鄂尔多斯盆地上古生界泥页岩热模拟实验
|
摘要
采用高压釜热模拟实验对鄂尔多斯盆地上古生界太原组、本溪组的4块泥页岩样品进行了生烃过程模拟分析。在热模拟实验过程中,甲烷气是最主要的气态烃类产物,其产率在热模拟过程中持续增加,在温度600℃时可达50 mg/g。C2～C5的产率变化在热模拟过程中表现出相似的特征,均是先增大至峰值后开始减小,C2～C5的热裂解是甲烷产生的主要来源。样品的气态烃产率主要与有机质热成熟度有关,热成熟度越低,样品有机质的生烃潜力越大,在热模拟过程中气态烃的产率越高。
In order to simulate and analyze the process of hydrocarbon generation of 4 shale samples from the Late Paleozoic Taiyuan Formation and Benxi Formation in Ordos Basin,thermal simulation experiments were made with high-pressure autoclave. In the experimental process,methane was the major gaseous hydrocarbon product which production rate continued to increase,up to 50 mg /g when the temperature reached to 600 ℃. Changes of production rate of C2～ C5showed similar characteristics in the experiments: firstly increasing to the peak value and then beginning to decrease,and thermal cracking of C2～ C5was the main source of methane production. Gaseous hydrocarbon production rate of the samples was mainly related to the thermal maturity of organic matter. The lower the thermal maturity was,the greater the potential of hydrocarbon generation of organic matter was,as a result,the production rate of gaseous hydrocarbon was higher in the process of thermal simulation experiments.
