摘要
在过去60多年里,稠油开采工艺逐步完善,国内外关于不同的井网设计、操作条件和采油工艺的专利文献十分丰富。其中蒸汽吞吐和蒸汽辅助重力泄油自提出已有30多年的历史,目前尚有一些新的技术正在研究和评价当中。文章系统的介绍了采用不同驱动剂使稠油流动及其相关的开采工艺。通过分析,得到了稠油开采技术的演变,以及获得经济采收率的技术特点。结果揭示了稠油开采工艺从酝酿到提出,再到实现的一些特点,为国内稠油开采提供了依据。
Over the past 60 years,recovery methods for heavy oil reservoirs have evolved and the patent literature is rich with different well designs,operating conditions,and recovery mechanisms.Cyclic steam stimulation and steam-assisted gravity drainage are now three decades old since invention and at this point there are a few new technologies on the table which are being researched or evaluated.Here,the passage illustrate various agents used to mobilize heavy oil and bitumen and recovery processes associated with the agents.An analysis has been done to understand the evolution of in-situ oil sands recovery technology and what features have enabled economic recovery oil sands resources.The results reveal that a small number of features arising from the oil sands recovery process ideas dreamed,proposed,and developed over the past 60 years,which provide the guidance for domestic heavy oil recovery.
