摘要:

多点地质统计学方法通过扫描训练图像得到多点之间的相关性,其能够很好地描述地下储层的展布形态和分布规律。 与传统的两点地质统计学通过变差函数描述两点的相关性相比,多点地质统计学方法能更好地描述储层的空间相关性。介绍了多点地质统计学方法的基本原理,并在克拉玛依油田某区块下克拉玛依组冲积扇扇中亚相的构型建模中加以应用,最终建立的三维构型模型较好地展现了平面上和垂向上的分布形态及各构型间的接触关系。

Abstract:

Through scaning training image, multiple-point geostatistics can obtain the correlation of multiple points and can well describe reservoir distribution form and regularity. It has better practicability than traditional two-point geostatistics that describe the correlation of two points with variogram. The paper introduced the algorithm theory of multiple-point geostatistics and applied this method in structure modeling of middle fan subfacies of alluvial fan of Lower Karamay Formation of a certain block in Karamay Oilfield. Through the algorithm, the 3D simulation result of structure modeling well performed the distributional pattern of the structure and touch relationship of all kinds of structures in horizontal and vertical.
