【摘要】 本文在充分利用杏六东地质信息的基础上,结合现场提供的夹层空间分布,通过布虚拟井,构造厚度点数据,建立虚拟地层面等方法建立侧积夹层构造三维地质模型,采用相控建模技术,建立了该区块的孔隙度、渗透率、含油饱和度、净毛比属性模型,该模型与实际符合程度较高。对地质模型进行了粗化,模型粗化时采用了算术加权平均方法,从而使粗化的模型能够真实反映原模型的地质特征及流动响应。进行了历史拟合,拟合过程中,分析了对开发指标敏感的参数并提出了拟合技巧。给出了夹层控制下的剩余油分布特点,即垂向上底部高度水淹,顶部剩余油富集。在Brigham-Smith模型的基础上,给出了用示踪剂方法计算来水量的理论公式,给出平面上各方向来水比例的确定方法,并用理论模型验证理论公式准确。通过拟示踪剂研究了油水运移规律。侧积体内的流体由下往上推移;流体很难穿过夹层进行流动;流体在侧积体内的运移受到重力和压力差双重作用的影响。通过拟示踪剂方法确定了两口水平井X5-4-A35和X6-1-A35的平面来水方向和纵向上的来水层位以及平面和纵向的来水量。更多还原

【Abstract】 The three-dimensional structural models of lateral depositional layer are built base on the geological information of the eastern Xing-6 block and the on-site interlayer distribution using a series of technique such as adding vietual wells, building thickness data, and building a virtual gound level.Using the control of sedimentary facies, the precise peoperty model with porosity, permeability and oil saturation and NTG are established.This model accords the actual situation with high degree.The geology model is coarsened.In model coarsening process, arithmetic weight average method is used, thus it enables the coarsening model reflects the form geological feature and the flowing response really. In the history matching process, the parameters sensitive to developing target are analyzed and the matching skills are proposed.The characteristics of remaining oil distribution are given, namely the vertical upward bottom is water flooding, the oil is on the top.The method to determine the inflow percentage of each direction was derivated base on the Brigham-Smith model.The formula is proved by the theory model.Oil-water migration rule is determined by the quasi-tracer method. The fluid in the lateral layer folws from bottom to top.Fluid flow through the interlayer is difficult. The flow of fluid in the lateral layer is under the influence of by gravity and differential pressure. Inflow direction of plane and zones that water breakthrough of vertical of X5-4-A35 and X6-1-A35 were determined using the quasi-tracer method.更多还原
