摘要
///Under the simulation from the actual reservoir temperature and pressure conditions, hydrocarbon-bearing inclusions were synthesized and the modes of hydrocarbon-bearing inclusions forming in carbonate rock reservoirs were studied. Results from synthetic hydrocarbon-bearing inclusion experiments show that the hydrocarbon-bearing inclusions can be trapped through healing the crystalline imperfections under reservoir bearing gas and oil condition. According to the types of crystalline imperfections and the petrographic characteristics of inclusions, the modes of hydrocarbon-bearing inclusions trapped can be divided into four groups. The inclusions trapped in line defect usually have different volumes. The number of inclusions trapped in face defect mode is less and usually thinner. And the space defect mode is difficult to form inclusions.Compared to the natural samples, secondary inclusions trapped in line defect mode are the most common ones and also the most common ones in inclusion analysis.
