摘　　要：近年来,得益于深层大型碳酸盐岩气藏与页岩气勘探开发的重大突破,四川盆地已成为我国目前最具发展潜力的含油气盆地。位于该盆地中部的安岳气田是我国迄今已发现的最大的整装碳酸盐岩气藏,也是我国近年来发现的最重要的特大型气田,但该气田也存在着储层孔隙度低、渗透率低,气层薄且纵横向分散、非均质性强,构造幅度极低且气水关系复杂等重大难题,使得天然气储量向产量的快速转化面临着巨大的挑战。为此,通过持续技术攻关,创新集成了多项关键技术,并在多个方面取得了重大突破:①创新形成特大型古老复杂碳酸盐岩气藏精细开发技术,构建“透明气藏”,建立高产井培育技术,实现了下寒武统龙王庙组气藏开发口口井高产、下震旦统灯影组气藏单井天然气产量大幅度提高,保证了该气田长期高产稳产;②集成创新大型气田优快建设技术,实现了气井全生命周期安全受控,3年高效建成精品工程,打造绿色矿山新高地,高效建成安全清洁大气田;③集成创新特大型气田开发智能管控技术,实现了万物互联、深度感知和自动化生产,融合AR、VR、机器人、无人机等新一代智能技术,开辟了气田开发智能化管理新形态,打造智能气田;④创新形成特大型气田整体开发优化技术,显著提升了强非均质性气藏的开发效果,确保了特大型有水气藏的长期稳产。该研究成果可以为国内外类似气田的高效开发提供借鉴。In recent years,the Sichuan Basin has been the most potential hydrocarbon-bearing basin in China thanks to the great exploration and development breakthroughs of deep large integral carbonate gas reservoirs and shale gas in this basin.The Anyue Gas Field located in central Sichuan Basin is not only the largest carbonate gas reservoir,but the most important supergiant gas field discovered in China in recent years.However,it faces a series of major difficulties,e.g.low reservoir porosity,low permeability,low gas well productivity,thin and vertically and laterally disperse gas layer,strong heterogeneity,quite low structural amplitude and complicated gas–water relationship,which bring great challenges to the rapid conversion of natural gas reserves to production.In this regard,technical researches have been carried out continuously.As a result,many key technologies have been innovatively integrated and great breakthroughs have been realized in many aspects.First,fine development technologies for supergiant,ancient and complex carbonate gas reservoirs are developed innovatively,"transparent gas reservoir"is constructed and the technologies for cultivating high-yield wells are established.By virtue of these technologies,all development wells in the gas reservoir of Lower Cambrian Longwangmiao Formation reach the target of high yield and the single-well gas production rate of the gas reservoir of Lower Sinian Dengying Formation is increased significantly,which provides support for the long-term high production and stable production of Anyue Gas Field.Second,good and fast construction technologies for large-scale gas fields are innovatively integrated.Based on this,the safety of gas wells is under control in the whole life cycle,quality engineering is built up efficiently within 3 years,green mining areas are forged and large-scale safe and clean gas fields are built up efficiently.Third,intelligent control technologies for the development of supergiant gas fields are innovatively integrated.By means of these technolog
