摘要: 基于单砂体沉积特征,建立了曲流河及三角洲水下分流河道储集砂体的平面与垂向上的组合关系,及其对应的测井识别标志。分析曲流河及三角洲分流河道储层的构型刻画方法,并利用多种方法对侧积体规模、前积层与侧积层产状进行定量计算,刻画单砂体内部构型。探索基于多级构型界面约束的构型建模方法,有别于传统的网格约束,该方法综合采用多级界面约束和设置非均质网格技术,实现了以较少量网格对构型级别夹层的精细表征。同时解析常规产能劈分方法,探索单砂体产能劈分要素,提出了多参数相结合的产能劈分方案,进而为油田未来精细调剖挖潜方案的制订提供技术及理论支撑。

Abstract: Based on the sedimentary characteristics of single sand body, the lateral and vertical sand body architecture relationships of meandering river and delta distributary channel facies are established, as well as their corresponding logging identification marks. The characterization methods of reservoir architecture of meandering river and delta distributary channel facies are analyzed and quantitative calculations on the scale of lateral accretion bodies and the occurrence of foreset and lateral accretion layers are conducted by using multiple methods, so as to describe the internal architecture of single sand body. The architecture modeling method constrained by multi-level architecture interface is researched. Different from the conventional methods constrained by grid, multi-level interface constraint and heterogeneous grid technology are integrated in this method to achieve the fine characterization of the architecture level interlayer with a small number of grids. In addition, the conventional capacity splitting methods are analyzed to identify the elements for capacity splitting of single sand body, and a multi-parameter capacity splitting scheme is proposed, which provides technical and theoretical support for the formulation of potential tapping schemes of oil fields in the future.
