|
摘要
春风油田作为中国石化"十二五"期间唯一投入整体开发的五千万吨级储量油田,开发伊始即确立了用5年时间建成百万吨原油生产基地的战略目标。针对浅薄层超稠油油藏高效开发缺乏有效的储层描述方法、开发方式、工程技术以及管理体系等难题,围绕"三新三高"模式,开展针对性的系统攻关,创新配套了7项关键技术,突破了2m浅薄储层精细预测、高效热力复合采油技术,解决了有效动用难题;配套了水平井防砂免钻塞钻完井一体化、注汽水平泵采油一体化技术,解决了高效开发难题;完善了高干度循环流化床环保锅炉、产出水低温多效机械压缩蒸发技术,实现了绿色低碳发展;构建了智能油田高效管理运行体系,大幅度提高了劳动生产率,降低了开发成本。春风油田共动用地质储量近5 000万吨,2015—2018年连续4年稳产超过100万吨,产能建设投资及单位完全成本降低了1/3左右,在产生了巨大经济社会效益的同时,形成的关键技术丰富了稠油开发理论与技术,并已推广应用到新疆、河南以及胜利东部等同类型油田,支撑了低品位超稠油油藏的规模效益开发。
As the oilfield with only 50 million-ton reserves that has been overall developed of SINOPEC during the 12 thFive-Year Plan,Chunfeng Oilfield has established a strategic goal of building a million-ton oil production base within fiveyears at the very beginning of its development.In view of the lack of effective reservoir description,development mode,en-gineering technology,management system,and other difficult problems in the efficient development of thin-shallow super-heavy oil reservoir,targeted systemic researches were conducted centered on"three-new and three-high"mode.Eventual-ly seven innovative key technologies were developed,technologies of two meters thin-shallow detailed reservoir predictionand high-efficiency thermal compound oil recovery have been developed to solve the problem of efficient production.Hori-zontal well sand-control plug-drilling-free integrated technology of drilling and completion,as well as horizontal pump in-tegrated technology of steam injection and oil production were proposed to solve the problem of effective development.High-dryness circulating fluidized-bed environmental protection boiler,as well as produced water low-temperature multieffect mechanical compression evaporation technology were improved to realize green and low-carbon development.Intelli-gent oilfield efficient management operation system was constructed to improve labor productivity and to reduce the devel-opment cost.Chunfeng Oilfield developed nearly 50 million tons of reserves and has established a stable oil production ofmillion tons for four years from 2015 to 2018.The capacity construction investment and full cost per unit reduced by aboutone-third.While producing great economic and social benefits,these key technologies have enriched the theory and tech-nology of heavy oil reservoir development.They have been applied in Xinjiang,Henan,East Shengli and other similar oil-fields in China,and support the scale profitable development of low grade super-heavy oil reservoir.
