摘要: 突泉盆地南部的牤牛海凹陷实施的突D1井见到良好的油气发现.钻井烃源岩的地化指标表明：有机质丰度低；有机质类型主要为Ⅲ型，少部分为Ⅱ型；有机质演化进入高成熟阶段，处于生气阶段.指示突D1井中侏罗统万宝组烃源岩具有一定的生烃条件.突泉盆地油气勘探方向应以找气为主.

Abstract: The TD1 well in the Mangniuhai depression in Tuquan Basin shows good?oil occurrence. Geochemical analysis for some drill hole cores indicates that the organic matter is in low abundance, mainly belonging to Type III, with minus Type II, in high mature stage. All these characteristics suggest that the source rocks of Middle Jurassic Wanbao Formation has good hydrocarbon-generating conditions. The exploration in the Tuquan Basin should focus on natural gas.
