-
摘要: 由中国石油勘探开发研究院廊坊分院建立的全岩热模拟仪器分析方法是采用岩心样品(岩石颗粒0.5～2 mm)来模拟烃类生成的一项实验新技术.该方法模拟结果表明:(1)不同类型样品单位质量岩石的产气率与传统的加水温压模拟法结果具有可比性;(2)能够反映源岩在不同演化阶段的产气量;(3)比常规的有机碳评价方法能更准确地反映源岩在不同演化阶段的产气潜力.(4)全岩热模拟新方法经济、简便、分析周期短,可以用于大量常规样品分析,是判识有效气源岩及定量评价的一种快速、可靠的方法,在油气勘探过程中,将对烃源岩的评价发挥重要作用。Abstract: The pyrolysis on-line gas chromatographic method of rock simulation,developed by Langf ang Branch of Research institute of Petroleum Exploration and Development,is a novel laboratory techniCue used to simulate hydrocarbon formation,which employs the unconventional grain size(0.5 ~2mm）. The results detected from the novel method of pyrolysis rock chips show that (1)The pyrolysate yields of unit Cuality rock of different samples are similar to that of conventional hydrous closed-system， so the t wo methods are comparable.(2)Rock pyrolysis experiment can reflect the yields of gas generated fromits host rock in different evolution stage. (3)The novel method is more valid in the potential evaluation of gas generation compared to that of conventional organic carbon in different evolution stage.(4)Anumber of conventional samples can be tested in rock pyrolysis experiment for its economical and simple method and the analytical cycle is short, so it is an available and credi ble techniCue for the judgement of validity and the Cuantitative evaluation of source rock. This technique will play more important role in the evaluation of source rock during the exploration of petroleum.
