辽河盆地葵花岛构造裂隙发育的有限元模拟
|
摘要
利用精细地震剖面解释方法和平衡剖面正演技术建立葵花岛构造有限元模拟的地质模型 ,在此基础上利用构造裂隙发育的有限元法模拟技术提出了葵花岛构造在模拟应力场情况下 ,裂隙发育最有利的地区是葵花岛构造西侧边界断层下盘的东营组三段 ,并指出了葵花岛构造西部断裂西侧东营组三段的断鼻构造和葵花岛构造的深层———沙河街组一段的圈闭构造是葵花岛构造进一步勘探的方向。这项研究对指导辽河油田的油气勘探具有重要意义。
The Kuihuadao Structure was a suborder unit of the East Depression, Liaohe Basin, where was an important region for oil gas exploration. Depending on the results got from accurate seismic profile interpretation and balanced cross section analysis, the geological model for finite element simulation of fracture development was established. The region where the fracture was most developed in the Kuihuadao Structure was in sedimentary period of the Third Member, Dongying Formation in footwall of western boundary fault at the simulation stress according to the results of finite element simulation. Combining with some other fruits, this paper also suggested that the trap in the Third Member, Dongying Formation in footwall of western boundary fault and the trap in the First Member, Shahejian Formation in central Kuihuadao Structure might be good prospect trap for oil gas exploration.
