In this paper ， the process of hydrocarbon generation and evolution in the four thermal evolutionary stages （ low - mature ， mature ， high - mature ， overmature ） of geohistory is simulated by selecting low - mature hydrocarbon source rocks and using the method in which hydrocarbons are generated from artificial pyrolysis and petroleum migration is controlled properly 本文选用低成熟烃源岩，采取人工热解生成油气及适当控制石油运移的方法，模拟了4个地史热演化阶段（低熟、成熟、高熟、过熟）中油气的生成演化过程。
It has the essential source conditions for the formation of immature oil with higher abundance and better types of organic matter deposited in thicker stratum under the environment in favor of preservation of organic matter and its inversion to hydrocarbons at the early stage , as well as the appropriate maturity for abundant production of immature oil 该套泥岩不但具备有机质丰度高、类型好、单层厚度大等生成低熟油必备的物质条件以及有利于有机质保存和向烃类早期转化的沉积环境条件，而且其热演化程度正处于生成低熟油的高峰阶段。
It is pointed out that in the studied area there exist katogene metamorphism ( area ) ; igneous contact metamorphism , where the katogene metamorphism is dominated , the igneous contacting metamorphism is only distributed in yongzheng area etc , for which the influence of thermal evolution is greatly limited 指出研究区存在深成（区域）变质和火成接触变质两种类型，且以深成（区域）变质类型为主，火成接触变质类型仅分布在永城等局部地区，对有机质热演化的影响范围极为有限。
Because of the above mentioned reasons , the first one should be considered the main source rock in yili basin . by means of the modeling of the buried history and the history of thermal evolution , it can be concluded that this set of source rock had entered the ceiling of the oil - generating window in the early triassic period and reached its peek in the middle and end of triassic period , befor entering the highest maturity in the early and middle jurassic period , and had generating gas in the end of jurassic period 其中铁木里克组烃源岩厚度大、有机质丰度高、成熟度高，具有较高的生烃潜力，是伊犁盆地主要的烃源岩系，通过埋藏史及热演化史模拟，该套烃源岩于三叠纪早期已进入生烃门限，中晚三叠世达到生、排烃高峰，早中侏罗世进入高成熟阶段，侏罗纪末进入生气阶段。
In this paper , thermal evolution history of organic matter of the source rocks and hydrocarbon generation history have been researched by tti method , hydrocarbon migration direction and migration times were probed combining with the area structure development feature ; distribution pattern of the main reservoir intervals on lateral and longitudinal have been predicted by researching on development feature and control factors of the reservoir intervals , the actions of reservoir conditions in hydrocarbon accumulation and bearing also were probed combining with pore evolution feature ; the micro - pore feature of regional cap and direct seal in carboniferous - lower triassic in this area have been determined with micro - capillary pressure curve and intrusive mercury curve ; the prospecting districts have been pointed out combining with the hydro - geologic feature , the potential reservoirs were classified according to trap types in this area , the author attempt to evaluate on the hydrocarbon - bearing condition in the str ata of carboniferous ~ lower triassic from hydrocarbon generation and migration reservoir condition , reserved condition etc , and predict the reservoir types and hydrocarbon - bearing patterns combining with the structure evolution . based on above , the author point out that the central block of chenghu - tuditang synclinorium and the southern block of dangyang synclinorium are the advantageous regions for exploration 本文用tti方法研究了烃源岩有机质的热演化史和油气生成史，并结合区内构造发育特征，探讨油气在区域上的运移方向和在时间上的运移期次；通过对储集层段的发育特征和控制因素的研究，预测了本区主要的储集层段在横向上和纵向上的分布规律，并结合孔隙演化特征，探讨储集条件在油气聚集成藏中的作用；利用微毛细管压力曲线法和压汞法，对石炭系?下三叠统的区域盖层和直接盖层的微孔隙特征进行了定量评价，并结合水文地质分布特征，指出有利于油气保存的地区；根据区内存在的各种圈闭类型，对可能存在的油气藏进行了分类，并试图从油气的生成与运移、储集条件、保存条件等方面，动态地综合评价石炭系?下三叠统油气成藏条件，并结合构造演化特征，预测其油气藏类型和成藏模式。
Kinematic models have predominance in predicting heat flow but weakness in simulating basin geometry ; kinematic - rheological models are adept in tectonic modeling , but identical with kinematic models in heat flow prediction ; dynamic models contain latent advantages and also some obstacles in tectono - thermal modeling 运动学模型在预测盆地热流演化方面具有优势，但在预测构造沉降等几何形态方面存在一定的缺陷；运动学流变学模型的优势在于构造演化模拟，在热演化方面类似于运动学模型；动力学模型蕴含着潜在的巨大优势，只是目前还存在一些阻碍因素。
According to the chemical experimental data of residual organic carbon content , kerogen carbon isotope , aliphaltic gas chromatography mass spectrometry of 67 outcrop specimens in the baise basin , the authors analyse the geochemical characteristics of the type and the maturation of organic matter in the lower triassic - devonian source rock 根据百色盆地周缘大量露头样品的残余有机碳含量、干酪根碳同位素、饱和烃色谱及色质等地球化学实验数据，分析了下三叠统泥盆系海相烃源岩的有机质丰度、类型、热演化程度。
