摘要

摘要: 通过有机质热解模拟实验建立的残留物镜质体反射率值与产烃率之间的关系图与自然演化剖面获得的产烃率曲线存在一定差异,即相同的镜质体反射率值代表的成熟度存在差异。根据镜质体反射率的分阶段演化规律,利用Easy%R_o模型和干酪根H/C原子比与R_o值的对应关系,提出了热解模拟实验的Easy%R_o校正图版以及H/C原子比的分段校正思路和校正公式。利用校正的R_o值所作的热解模拟实验产烃率曲线与现今认可的生油演化模式较为接近。

Abstract: The relationship between the vitrinite reflectance of residual matter and hydrocarbon yield rate was established through pyrolysis experiments that simulated maturation of organic matter. R_o values calculated through pyrolysis simulation indicative of different maturities were compared to natural evolution profiles. Using these data, an Easy%R_omodel and the relationship between H/C ratio and R_o of kerogen were applied based on the multi-stage evolution of vitrinite reflectance. We put forward an Easy%R_o correction chart, a multi-stage H/C correction approach and the formula for the pyrolysis simulation experiment. The hydrocarbon generation model rebuilt using the corrected vitrinite reflectance was much closer to the natural evolution model.
