摘要/Abstract

摘要：

三维地质建模应用于油田勘探开发的各个阶段，解决不同的问题时，对建模的规模、精度及要求也不同。分区块地质建模在井位部署、开发调整分析上可以起到一定的指导作用，但是各独立区块模型没有统一的标准，不能实现由小模型到大模型的拼接，制约了油田的整体勘探开发及规划工作。为了更好发挥地质建模在油田勘探开发全生命周期的精准作用，研究以渤海湾盆地整装孤岛油田为例，提出了油田—区块—储层单砂体构型的多级建模策略。使用具有自主知识产权的Direct、M³地质建模软件，应用地质约束的地质统计学及嵌入式储层构型建模方法，实现了从大到小、整体到局部、笼统到精细。分层级刻画了油田的构造沉积演化特征、储层内部构型及油藏空间展布，建成了中国首例油田级亿万网格节点的三维地质大模型及分级模型，为深化地质认识、油藏开发潜力评价、整体开发调整提高采收率提供了有利的手段。多级三维地质建模技术既为技术人员提供了多学科一体化的交流平台，又为油田勘探开发提供了方向，是油田数字化管理的有力抓手，更是数字化、智能化油田发展的必然趋势。

Abstract:

3D geological modeling is essential at every stage of oilfield exploration and development. The scale, precision, and requirements of modeling vary depending on the issues at hand. While zonal block geological modeling guides well location deployment and the analysis of well group development and adjustments, the absence of a unified standard for each independent block model hinders the integration of smaller models into larger ones. This limitation affects the overall exploration, development, and planning of the oilfield. To maximize the precision and guiding role of geological modeling throughout the entire lifecycle of an oilfield, this paper uses an integrated oilfield, Gudao Oilfield, in Bohaiwan Basin as a case study. It introduces a multi-stage modeling strategy that progresses from a monolithic oilfield to zonal blocks and finally to reservoir configurations（single sand bodies）. These approach using geological modeling software, Direct and M³, with independent intellectual property rights and applying geostatistics and embedded reservoir configuration modeling with geological constraints to realize the transformation from macro to micro, whole to local, and general to detailed, providing an in-depth description of the oilfield’s structural and depositional characteristics, reservoir configurations, and spatial distribution of oil reservoirs. The 3D geological large-scale model and hierarchical model of the first multi-billion grid nodes of the oilfield in China are built. Such detailed modeling aids in deepening geological understanding, evaluating the potential of developed oil reservoirs, and locating remaining reserves, thereby ensuring the oilfield’s sustained and stable production. 3D geological multi-stage modeling technology not only facilitates multidisciplinary communication among petroleum professionals but also serves as a robust foundation for digital oilfield management. It represents an inevitable trend towards the development of digital and intelligent oilfields and offers significant guidance for oilfield exploration and development.

Key words: oilfield grade, unit level, configurational level, 3D geological modeling, strategies and methods
