摘要: 本文对含有Ⅰ类干酪根的扶16-02井(埋深355.9m)的未成熟生油岩样品进行了一系列人工熟化,得到了具有不同成熟度的样品。对这些熟化样品,用Ⅱ型岩石评价仪(Rock-EvalⅡ)进行了热解常规分析,用Ⅰ型岩石评价仪(Rock-EvalⅠ)进行了热解模拟实验,并用热解气相色谱仪进行了热解产物组成分析。对于热解模拟实验数据,按串联一级反应动力学模型(Friedman方法)进行处理,得到了一系列热解分析指标和热解生烃动力学参数,揭示了热解产物组成随生油岩成熟度变化的规律以及演化过程中干酪根结构和热解反应本质的变化。

Abstract: To study the pyrolysis kinetic characteristics of hydrocarbon formation and the change of composition of pyrolysis products in the thermal evolution process of type Ⅰ source rock, in this paper unmatured source rock sample of well Fu 16-02 (depth of burial 355.9m)with type Ⅰ kerogen is artificially matured at different temperatures.For those matured samples, pyrolysis analysis is carried out with Rock-Eval type Ⅱ device,composition of pyrolysis product was analyzed with pyrolysis gas chromatography, and pyrolysis simulated experiment has been carried out with Rock-Eval type Ⅰ device.The data from pyrolysis simulated experiments are treated by using first order reaction kinetic model.A series of pyrolysis analytical indices, kinetic parameters of the hydrocarbon formation and characteristics of change of pyrolysis product composition with the maturity of source rock are obtained, and the changes of structure of kerogen and the nature of pyrolysis reaction are discussed.
