辽东东地区石油运移和聚集物理模拟实验及机理分析

采用二维物理模型对辽东东地区石油运移和聚集进行了实验研究，结果证实：①断层带的石油运移方式对石油运移路径产生了重要的影响；②3套不整合面在不同充注方式下对石油的输导作用不同，馆陶组下段和东营组之间的不整合面（不整合面1）在2种充注方式下对石油都起到输导作用，东营组与沙河街组之间的不整合面（不整合面2）和沙河街组沙二段与沙河街组沙四段之间的不整合面（不整合面3）仅在幕式充注情况下对石油的运移起到侧向输导作用；③东营组砂体最终能否成藏，取决于砂体与其他输导体的匹配关系，其中与油源断层相沟通且尖灭的砂体最有利于形成岩性油藏。

Physical Simulation Experiment and Mechanism Analysis on Oil Migration and Accumulation in East Liaodong Area

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.
