摘要(Abstract):

稠油热采技术作为一种高能耗、高排放的能量集约型技术,在低碳时代面临巨大挑战。基于前人研究成果,系统总结了蒸汽吞吐、蒸汽驱、SAGD (蒸汽辅助重力泄油)、火驱共4项稠油热采主体技术,围绕注采模式优化、井网井型创新、工艺创新和多介质辅助提效等方面,回顾总结了稠油热采技术进展、技术特征及面临的挑战,结合生产需求提出创新发展策略。结果表明:在低碳背景下,针对能耗大、排放高、热波及不均匀和驱油效率低等关键问题,稠油热采技术应从2个方面寻求突破。(1)从机理认识和工艺创新方面协同发力,发展流体转向智能控制技术,大幅提升热能利用效率和采收率;(2)转变传统热能供应方式,发展地下生热和清洁绿色低耗开采技术,从能量供给端和利用端协同攻关,推动热采技术的可持续发展和提高低碳时代的技术适应性。研究成果可为稠油开发技术突破和可持续发展提供借鉴。
As an energy-intensive technology characterized by high energy consumption and high emissions, heavy oil thermal recovery technology face ssignificant challenges in the low-carbon era. Based on previous research achievements,4 main techniques for heavy oil thermal recovery are systematically summarized, including cyclic steam stimulation, steam flooding, SAGD(gravity oil-drainage assisted steam flooding) and in-situ combustion.Fo-cusing on the optimization of injection-production pattern, innovation in well patterns and well types, process inno-vation and multi-media-assisted efficiency improvement, the progress, technical characteristics and challenges of heavy oil thermal recovery technology are reviewed and summarized, and innovative development strategies are proposed combining with production needs. The results show that in low-carbon context, aiming at the key problems of high energy consumption, high emissions, uneven thermal sweep and low oil displacement efficiency, heavy oil thermal recovery technology should seek breakthroughs from 2 aspects:(1)collaborative efforts are madein mecha-nism understanding and process innovation to develop intelligent fluid diversion control technology, significantly improving thermal energy utilization efficiency and recovery rate.(2)The traditional thermal energy supply methods are transformed by developing underground heat generation and clean, green and low consumption extraction tech-nology, with combined research onboth the energy supply and utilization ends, so as to promote the sustainable de-velopment of thermal recovery technology and improve the technical adaptability in the low-carbon era.The research provides references for breakthroughs and sustainable development of heavy oil development technology.
