性。文章在对研究区测井资料统计的基础上,应用Jason软件算出研究区砂泥岩的波阻抗之后,利用测井统计出的波阻抗与岩性的拟合关系,应用Strata软件剔除泥岩,生成砂岩数据体;再利用测井统计出的砂岩波阻抗与孔隙度的拟合关系,把砂岩波阻抗数据体换算成孔隙度数据体,从而达到储层预测的目的。 |
| 关 键 词： | 储层预测 岩性 波阻抗 孔隙度 |

| Abstract: | According to the statistical analysis of log data in the research area,the P-wave impedance of the sand and shale is overlaying,so the lithology can not be distinguished by the conventional impedance inversion method.In this paper,on the basis of the logging data,the JASON Software is used to calculate the sand and shale impedance in the area.Then making use of the fitting relationships between impedance and lithology,and next using the STRATA Software to remove the mudstone,the sandstone data are obtained in this way.Furthermore,still making use of the fitting relationship between sandstone impedance and porosity,change the sandstone impedance data into porosity data.Finally,the aim of the reservoir prediction is achieved. |
| Keywords: | reservoir prediction lithology impedance porosity |
