摘要:

河流相是世界范围内十分重要的储层类型之一,占我国已探明和投入开发的陆源碎屑岩储层储量的42.6%,曲流河是已开发的河流相储层的主体,多级次沉积构型表征是高含水油气田剩余油气挖潜和非常规油气藏规模效益开发的关键。近30多年来,在曲流河沉积构型模式、构型表征与建模方法、构型在油气田开发中的应用等方面取得了重要进展:(1)基于野外露头、现代沉积等原型模型研究,深化了河道及内部构型单元沉积演化机理,建立了河道带、点坝及侧积体分布样式及定量构型模式;(2)形成了多井模式拟合、智能化井震融合等构型表征方法,探索了多点地质统计学、基于单砂体构型界面和人工智能等构型建模方法;(3)分析了曲流河多级次构型对海上大井距油田开发选区、高含水油气田剩余油气挖潜、非常规油气藏水平井部署及轨迹优化等方面的重要指导意义。未来有必要对不同类型的曲流河构型模式与形成机理、地质知识与井震数据双驱动的曲流河沉积构型智能表征与建模技术等进行更为深入研究,为油气田高效开发提供理论指导与技术支撑。

Abstract:

Fluvial facies constitute one of the major reservoir types globally, accounting for 42.6% of the proven and developed reserves in terrestrial clastic reservoirs in China, with meandering rivers representing important components. Multi-scale sedimentary architecture characterization plays a critical role in unlocking hydrocarbon potential in high water-cut oilfields and facilitating the large-scale, efficient development of unconventional reservoirs. Over the past three decades, significant progress has been made in understanding meandering river sedimentary architecture models, improving characterization and modelling techniques, and elucidating the role of reservoir architecture in oilfield development. (1) Based on prototype model studies of outcrop successions and modern sediments, the depositional evolution mechanisms of channels and their internal architectural elements have been further elucidated, including establishing qualitative and quantitative architectural models for channel belts, point bars, and lateral accretion sandbodies. (2) Various architectural characterization methods have been developed, including multi-well correlation and intelligent well-to-seismic integration. Additionally, reservoir architecture modelling approaches have been explored using multiple-point statistics, bounding surfaces of single sandbody architecture, and artificial intelligence (AI). (3) The multi-scale architectures of meandering river successions provide important guidance for development of offshore oilfields with large well spacing, enhancing remaining hydrocarbon recovery in high water-cut oilfields, and optimizing horizontal well placement and trajectory design in unconventional reservoirs. Future research should deepen the mechanistic understanding of architectural models across different meandering river types and advance intelligent characterization and modelling techniques for meandering river sedimentary architectures, integrating geological knowledge with well-seismic data. This will offer theoretical and technical support for the efficient development of oil and gas fields.
