摘要：

以克拉玛依油田六中东区下克拉玛依组为例，通过对8口小井距的密闭取心井及周围24口井的构型特征分析，建立了研究区目的层段的三维构型模型。分析得到冲积扇不同亚相实用的构型建模方法：冲积扇扇根为泛连通体，各级构型展布范围不大，主要为片流砂砾体，三维构型建模适合用基于目标的模拟方法；扇中主要构型单元为漫流细粒、辫流水道和漫流砂体，辫流水道与漫流砂体有明显的接触分带关系，适合用截断高斯模拟方法；扇缘主要构型单元为漫流细粒，少量分布径流水道和漫流砂体，适合用序贯指示及基于目标的模拟方法。最终建立的三维构型模型能较好地体现了各级构型单元在平面上和垂向上的展布范围和接触关系。为后期剩余油分布的预测、井网调整及剩余油挖潜提供了准确的依据。

Abstract:

This paper is a case study on the Lower Karamay Formation. By analyzing eight sealed coring wells with small distance and the architecture characteristics of twenty-four wells around, a 3D architecture model of target formation of the study area is built. Different architecture modeling methods practical to fans with different subfacies were derived. Fan head is extensive connecting body mainly composed of sheet-flow sandstone bodies, and the distribution areas of the architecture of different levels are small, so Object-based modeling method is used. The main architecture units of mid-fan are fine sheet-flow grains, braided channel and sheet-flow sandstone body.The braided channel and sheet-flow sandstone bodies have obvious contact belt. So Truncate Gauss Simulation method is used. The main architecture unit of the fan-margin is fine sheet-flow grains, as well as a small number of through-flow and sheet-flow sandstone bodies, so Sequence Indicator Simulation and Object-based modeling method are applicable. The 3D architecture model built can well embody the distribution areas and the contact relations of the architecture units of different levels in both horizontal and vertical directions, which can provide an evidence for the remaining oil prediction, as well as well-pattern adjustment and remaining oil tapping.

Key words: alluvial fan, architecture modeling, Truncate Gauss Simulation, Object-based modeling, Sequence Indicator simulation
