2、爾盆地上三疊統(tǒng)暗色泥巖有機(jī)碳含量的預(yù)測模型,并估算了主要探井上三疊統(tǒng)暗色泥巖的有機(jī)碳含量。綜合預(yù)測和實(shí)測有機(jī)碳含量平面分布特征發(fā)現(xiàn),上三疊統(tǒng)有機(jī)碳含量顯示有4個相對高值區(qū),分別位于烏倫古坳陷的索索泉凹陷、中央坳陷帶的阜康凹陷、盆1井西凹陷和瑪湖凹陷,以索素泉凹陷有機(jī)碳含量最高,阜康凹陷和盆1井西凹陷其次,瑪湖凹陷總體較低。有機(jī)碳含量表明上三疊統(tǒng)為一套中等一較好的烴源巖。關(guān)鍵詞:上三疊統(tǒng);暗色泥巖;有機(jī)碳含量;準(zhǔn)噶爾盆地中圖分類號:P618.13文獻(xiàn)標(biāo)識碼:A文章編號:1006—7493(2012)04—0745—06O曙阻PredictionMethoda
