前言生油岩评价常用的工艺包括总有机碳(TOC)测定、岩石-热解分析、有机岩相学以及各种有机地球化学分析.其中有些分析方法价格昂贵.为了降低分析费用,在详细分析时,需要对样品进行仔细选择.因此要用一种快速筛选分析指导这种选择.Welte(1981)等人提出的三种筛选方法包括 TOC 测定、IRUS 和岩石—热解分析.TOC 和IRUS(根据红外分析计算饱和烃当量)主要给出生油岩有机质数量方面的资料.另一方面,岩石-热解分析可以提供关于生油岩性质(HI)和热成熟度(Tmax)两方面的资
Preface The commonly used processes for the evaluation of source rocks include total organic carbon (TOC) determination, rock-pyrolysis analysis, organic petrography and various organic geochemical analyzes, some of which are expensive. In order to reduce analysis costs, , A careful selection of samples is required, so a quick screening assay is used to guide this selection.The three screening methods proposed by Welte (1981) and others include TOC determination, IRUS and rock-pyrolysis analysis.TOC and IRUS ( Based on the infrared analysis of saturated hydrocarbon equivalents), data on the amount of organic matter in the source rocks are mainly given. On the other hand, rock-pyrolysis analysis can provide information on both the source rock properties (HI) and the thermal maturity (Tmax)
