摘要
In this paper, a thermodynamic modeling method was employed, and two types of black oil and volatile oil were used to simulate their homogenization temperatures and to establish the homogenization temperature relationship between petroleum inclusions and their coeval aqueous inclusions under different P-T conditions. It is concluded that all the petroleum composition, trapped temperature and pressure have influence on the petroleum inclusion homogenization temperature. In contrast, if the trapped P-T and petroleum composition of single inclusion are known, the petroleum inclusion homogenization temperature and the difference between petroleum inclusions and their coeval aqueous inclusions can give geological meanings, which can play a great role on hydrocarbon charging episodes and paleofluid pressure modeling.
