摘要

摘要: 烃源岩生烃过程受温度、压力等地质条件的影响,这一过程可以通过化学动力学方法来描述。通过2种模拟实验方法,即开放体系和封闭体系,研究了渤海湾盆地济阳坳陷不同沉积环境的4套主力烃源岩的生烃动力学特征。封闭体系模拟实验中设计了与地下相同的垂向等效压力条件。通过对比分析认为,压力对烃源岩的生烃过程具有不同程度的抑制作用,主要表现在对不同类型的烃源岩及在不同的演化阶段其影响均有所不同;随母质生烃潜力的增大,以及在演化程度增大、地层压力增高的情况下,生烃抑制作用越明显。根据实验结果,确定了4套烃源岩各演化阶段有压力条件存在的生烃动力学参数。

Abstract: Hydrocarbon generation is influenced by geologic settings such as temperature,pressure and so on.The process can be described in chemical kinetic models.Open-system and closed-system simulation experiments were used to study the kinetic characteristics of 4 kinds of main source rocks in the Ji-yang Depression,the Bohai Bay Basin.Vertical pressures equivalent to underground strata were taken into account in closed-system experiments.Some conclusions were made on the basis of the comparative analysis of the experiments.Pressure suppressed the hydrocarbon generation on different extents according to different source rocks and different evolutionary stages.With increase of the hydrocarbon generation potential of mother materials,the evolutionary degree or formation pressure,it was showed more suppression of hydrocarbon generation.The kinetic parameters of hydrocarbon generation of the source rocks related to different pressures were accordingly determined.
