Geochemical Characteristics of Carboniferous Source Rocks in the Jimunai Basin and the Tacheng Basin of Northwest Xinjiang
新疆北部吉木乃盆地与塔城盆地石炭系烃源岩特征

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.
