摘　　要：源岩生烃模拟实验是油气资源评价、油气源对比等方面研究中的重要手段,随着近年来技术的进步,生烃模拟实验方法得到了改进。目前,生烃模拟实验方法按照体系的封闭程度分为开放体系、半开放体系和封闭体系3种,不同的实验体系具有不同的优缺点,可根据不同的研究目的选择不同的模拟实验方法。温度是影响源岩生烃模拟实验的最主要因素,实验过程中实际反应温度测定准确与否主要由实验体系的结构决定。对不同类型源岩样品,开展同一体系、不同温度和不同压力条件下的系统生烃模拟实验,探讨温压条件对源岩生烃过程的影响具有重要的意义。Hydrocarbon generation experiment of organic source rocks is an important technical means in resource assessment and oil and gas source correlation. With technological advances in recent years, the simulation methods of hydrocarbon generation experiment have improved. According to the extent of isolation, hydrocarbon generation experiments could be divided into open system, semi-opened system and closed system. Different systems have different advantages and disadvantages. The accuracy of reaction temperature has a great influence on the application of experiment results. The accuracy of reaction temperature is mostly determined by frame of the simulation apparatus during experiment. Hydrocarbon generation experiments for different source rocks in the same system with different pressures have important significances in discussing the influence of temperature and pressure on the hydrocarbon generating ability of source rocks.
