摘要
镜质组反射率的抑制常发生在以下情况 :1高含量的壳质组和 (或 )腐泥组 ;2厌氧、还原的沉积环境 ;3特定的古植物群落 ;4特定的岩性。介绍了产生镜质组反射率抑制的机制及识别抑制的方法 ,比较了采用镜质组化学组成法、镜质组反射率和荧光相结合方法 (VRF)、氢指数— Ro图版法、多显微组分荧光变化方法 (FAMM)
In petroleum exploration the suppression of vitrinite reflectance is a major problem which mislead the geologist to underestimate the real maturity of the source rocks.The suppression may result from:①high exitinite and/or sapropelinite contents;②anaerobic environment;③particular paleo flors;④and paticular lithotype.Its mechanism of the methods for its identification are introduced,and the advantages and disadvantages of some correction methods such as vitrinite chemistry,VRF(a technique combining vitrinite reflectance and fluorescence), I o(H) R o diagram and FAMM(fluorescence alteration of multiple macerals) are discussed.
