Description

一种离心式连续取气样烃源岩生烃热模拟实验装置 技术领域
本发明涉及一种离心式连续取气样烃源岩生烃热模拟实验装置。
背景技术
利用热模拟实验方法对烃源岩进行热解产生油气，是评价烃源岩生气量的重要手段之一。热模拟过程中，需要把产生的油及时移出加热区从而避免油的二次裂解。
当前热模拟产生天然气的实验主要利用黄金管作为反应容器，即把样品放置在黄金管中，通过加热产生气体。黄金管局限封闭的生烃环境与自然界的生烃环境有较大的区别，在自然界的地层中，地热作用产生的油，可以通过岩石裂隙运移作用离开加热区域，从而避免或减弱油裂解生气效应；但因为黄金管是一个封闭的局限体系，热模拟产生的油无法及时排出，在较高的温度下，油发生裂解产生气体，导致气体生成量明显高于地层中气体的生成量。另一种热模拟实验方法是利用流动的载气把生成的油吹出，但是这种方法在实践中应用效果不佳，因为载气的流量过大将使得天然气被稀释，导致下一步的分析困难；如果载气流量过小则不能有效的把油吹出加热区。除了上述原因，在热模拟生气实验中，还需要分段收集烃源岩在不同温度阶段产生的气体，从而为生烃动力学提供数据。到目前为止，市场上没有能满足以上要求的实验仪器。
