| 中文摘要:文章尝试利用砂岩颗粒中的微裂隙穿插关系及测定微裂隙内充填物中的盐水包裹体的均一温度来确定包裹体的形成期次；结合构造发育史、烃源岩演化史和古地温梯度恢复各期包裹体形成时的埋藏深度及时间；最后通过观测各期流体包裹体中是否含有烃类及烃类包裹体的发育程度来确定油气运移期次及主次关系、运移时间。发现油气运移、成藏时间主要发生在烃源岩大量生烃后的第一次构造运动时间段内。 |

| Abstract:In this paper, the penetrating relationship of microfissures in sandstone grains was used to determine the homogenization temperature of salt_water inclusions in the cement within microfissures and the formation ages of inclusions. Combined with structural development, source_rock evolution and paleogeothermal gradient, this paper restored the burial depth and time for the formation of inclusions of various ages. Based on observing the existence or nonexistence of hydrocarbon inclusions in fluid inclusions of various ages and the development extent of hydrocarbon inclusions, the authors also deal with the ages and time as well as the primary and secondary relations of hydrocarbon migration. |
