摘要：有机质成熟度是评价烃源岩和油气演化的地球化学参数之一，沉积岩中镜质体反射率的分析测定对于油气发现具有重要意义。中国下古生界海相烃源岩地层有机质丰度低，演化程度高，缺乏典型的镜质体，因而常规的海相有机地球化学演化指标不适用。应用海相烃源岩镜状体反射率分析测定方法实验，然后将测定结果换算为等效的镜质体反射率，从而标定出海相烃源岩的有机质成熟度。应用此方法对塔里木盆地满加尔地区中下

Abstract : The maturity of the organic matter is one of the most important geochemical parameters for the evaluation of the hydrocarbon-source rocks and hydrocarbon evolution, the analysis and measurement of the vitrinite reflec-tance in the sedimentary rocks possess greatly significance for the discovery of the oil and gas, For China Paleozoic marine hydrocarbon-source rocks, due to the low organic matter abundance, high evolution degree and lack of typi-cal vitrinite, the conventional evaluating indexes of the marine organic geochemistry do not adapt. With the help of the test of the analyzing and measuring method of the vitrinite-like maceral reflectance of the marine hydrocarbon-source rocks, the achieved results were converted into the equivalent vitrinite reflectance, thus the organic matter maturity of the rocks could be calibrated. The method was applied in the evaluation of medium and lower Ordovi-cian-Cambrian hydrocarbon source rocks in Manjiaer area of Tarim Basin, and furthermore the maturity histories of the hydrocarbon source rocks in Gucheng area and East Tarim Uplift have been restored.
