摘　　要：为了简化室内配制含不同溶解气原油的操作步骤及提高实验结果的可靠性,通过CMG数模软件中的winprop模块建立地层流体相态组分模型.根据实验数据对模型拟合修正,进行相态分析计算,然后参考模型计算的数值配制相应压力下的含溶解气原油,并准确测定溶解气油比值和预测相关的流体参数.实验方案的优化设计简化了实验流程,提高实验效率.同时,通过实例分析验证实验方案的可行性,并且发现了随溶解气油比增加超低渗岩心油相渗透率上升的现象.In order to simplify the operation steps of indoor preparation of crude oil containing different dissolved gases and improve the reliability of experimental results,a phase composition model of formation fluid was established by means of the winprop module in CMG numerical simulation software.According to the experimental data,the model is fitted and corrected,and phase analysis and calculation are performed.Then,the crude oil containing dissolved gas under corresponding pressure is prepared with reference to the numerical value calculated by the model,and the dissolved gas oil ratio is accurately measured and relevant fluid parameters are predicted.The optimized design of the experimental scheme not only simplifies the experimental process,but also improves the experimental efficiency.At the same time,the feasibility of this scheme was verified through case analysis,and the phenomenon of oil phase permeability increasing in ultra-low permeability cores with the increase of dissolved gas oil ratio was also found.
