摘要:
      在油田开发方案设计阶段,基础地质资料尤其是钻井资料相对较少,因此对储层分布的认识具有较大的不确定性。沉积相建模为储层分布不确定性的定量表征提供了技术手段,但每种沉积相建模方法具有各自的适应性。以渤海P油田为例,分别应用布尔模拟和示性点过程模拟方法,以河道带和河道内砂体为描述对象建立了2种沉积相模型,定量表征2种储层分布模式,分析2种模拟结果的储层分布规律,指出以河道内砂体为描述对象的建模方法提供了该油田储层分布的最可能模式,而以河道带为描述对象的建模方法提供了储层分布的另一种可能模式,为油藏数值模拟方案设计和敏感性分析提供了地质依据。

Abstract:
      In the designing of oilfield development plan, the basic geological data, especially the drilling data, is relatively small, so the understanding of reservoir distribution lacks certainty. Sedimentary facies modeling provides a technical means for quantitative characterization of reservoir distribution uncertainty, but such modeling method has its own adaptability. Taking the Oilfield P in the Bohai Sea as an example, the Boolean simulation method and marked point process simulation method are applied respectively. Two sedimentary facies models are established by using the river channel and the sand body in the river channel to quantitatively characterize the two reservoir distribution patterns. The reservoir distribution law of the two simulation results indicates that the modeling method using the sand body in the river channel as the description object provides the most probable mode of reservoir distribution in the oil field, and the modeling method with the river channel as the description object provides another probability of the reservoir distribution, which provides a geological basis for reservoir numerical simulation scheme design and sensitivity analysis.
