南祁连盆地三叠系烃源岩有机地球化学特征
Organic Geochemistry of Triassic Source Rocks in the Southern Qilian Basin
摘要
Abstract
According to the outdoor profile survey, collection of samples in systematic and the organic geochemical analysis technique including rock pyrolysis, residual organic carbon content, kerogen analysis, organic maceral, vitrinite reflectance, gas chromatography of saturated hydrocarbon and transmitted light microscopy, the authors discussed organic matter abundance, type and maturity of Tag carbonate and TEd mudstone outcrop samples in the Southern Qilian Basin, the original sedimentary environment and bio-inputs of organic matter. The results show that Tag carbonate belong to good source rocks, the organic matter is type ~ -II and TEd mudstone is type II -III. The organic matter has a high degree of thermal evolution and is at the high and over mature stage. They are deposited in transitional and mainly terrestrial facies. Organic matters are mainly derived from aquatic plant and errestrial life biodegradation.关键词
