针对东濮凹陷文南地区沙二下亚段(Es_2~下)构造破碎、断层多且切割关系复杂、断层产状弧度大,难以建立高精度的三维构造模型的问题,论文以文38 Es_2~下为解剖对象,在深度域精细构造层位解释及断裂系统解释成果基础之上,运用Petrel建模软件,通过理清断层的平面及剖面组合关系,结合断层产状的复杂程度,选择Lisric Pillar和Curved Pillar两种方法来控制断层倾斜程度,再通过选择适宜的网格步长,以及人为扩大研究区范围边界等方法,建立了文38 Es_2~下的高精度三维构造模型,研究成果不仅为后期精细属性建模及油藏数值模拟奠定了基础,同时也为东濮凹陷相似地质条件油田的构造建模在一定上提供技术支持及方法借鉴。
In order to solve the problem that it is difficult to establish a high-precision three-dimensional structural model because of the structural subsidence in Es2 ~ Lower Es2 ~ Lower Wennan region in Dongpu Depression, the complicated faults and complicated arcs, Under the anatomical object, based on the interpretation of the detailed structural horizon in the deep domain and the interpretation of the fault system, Petrel modeling software was used to select Lisric Pillar by discerning the plane and section combination of the fault and the complexity of fault occurrence. And Curved Pillar two methods to control the tilt of the fault, and then by selecting the appropriate grid step, and artificially expand the scope of the study area boundaries and other methods to establish a high precision three-dimensional model 38 Es_2 ~ under the construction of not only The late fine attributes modeling and reservoir numerical simulation laid the foundation for the same geological formations in Dongpu sag similar geological conditions in the field to provide some technical support and methods of reference.
