| 摘 要： | 本文以黄骅坳陷港西开发区为例，探讨在油田开发阶段，如何通过密井网区沉积微相定量几何学数据对新近系明化镇组沉积环境相似的稀井网区进行沉积微相三维建模的方法。密井网区研究表明，港西开发区河流相的单河道砂体宽度约50-300 m，一般为100-200 m，厚度约5-15 m，一般为6-10 m；漫溢砂体长、宽一般小于200 m；砂体结构主要为迷宫状和拼合板状两种型式。应用密井网区沉积微相定量几何学数据，采用标点过程方法，对井网较稀的目标研究区进行了三维沉积微相建模研究，并取得了良好的应用效果。

| Abstract: | Taking the Minghuazhen Formation of the Neogene in Gangxi Development area of Huanghua depression as an example, the paper is mainly focused on the method of sedimentary microfacies 3D modeling towards the area with a relatively sparse well network using the quantitative geometrical data obtained from the area with a dense well network with the similar sedimentary environment during the oilfield development stage. The result of the study on the area with dense well network shows that the width of the single channel sandbody ranges from 50 to 300 meters , generally from 100 to 200 meters, and the thickness ranges from 5 to 15 meters , generally from 6 to 10 meters. The length and width of the overflow sandbody are less than 200 meters. Jigsaw puzzle and labyrinth are the two main sand architecture types. Based on the quantitative geometrical data obtained from the dense well network area, we adopt the marked point process method, carried out 3D sedimentary microfacies modeling study for aiming at the target area with a relatively sparse well network, and achieved better effect. |
