回顾了近年来成烃和成藏地球化学的一些进展,包括:生物标记化合物、正构烷和异构烷的碳数分布、碳同位素分布等生源识别技术;烃源岩是煤层还是煤系泥岩、是碳酸盐岩还是碳酸盐岩层系中的泥岩、琥珀在中东油田中的出现及其意义;应用多组分荧光变化技术和芳烃环数分布技术识别有机质成熟度;应用加氢催化热解方法提取沥青和焦沥青中的生源信息;在封闭系统中的深部地层成烃条件;中国元古界、特别是鄂尔多斯盆地元古界的成烃远景;成烃热模拟实验技术的新思路;判断油气运移聚集的时间及其温度压力条件的技术;未熟低熟油可能先运移后成油的机制;油气运移聚集的模拟实验研究;油气运移的前移标记物和滞后标记物;以及地表地球化学勘探的难点技术,即提高信噪比和复原被扭曲投影的技术。
Some advances in geochemistry of hydrocarbon generation and accumulation in recent years are reviewed, including biomarker compounds, carbon number distribution of n-alkanes and isoparaffins, and identification of carbon isotopes; source rock is coal seam or coal-series mudstone , Is the appearance and significance of mudstone and amber in carbonate or carbonate rock system in the Middle East oil field; the maturity of organic matter is identified by multicomponent fluorescence change technology and aromatic ring number distribution technology; the application of hydrogenation catalytic heat Solution method to extract biogenic information in bitumen and tar pitch; deep formation hydrocarbon formation conditions in a closed system; hydrocarbon generation prospects of the Chinese Proterozoic, especially in the Proterozoic Ordos Basin; new ideas for hydrocarbon simulation experiments; The technology of judging the time of hydrocarbon migration and accumulation and its temperature and pressure conditions; the mechanism of unripe low-mature oil may migrate first to form oil; the simulation experimental study of migration and accumulation of oil and gas; the forward marker and lag marker of hydrocarbon migration ; And the difficult technologies of surface geochemical exploration, namely, techniques to improve signal-to-noise ratio and recover distorted projections.
