摘要

摘要: 该文作者进行了不同加温时间、加水量和样品颗粒大小的模拟实验,发现加温时间、加水量和样品颗粒大小对模拟实验油气产率有明显影响。延长时间,产油率明显降低,而烃气产率大大增多。加水量由不加水(0%)到加水20%和50%时,烃气产量、残留油量、排出油量、总油产量、总烃产量均明显增加,加水量再增多,产油率和总烃产率均明显降低,烃气产量仍逐渐增加。1～2.5mm的小颗粒样品与5～10mm大颗粒样品相比较,总产气率、烃气产率明显增加,总油和总烃产率明显降低。加温时间、加水量对油的族组成、饱和烃色谱、饱和烃色谱-质谱、气和油的碳同位素及干酪根的热解和H/C、O/C原子比等地化参数均有明显影响。

Abstract: The simulation test of source rock under different heating time,added water amount and sample grain size was carried out.The yield of oil and gas in the simulation test of source rock varied obviously with different heating time,added water amount and sample grain size.When extending heating time,the oil yield was obviously decreased,and the gas yield of hydrocarbon was greatly increased.When added water amount was changed from 0% to 20% and to 50%,the gas yield of hydrocarbon,the remained oil,the expulled oil,the total oil yield and the total hydrocarbon yield were all obviously increased.When added water amount was more than 50%,the total oil yield and the total hydrocarbon yield were obviously decreased,but the gas yield of hydrocarbon was increased.From 1-2.5mm to 5-10mm of grain size,the total gas yield and the gas yield of hydrocarbon were obviously increased,and the total oil yield and the total hydrocarbon yield were obviously decreased.The simulation test of source rock under different heating time,added water amount and sample grain size showed that the component of oil,the GC and GC-MS of saturated hydrocarbon,the δ¹³C of gas and oil,the pyrolysis of kerogen,the H/C and O/C atom ratio of kerogen and other geochemical parameters were affected.
