摘　　要：台西盆地具有白垩系-古新统、始新统和上渐新统-中新统三大套油气源岩,其有机质丰度属中等-较好;有机质属Ⅱ_B-Ⅲ型干酪根,生油门限深度分别为3000m、2400m和1400-2400m。盆内含油气层位多,储集性能及盖层条件良好,有三大类构造圈闭。作者估算该盆地海域内的油气资源量为12.8×10~8t,并划分出三级含油气远景区。The writer, having collected and analysed the petroleum geological data available in West Taiwan Basin, suggests that there are three units of source rocks (K-E_1,E_2 and E_3~2-N_1) ,a higher content of or- ganic matter, type Ⅱ_B-Ⅲ kerogen. Their relevant hydrocarbon generating threshold depth might be 3000m,2400m and 1400-2400m respectirely and there are good researvoir and cap rocks, many large structural traps. Based upon these excellent conditions, he estimates that the resource extent of petroleum may be totaled 12. 8×10~8tohs in the basin and he further divide the basin into three classes of hydro- carbon-bearing potential areas.
