| 摘 要： | 柴达木盆地北缘(以下简称柴北缘)石炭系烃源岩主要发育在上石炭统克鲁克组,其暗色碳酸盐岩达到了烃源岩评价标准,泥岩为较好―好的烃源岩,煤为较差的烃源岩。考虑到演化作用与风化作用的影响,推测柴北缘石炭系碳酸盐岩和泥岩均达到了好烃源岩评价标准,其有机质演化处在成熟―高成熟阶段。认为该地区石炭系具有良好的油气勘探前景。

| Abstract: | Hydrocarbon source rock of carboniferous is mainly developed in Keluke formation of upper carboniferous, its carbonate attain evalution standard of source rock, mudstone is middle-good source rock, and coal is poor source rock. Thinking over the influences of evolution and weathering, the results that carbonate and mudstone is good hydrocarbon source rock is conjectured in the northern margin of Chaidamu basin, and its organic matter is in evolution stage of maturation-high maturation. The analytical data show that carboniferous possesses better oil and gas exploration prespects. |
