摘　　要：油藏开发与成藏运移都具有借助流体传递能量建立动态平衡的特征,二者具有动态相似性。作者运用油藏开发中的毛管压力曲线对透镜状砂岩体油藏成藏运移的机理给予了合理解释,并分别对透镜状砂岩体油藏烃源岩的幕式排烃机理和砂岩体阶段式充注机理进行了系统阐述。透镜状砂岩体油藏成藏运移过程中幕式排烃和阶段式充注是相对独立的两个过程,只有当二者协调一致时,才能完成透镜状砂岩体油藏成藏过程。Oil reservoir development, formation and migration have the character to make the dynamic balance by means of the fluid to convey the energy. Both of them have the same dynamic. The capillary curve for oil reservoir development can be used to interpret reasonably the reservoir migration. The formation mechanism of screen expulsion hydrocarbon for hydrocarbon source rocks and the formation mechanism of stage fill for sandstone have been separately explained in the paper. For the lens-type sandstone reservoir migration, screen expulsion hydrocarbon for hydrocarbon source rocks and stage fill for sandstone are two separate processes. Only when the two processes are consistent, the lens-type sandstone reservoir is formed.
