摘要
硫酸盐热还原作用(TSR)成因的硫化氢是高含硫天然气藏中硫化氢的主要来源,深入研究TSR反应机理,需要开展系统深入的模拟实验。但是,不同材料制作的实验装置,实验结果相差甚远。为了探讨实验装置材料对实验结果的影响,该文对高温高压合金釜、石英管以及金管等实验装置进行了对比试验。实验结果证实:①高温高压合金釜的金属参与反应形成金属硫化物,不适合用于TSR模拟实验;②高温高压条件下,石英可以跟硫酸盐反应生成硅酸盐,因此石英管也不适合用于TSR模拟实验;③黄金不与TSR反应物、中间产物或者产物中的任何一种物质发生反应,黄金管—高压釜限定体系装置虽然受金管容积所限,模拟产物量不足以进行轻烃指标的分析,但是其产物量足以进行气体产物组分及碳同位素测试,是较好的一种TSR模拟实验装置。
Thermochemical sulfate reduction（TSR） is the major mechanism of gas reservoirs with high content of sulfureted hydrogen.The complexity of TSR mechanism demands further research which needs comprehensive simulation experiment,but different simulation experiments with different instruments lead to great diversity.In order to investigate the influence of instrument material on experimental results,a series of contrast experiments have been done.With the experiments,the followings are confirmed： ①The metal in high temperature and pressure kettle reacts with sulfur to generate metallic sulfide,so composition metal kettle is not suitable to be used as an instrument for TSR simulation experiment;②In high temperature and pressure conditions,quartz reacts with sulfate to generate silicate,so quartz tube can not be used for TSR simulation experiment;③Gold does not react with the reactant,intermediate reaction product or final reaction product,for the limited bulk volume of golden cube,the hydrocarbon product is not enough for testing light hydrocarbon,but it＇s enough for testing gaseous hydrocarbon components and carbon isotopes,so it is the best option to use golden cube for such kind of simulation experiment.
