| 摘 要： | 对下马岭组灰岩进行了热模拟实验,对碳酸盐岩腐泥型有机质的热演化规律进行了研究,划分了其演化阶段,给出了成熟度指标和各阶段油气产率.研究表明,矿物对有机质热演化的影响,在成熟阶段主要表现为催化作用;在高过成熟阶段则主要表现为对干酪根裂解、脱氧和缩合有阻碍作用.沥青“C”的某些成熟度指标可较好地反映有机质成熟度;在缺乏镜质体时焦沥青反射率可作为有效的成熟度指标.此外还对比了岩样和干酪根的模拟结果,以及沥青“A”和“C”的差异.

| Abstract: | The thermal simulation experiment of Xiamaling limestone was carried out to identify evolution stages, establish maturation indicators and predict oil and gas generation rates . The result shows that the influence of minerals on the thermal evolution of organic matter is mainly catalytic in the mature stage, but they inhibit the cracking, deoxygenation and condensation of kerogen in the overmatured stage. Some maturation indicators of bitumen "C " can show the maturation level of organic matter. The pyrobitumen reflectance is an effective indicator in the absence of vitrinite. The thermal simulation results of rock sample and kerogen, as well as bitumen "A " and "C " are compared. |
