单砂体形态及分布特征预测是精细油藏描述的主要内容。然而,利用常规随机建模技术所建立的模 型与油藏实际往往差别较大,难以精确预测含油单砂体展布。如何运用开发中后期丰富的资料和三维地 质建模技术刻画单砂体在三维空间的展布规律,建立准确实用的三维地质模型是目前油气田开发中后期 要解决的关键问题之一。以华北油田某区块为研究对象,对单砂体建模技术的实现方法和实际应用进行 论述,通过与常规随机建模结果进行对比表明:单砂体模型既能清晰地表征储层内多期砂体的叠置关系, 也能揭示三维空间中单砂体的分布和尖灭;同时又充分表达了地质研究的认识,为油气田开发提供了更 加方便可靠的资料,尤其适合开发中后期井网较密、储层研究达到单砂体级别的情况。

The prediction of single sand body morphology and distribution characteristics is the main contents of fine reservoir description.The model established by using conventional stochastic modeling techniques is greatly different to the actual reservoir, so it is difficult to predict the distribution of oil-bearing sand body. Using the data from the late development and three-dimensional geological modeling techniques to describe the distribution characteristics of a single sand body in three-dimensional space and to establish accurate three-dimensional geological model is one of the key issues to solve the oil and gas field development in late period. Taking a block ofHuabei Oilfield as an example, we discussed the implementation and practical application of modeling techniques to a single sand body by conventional stochastic modeling. The result shows that a single sand bodymodel can not only clear characterize reservoirs within the multi-sand body superimposition, but also reveal single sand body distribution and thinning out in the three-dimensional space, which express the fully understanding of the geological research, providingmore convenient and reliable data for oil and gas field development, especially suitable for the late stage of development with the high frequencywell network in the scale of single sand body.
