摘　　要：随着全球油气资源供需矛盾的日益突出和常规油气资源的不断减少,通过复杂结构井降低成本提高油气采收率已成为石油工业的必然趋势。极大储层接触技术是在最大储层接触技术基础上发展起来的一种能提高油藏采收率的新技术,它比最大储层接触技术更加智能,难度也更大。为此,在国内外相关文献调研的基础上,从油藏地质和工程相结合的角度将现有最大储层接触技术与新型智能完井技术相结合,提出了极大储层接触技术的关键技术。主要为:油藏精细描述与剩余油分布预测技术、布井方案优化技术、井眼轨迹优化设计与控制技术、储层保护技术、膨胀管与先进封隔器技术、ERC智能完井技术等。还建议国内研究者在理论、技术、装备、工具等方面尽早准备。With the contradiction between supply and demand of the global oil and gas resources being increasingly prominent and conventional resources being reducing,it has become an inevitable trend that reducing cost and EOR through complex structure wells around petroleum industry.Extreme reservoir contact(ERC) is a new EOR technology developed on the basis of maximum reservoir contact(MRC),and more intelligent and difficult than MRC.Based on related literature at home and abroad,this article combined the MRC technology and new intelligent system to the key technologies of ERC from the perspective of reservoir geology and engineering,mainly including reservoir fine description and the remaining oil distribution prediction technology,well placement optimization technology,the wellbore trajectory optimization design and control technology,formation protection technology,expansion pipe and advanced packer technology and ERC intelligent completion technology,etc.This article also suggested that domestic researchers prepared theory,technology,equipment and tools for ERC technology as soon as possible.
