大庆杏树岗油田杏六中区储层四维地质建模

以大庆杏树岗杏六中区储层为例，提出了建立油藏四维地质模型的方法。根据已有资料，完成构造模型和砂体模型建立。在砂体模型约束下，通过将不同时期侧井解释成果进行归类，以不同时期水庵侧井资料为条件，水庵动态分析结果为指导，采用序贯指示建模方法，完成不同时期水庵地质模型的建立。不同时期的水庵地质模型揭示了地下流体随开发过程的动态变化：总体上，研究区水庵状况由未水庵向中高水庵方向发展;不同区域水庵时期及程度均有差异，注入水水线推进方向和速度上的差异导致局部剩余油气分布差异。模型较好地反映了不同时期的油藏水庵特征，准确揭示了剩余油时空演化和分布特征，为油藏开发调整和剩余油挖潜奠定了基拙。

4-D geological modeling of Xing 6 Middle Area reservoir in Xingshugang Oilfield of Daqing

The paper proposes a method of 4-D geological modeling taking Xing 6 Middle Area reservoir in Xingshugang Oilfield as an example. The structural model and sand body model are established based on existing data; then the reservoir performance of different period is analyzed by using the data of waterflooding well under the constrain of sand body model; finally, the waterflooding geological models of different period are built under the constrains of sand body model and using the Sequential Indicator Sinmlation. The models reveal the oil and water distribution and the characteristics of waterflooding during the production period, Overall, the waterflooded conditions develop from low waterflooding to high waterrfooding in study area. There are differences between the waterflooding period and watertlooding degree in different regions, which reflects the difference in development direction and speed of injected water line, resulting in tile differences of local residual oil and gas distribution. The model accurately reveals the time and space evolution and distribution characteristics of remaining oil, which lays a foundation for the adjustment of reservoir development and the potential tapping of remaining oil.
