| 摘 要： | 采用封闭体系程序升温热模拟实验装置，开展了不同压力条件对塔里木盆地哈2井三叠系灰黑色泥岩和英东2井深灰色泥灰岩样品产气率影响的研究。利用水作为压力介质，根据不同的加水量产生不同的压力，研究压力效应对模拟实验结果的影响(样品的加热温度为450℃，时间为24 h)，结果表明，压力对产气量可能有一些影响，但不太明显，这可能反映了在低压条件下烃源岩产气量与压力关系不大。

| Abstract: | By means of thermal simulating experiment in the close system, the authors have studied the effect of different pressures on the hydrocarbon generation of source rock (the Triassic greyblack mudstone from well Ha 2 and the deepgrey limestone from well Yingdong 2 in Tarim basin). A series of simulating experiments have been completed utilizing water as pressure medium according to different volumesof water making different pressures. The simulating temperature is 450℃ and the time is 24 hours in the experiment. The results show that the effect of pressure variation on hydrocarbon generation is available but not obvious, suggesting that the relationship between pressure variation and hydrocarbon generation of source rock is not close under the condition of low pressure in the close system. |
