Physical Simulation Experiment and Mechanism Analysis on Oil Migration and Accumulation in East Liaodong Area
辽东东地区石油运移和聚集物理模拟实验及机理分析

A 2-D experiment model was used for modeling oil migration and accumulation in the East Liaodong area. The results show that: (1) The moving pattern of oil in the fault zone has great influence on the oil migration pathway. (2) The 3 unconformities have different transporting capacity for oil in different injection conditions. Oil migrated in the unconformity 1 between Ng2 and Ed under the continuous or impulsive injection conditions. The other two unconformities (the unconformity 2 and the unconformity 3) had lateral transporting capacity only when impulsive injection took place. (3) Oil accumulation in the sandbody of Dongying formation depends on its relationship with other passage systems. The pinchout sandbody connecting with the oil source fault is most conducive to the formation lithological reservoirs.
