Although stochastic modeling methods can achieve multiple implementations of sedimentary microfacies model in dense well blocks, it is difficult to realize continuous convergence of well spacing. Taking the small high-sinuosity meandering river sediments of the third member of Quantou Formation in Songliao Basin as an example, a deterministic modeling method based on geological vector information was explored in this article. Quantitative geological characteristics of point bar sediments were analyzed by field outcrops, modern sediments, and dense well block anatomy. The lateral extension distance, length, and spacing parameters of the point bar were used to quantitatively characterize the thickness, dip angle, and frequency of the lateral layer. In addition, the three-dimensional architecture modeling of the point bar was carried out in the study. The established three-dimensional architecture model of well X24-1 had continuous convergence near all wells, which conformed to the geological knowledge of small high-sinuosity meandering river, and verified the reliability of this method in the process of geological modeling in dense well blocks.

基于地质矢量信息的致密井段点状杆构架建模-以松辽盆地泉头组三段为例

尽管随机建模方法可以在致密的井段中实现沉积微相模型的多种实现，但很难实现井距的连续收敛。以松辽盆地泉头组三段小高曲率蜿蜒河道沉积物为例，探讨了一种基于地质矢量信息的确定性建模方法。通过野外露头，现代沉积物和稠密的井眼块状解剖学分析了点状条带沉积物的定量地质特征。点杆的横向延伸距离，长度和间距参数用于定量表征横向层的厚度，倾角和频率。此外，在研究中对点栏进行了三维结构建模。
