摘要
储岩热解分析是一项简便、快速、有效的地球化学录井技术，可用于石油勘探的油层检测和油气藏早期评价。热解含油率反映储岩的含油性，可半定量地确定油层级别；根据油藏剖面的热解参数变化，能进行油藏非均质性描述，确定油水界面；利用热解含油率作为油层产能预测模型的计算参数，结合其它分析资料，可在试油之前预测油层产能；热解指标（Ｓ０＋Ｓ１′）／Ｐｇ表征油层原油的油质，能用于预测井下原油的密度。
The pyrolysis analysis of reservoir rock is a simple, convenient, rapid and effective geochemistry log technique, which can be applied to monitor and evaluate reservoir primarily in petroleum exploration. The pyrolysis parameter (Pg), as a reflection of the oil saturation of reservoir rock, can grade the reservoir semiquantitatively. Based on the variation of the pyrolysis parameters in reservoir section, it is possible to describle heterogeneity and define oil-water contact in a reservoir. According to predicting model of reservoir production, the pyrolysis saturation (Pg), combined with other analysis data, can predict reservoir production before drill stem test. The pyrolysis parameter (S0+S'1 )/Pg which reflects reservoir oil nature can be used to predict subsurface oil density.
