摘要: 本文根据三维地震资料提取了TZ地区各井井区20种地震参数,然后采用费歇二类差别分析,分别建立了油气井与干井的判别函数,并根据判别临界值对欧8井B油气层的分布范围进行了预测.从预测结果看,效果较好.

Abstract: This paper collects 20 types of seismic parameters of the wells in the field Tz from the 3D deismogram, and establishes the discriminant function of oil-gas well and dry well by Fisher type-Two discriminant analysis. This paper also predicts the distribution scope of Well 08 hydrocarbon Zone B by discriminant critical value, and judging from the results, the prediction is quite satisfactory.
