摘要
采用自制的实验装置，对褐煤样品进行了生、排油模拟实验。通过对实验产物的系统分析得知，煤岩在演化过程中可以生成数量可观的煤成油，在Ｒｏ＝１．２５％处达到生油高峰，其生油量约为４６ｋｇ／ｔ；实验证明生成的部分煤成油可以从母体煤岩中运移出来，在Ｒｏ＝１．５０％处达排油高峰，此时排油量可达１４ｋｇ／ｔ。还对煤岩的排油能力与泥岩的排油能力进行了比较。对该煤岩残余油及排出油的组分分析表明，煤成油排出过程中存在明显的“组分分异现象”。
Oil generation and migration from coal simulated experiments have been carried out by means of the experimental installation made by ourselves, the experimental products are analyzed systematically. The results show that coal may generate lots of oil in the evolutionary process, the amount of with is about 46 kg/t in the peak oil generation ( R o=1.25%). But also the experiments show that part of the oil from coal may come out of the coal, the migratory amount reaches about 14 kg/t in the peak oil migration( R o=1.50%). The expulsion efficiency is compared with that of the mudstone of Songliao Basin. In addition, the residue oil and removed oil components from the coal have been analyzed, the “components isolation” phenomenon exists in the process of oil migration. The experimental results are studied and discussed, it is concluded that oil from coal should be regarded as a further exploration direction to Hailaer Basin.
