中东地区EOR现状、潜力和未来发展趋势

EOR IN MIDDLE EAST: CURRENT,POTENTIAL AND FUTURE DEVELOPMENT TREND

近年来中东地区一些国家因易采原油储量不断减少,大力推行EOR项目。阿曼、伊拉克和科威特等国家在不同类型油藏先后开展了EOR的研究和应用,包括聚合物驱、表面活性剂驱、蒸汽驱和二氧化碳驱等,其中聚合物驱发展到全油田规模。先进的二次采油技术仍然是中东地区主要的采油技术,以沙特阿美公司为代表,改进油藏管理模式,实施智能完井技术、千兆网格模拟技术、智能水驱技术和新兴监测技术,取得良好效果。EOR项目具有很大潜力,但从概念落实,生成实验数据模拟研究,到第一个矿场试验实施,再到全面商业化推广需要很长的一段时间,而且面临着成本高、研发人员短缺和油价低等问题,未来发展之路还很长。

In recent years,due to the continuous lack of the easy-to-produce oil reserves for some countries in the Middle East,EOR projects have greatly promoted. The EOR researches and their applications were conducted in different kinds of the oil reservoirs in Oman,Iraq,Kuwait and so on,including polymer flooding,surfactant flooding,steam flooding,CO2 flooding and so forth,the former has developed and generalized to the whole oilfield. The advanced secondary recovery（ ASR） is still the principal oil producing technique in the Middle East,taking Saudi Aramco as the representative,the model of oil reservoir management was improved,the intelligent well completing technique,kilomega-net simulating technique,intelligent water flooding technique and newly developed monitoring technique have achieved much better effects. The EOR projects possess a great potential,but it is required a long time for the projects from the concepts,experimental data obtaining and simulation study to their application of the first field pilot test,and moreover to the overall commercialized generalization,and furthermore the following problems are meeting： higher cost,short of the developing staff,lower oil price,there is still a long way to go.
