新疆北部吉木乃盆地与塔城盆地石炭系烃源岩特征

通过对新疆西北部吉参1井及塔参1井石炭系烃源岩样品有机地球化学特征进行分析，明确研究区石炭系烃源岩生气潜力。吉参1井石炭系烃源岩主要以炭质泥岩为主，塔参1井石炭系烃源岩主要为暗色泥岩。吉参1井及塔参1井泥质烃源岩有机质丰度较高，都达到好烃源岩的标准。有机质类型以Ⅲ型为主，热演化均达到高成熟阶段，具有良好的天然气生成能力。

Geochemical Characteristics of Carboniferous Source Rocks in the Jimunai Basin and the Tacheng Basin of Northwest Xinjiang

Organic geochemistry measurements and analyses were conducted on Carboniferous source rock samples from well Jican-1 and well Tacan-1.The results indicated that Carboniferous source rock in well Jican-1 predominantly consists of carbonaceous mudstones and that in well Tacan-1 predominantly consists of dark-colored mudstones.Both of the Carboniferous carbonaceous mudstones in well Jican-1 and dark mudstones in well Tacan-1 contain high abundance of organic matter,and are evaluated as good source rocks.Organic matters are mainly type III kerogens in the Carboniferous samples of well Jican-1 and well Tacan1,and have been at the high-mature stage with large gas source potential.
