摘　　要：研究区位于曾母盆地西部,以高地温梯度为主,有机质成熟度高,发育上始新统—上新统烃源岩,其中中、上中新统为两套最重要的烃源层。有机质丰度为低—中等,属Ⅱ_8—Ⅲ型干酪根;具有良好的储集性能、盖层条件及圈闭条件;该区以产天然气为主,具有较好的油气前景。Upper Eocene to Pliocene contained Ⅱ_B—Ⅲ type kerogene are in the west part of Zengmu Basin. Middle Miocene to Upper Miocene may be two important suites of oil and gas-bearing rocks. The earth temperature gradient is so high that the organic material is very mature. There are good reservoirs, caprocks and excellent traps in the region. And the petroleum prospection will be very good with gas being the main resource.
