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。
The authors conducted simulation experiments with different heating times, water additions and sample particle sizes. It was found that heating time, water addition and sample particle size had a significant effect on the productivity of simulated experiments. With prolonged time, the oil yield is obviously reduced, while the hydrocarbon gas yield is greatly increased. Hydrocarbon gas production, residual oil content, discharged oil content, total oil yield, and total hydrocarbon yield both increased significantly with increasing water content from 0% to 20% and 50% Total hydrocarbon yield was significantly reduced, hydrocarbon gas production is still gradually increased. Compared with 5 ~ 10mm large particle samples, the total gas production rate and hydrocarbon gas production rate of 1 ~ 2.5mm small particles increased obviously, and the total oil and total hydrocarbon yield decreased obviously. Warming time and water addition have different effects on the oil family composition, hydrocarbon saturation, GC-MS, carbon isotope of gas and oil, pyrolysis of kerogen, and atomic parameters such as atomic ratio of H / C and O / C Clearly affected.
