从有机生油理论来看,温度和热梯度是有机质向石油转化的主要条件。在生油母质的转化过程中,热催化分解是重要的机理。因此,温度和热梯度是颇为重要的。本文用目前世界特大油气田的资料与全球热流值的分布进行对比,并结合我国各油区油层温度资料对石油生成作些初步探讨。 From organic oil theory, temperature and thermal gradients are the main conditions for the conversion of organic matter to petroleum. In the transformation of raw oil parent material, thermal catalytic decomposition is an important mechanism. Therefore, temperature and thermal gradients are important. In this paper, the data of the world’s largest oil and gas fields are compared with the distribution of the global heat flow values, and some preliminary discussions are made on the oil generation based on the reservoir temperature data of various oil-bearing areas in China.
