    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。

    Abstract:

    As the oilfield with only 50 million-ton reserves that has been overall developed of SINOPEC during the 12th Five-Year Plan,Chunfeng Oilfield has established a strategic goal of building a million-ton oil production base within five years at the very beginning of its development. In view of the lack of effective reservoir description,development mode,engineering technology,management system,and other difficult problems in the efficient development of thin-shallow superheavy oil reservoir,targeted systemic researches were conducted centered on“three-new and three-high”mode. Eventually seven innovative key technologies were developed,technologies of two meters thin-shallow detailed reservoir prediction and high-efficiency thermal compound oil recovery have been developed to solve the problem of efficient production. Horizontal well sand-control plug-drilling-free integrated technology of drilling and completion,as well as horizontal pump integrated 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 multi·effect mechanical compression evaporation technology were improved to realize green and low-carbon development. Intelligent oilfield efficient management operation system was constructed to improve labor productivity and to reduce the development cost. Chunfeng Oilfield developed nearly 50 million tons of reserves and has established a stable oil production of million tons for four years from 2015 to 2018. The capacity construction investment and full cost per unit reduced by about one-third. While producing great economic and social benefits,these key technologies have enriched the theory and technology of heavy oil reservoir development. They have been applied in Xinjiang,Henan,East Shengli and other similar oilfields in China,and support the scale profitable development of low grade super-heavy oil reservoir.
