Determination of reflectance of organic matter by digital image processing

摘要

摘要: 有机质反射率参数是烃源岩评价和盆地热演化史研究的基础数据。目前有机质反射率的测量工作主要依靠人工手动方法，人为主观因素对测量结果影响较大。从图像传感技术出发，探寻镜质体反射率与灰度图像之间的相互关系，尝试建立利用镜质体灰度图像表征反射率值的方法。分别对标准物质和地质样品开展了镜质体反射率和灰度级的对应测量工作，发现两者具有极好的重合特征，表明利用灰度级定量镜质体反射率的方法具有可行性。但对于高过成熟阶段，两者的关系尚有待深化研究。

Abstract: The reflectance of organic matter is a basic parameter for source rock assessment and thermal evolution history study in a basin. At present, the main technique for reflectance measurement is manual despite heavy operator influence on the results. This paper discussed the relationship between vitrinite reflectance and grey level determination by digital image processing, and tried to determine the vitrinite reflectance by grey level. Simultaneous measurements of vitrinite reflectance values and grey levels were implemented on standard materials and geological samples. The trends of vitrinite reflectance values and grey levels coincide with each other, which demonstrate that it is feasible to quantify the vitrinite reflectance using grey level. For high-over maturity, however, more research is needed.
