摘要
烃源岩的热压模拟是探索油气生成机制、重现成油过程的重要实验手段之一。为了进一步评价各类源岩的产烃潜力,本文通过对各类煤岩及煤系泥岩、非煤系湖相泥岩和海相碳酸盐岩的热压模拟,获得了各类源岩的气、液态烃产率曲线及不同演化阶段的气、液态烃产率,为各类源岩油气生成潜力的定量评价、总油气生成量的计算及资源预测提供了重要参数和科学依据。为了进一步扩大源岩热压模拟的实际应用,本文提出了利用源岩热压模拟气、液态烃产率曲线及不同演化阶段气、液态烃产率,按演化阶段分别计算油、气总生成量的计算方法,解决了长期以来油气合量计算的技术难题,经试用效果良好。
Thermal pressure modeling of hydrocarbon source rocks is one of the im- portant laboratory technique in the study of mechanism of petroleum gene- ration and reestablishment of the petroleum generation.In order to have a further evaluation of the potential of hydrocarbon generation of different types of source rocks,this paper gives the thermal pressure modeled results of the gaseous and liquid hydrocarbon productivity curve and their productivities at different evolution stage of different types of source rocks,coaliferous rocks, coaliferous mudstones,non-coaliferous lake mudstones and marine carbonates to give a scientific base and important parameters for a quantitative evalua tion of the potential of hydrocarbon generation of the different types of source rocks. In order to have a further generalized application of the thermal pressure modeled results,this paper gives methods to estimate the total hy- drocarbon generalized by means of gaseous and liquid hydrocarbon producti- vity curve and gaseous and liquid hydrocarbon generated at different evolu- tion stages respective]y.Satisfactory results are obtained with these methods.
