摘要

苏里格气田作为中国致密砂岩气田的典型代表，历经20余年规模效益开发，已进入稳产与提高采收率阶段。面对富集区剩余气“碎片化”、低丰度区储量“劣质化”、富水区开发“难动用”以及低产低效井“治理难”等关键挑战，系统剖析了制约苏里格气田长期稳产与提高采收率的关键问题：①致密储层多尺度构型对剩余气分布的控制作用；②多层系立体开发中的应力场—压力场—流动场耦合机制；③复杂气水关系下微观渗流与宏观动用规律；④全生命周期生产动态智能诊断与优化控制。围绕这些问题阐述了储层构型表征与剩余气挖潜、立体井网协同动用、富水区避水开发、低产井数智化治理等方面的核心技术。针对目前阶段气田开发技术仍存在的不足，认为未来应在“数字孪生气藏”构建及剩余气精细挖潜、基于地质—工程一体化的多层系立体开发、微观渗流定量表征与控水增气材料研发、智能开发管控平台搭建等重点领域开展技术攻关。

Abstract

As a typical giant tight sandstone gas field in China

Sulige gas field has entered a stage of long-term stable production and enhanced gas recovery (EGR) after more than 20 years of large-scale commercial development. In response to critical problems

including the fragmentation of remaining gas in enriched zones

the deterioration of reserves in low-abundance zones

the difficulty of mobilizing resources in water-bearing zones

and the challenges in managing low-yield and low-efficiency wells

this study systematically examines the key issues constraining the long-term stable production and enhanced gas recovery of Sulige gas field:(1) the controlling effects of multi-scale reservoir architecture on the distribution of remaining gas; (2) the coupling mechanisms of stress

pressure

and flow fields in the three-dimensional development of multi-layer reservoirs; (3) the mechanisms of microscopic flow and macroscopic reserve utilization under complex gas-water relationships; and (4) intelligent diagnosis and optimal control of production dynamics throughout the full life cycle. Centering on these issues

the paper proposes the core technologies for reservoir architecture characterization and remaining gas recovery

synergistic production through three-dimensional well-pattern development

water- avoidance production in water-rich zones

and intelligent management of low-yield wells. To address the current limitations of gas field development technologies

future efforts should strive to make breakthroughs in key areas including the construction of digital twin system of gas reservoirs and fine-scale recovery of remaining gas

multi-layer three-dimensional development based on geology-engineering integration

quantitative characterization of microscale flow and development of water-control and gas-enhancement materials

and the establishment of intelligent development and management platforms. This study aims to provide theoretical guidance and technical support for enhanced gas recovery in the Sulige giant tight sandstone gas field

serving as a reference for the efficient development of other tight sandstone gas reservoirs under similar geological conditions.
