为提高VTflinc软件计算最小捕获压力的准确度，通过岩相学、荧光光谱、模拟试验等方法和手段对该软件所需的参数进行研究。结果表明：荧光干扰导致油包裹体边界失真是气相充填度计算误差产生的主要原因。透射光图片无荧光干扰，可作为标准校正CLSM光切片中的油包裹体的边界；根据空间相近原则选择亲缘性油藏作为初始组分，其条件不够充分，还应考虑荧光的一致性；油/水伴生包裹体判识时应首先考虑包裹体的产状和期次，判识后也要注意发生次生变化的油/水伴生包裹体，并将其剔除。

In order to improve the accuracy of calculating minimum trapping pressure with the software VTflinc, the param-eters involved were rsearched by means of petrographic methods, fluorescence spectroscopy and simulations. The results show that the fluorescence interference which causes oil inclusions border distortion is the main cause of the calculation er-rors of degree of gas bubble filling. As transmitted light photos have no fluorescence interference, they can be used as a standard to calibrate borders of oil inclusions in the CLSM optical slices. It is not sufficient to select oil from related reser-voirs based on similar space as the initial component, and the consistency of fluorescence should also be considered. The occurrence and phase of inclusions should be considered firstly when identifying the coeval petroleum and aqueous inclu-sions. Attentions need to be paid to the coeval petroleum and aqueous inclusions in secondary changes, which need to be removed after identified.
