【摘要】 储层构型参数库是储层地质知识库的重要组成部分，可为储层地质研究和储层地质建模提供关键的定量约束参数。然而，由于领域内术语和分类体系的不统一，国内外学者研究关注的尺度范围存在差异，以及文献数据的分散性，建立一个统一的、全面的储层构型参数库面临诸多挑战。本文提出了一种基于文献数据拾取的储层构型参数库构建方法，并以辫状河储层为例构建了一个储层构型参数库。首先设计了一个标准化的辫状河分类分级体系，并建立了统一数据结构的数据表，以支持多源数据的整合分析。随后采用数据拾取工具WebPlotDigitizer，提取专业文献中静态图表数据，成功建立了一个包含2589组构型单元的辫状河储层构型参数库，这一参数库不仅涵盖了辫流带、辫状河道、心滩、垂积体和落于曾等多种构型单元规模，还提供了相关地质背景信息。通过该参数库，本文对辫状河储层构型单元的几何特征进行了详细的统计分析。结果表明：(1)对辫状河沉积采用统一的分类分级方案并规定储层构型参数库的表结构，可将不同来源的数据整合在一起，以便进行不同来源不同地质背景下的储层构型单元几何参数的对比分析，实现对辫状河储层构型参数库的集中管理和应用；(2)采用基于WebPlotDigitizer工具的文献数据拾取方法，可将专业文献中静态的图表数字化，为储层构型参数库的建立提供丰富的数据源；(3)基于文献的数据拾取存在信息不完整和信息结构不统一的局限性，因此有必要面向储层地质研究和储层建模等需要，建立业界统一标准的储层构型参数库及其信息共享服务系统，以解决地质知识语义异构、来源众多、结构多样、时空尺度跨度大等问题。本文的研究不仅为辫状河储层构型几何特征的类比研究提供了数据基础和技术手段，还为其他类型储层(如三角洲和曲流河)的构型参数库建设提供了参考。更多还原

【Abstract】 A reservoir architectural parameter database(RAPDB) is an essential component of the reservoir geological knowledge base, providing critical quantitative constraint parameters for reservoir geological studies and reservoir geological modeling. However, due to the lack of uniformity in terminology and classification systems within the field, the differences in the scale of research focus between domestic and international scholars, and the scattered nature of literature data, constructing a unified and comprehensive reservoir architectural parameter database faces numerous challenges. This paper proposes a method for constructing a reservoir architectural parameter database based on literature data extraction and uses braided river reservoirs as a case study to construct such a database. First, a standardized classification and grading system for braided river reservoirs was designed, and a unified data structure was established to support the integration and analysis of multi-source data.Subsequently, the WebPlotDigitizer tool was employed to extract data from static figures and tables in professional literature,successfully building a braided river reservoir architectural parameter database consisting of 2,589 architectural elements. This parameter database not only includes the scale of various architectural elements such as braided belts, braided channels, bars,vertical accumulation bodies, and overbank deposits, but also provides relevant geological background information. Through this database, this paper conducts a detailed statistical analysis of the geometric characteristics of reservoir architectural elements in braided river reservoirs. The results indicate that:(1) Adopting a unified classification and grading scheme for braided river deposits and specifying the table structure of the reservoir architectural parameter database allows for the integration of data from different sources, enabling comparative analysis of geometric parameters of reservoir architectural elements from various geological backgrounds, and achieving centralized management and application of the braided river reservoir architectural parameter database;(2) The literature data extraction method using the WebPlotDigitizer tool can digitize static figures and tables in professional literature, providing a rich data source for building the RAPDB;(3) Literature-based data extraction has limitations of incomplete information and inconsistent information structure. Therefore, it is necessary to establish a unified standard RAPDB and its information sharing service system to meet the needs of reservoir geological studies and modeling, addressing issues such as semantic heterogeneity of geological knowledge, diverse sources, varied structures, and large spatiotemporal scale spans. This study not only provides a data foundation and technical means for analogous research on the geometric characteristics of braided river reservoir architecture but also offers a reference for the construction of architectural parameter databases for other types of reservoirs, such as deltas and meandering rivers.更多还原
