对铁岭灰岩抽提除去沥青“Ａ”后的残渣进行高温高压模拟实验。模拟实验研究表明，晶包有机质的释放与温度和压力有关，高压有利于晶包有机质释放。晶包有机质和干酪根主要释放出低碳数烷烃，Ｐｒ／ｎＣ１７ 、Ｐｈ／ｎＣ１８ 在热演化过程中变化不大，Ｐｒ／Ｐｈ 则波动较大。７０％ 左右的晶包有机质在Ｒｏ 为２ ．２％ 前释放。干酪根热降解所生成的烃类没有进入到残留的晶包有机质中。高压下晶包有机质的热演化要比低压时慢。
High temperature and high pressure simulation experiments were carried out on the residue after extracting and removing asphalt “A” in Tieling limestone. Simulation experiments show that the release of organic matter is related to temperature and pressure, and the high pressure is favorable for the release of organic matter in the crystalline inclusion. Pristine organic matter and kerogen mainly released low-carbon alkanes. Pr / nC17 and Ph / nC18 changed little during thermal evolution and Pr / Ph fluctuated greatly. About 70% of the crystalline inclusions have Ro at 2. 2% before release. The hydrocarbons generated by thermal degradation of kerogen do not enter the residual crystalline inclusion organic matter. The thermal evolution of organic matter under high pressure is slower than that under low pressure.
