辽河油田稠油蒸汽驱和SAGD集输与处理工艺技术

Heavy Oil Steam Flooding and SAGD Technologies in Liaohe Oilfield

辽河油田稠油主要开采方式是蒸汽吞吐开采,近年来,稠油蒸汽驱开采和SAGD(蒸汽辅助重力泄油)开采也得到了工业化应用,在蒸汽吞吐基础上大幅度提高了采收率,为辽河油田稳产奠定了坚实的基础。辽河油田齐40块蒸汽驱实现了中深层稠油蒸汽驱开采,在同类型油藏规模实施蒸汽驱开发方面处于领先地位;辽河油田曙一区杜84块SAGD开发在国内尚属首次。目前,辽河油田已形成一整套成熟可靠的稠油、超稠油蒸汽驱开采和SAGD开采地面集输与处理工艺技术,并在稠油区块得到了全面的推广和应用,具有广阔的发展前景。

The traditional soaking by steam stimulation technology was mainly adopted in the exploitation of heavy oil in Liaohe oilfield. In recent years,steam flooding and SAGD(Steam Assisted Gravity Drainage)technologies were industrialized and the recovery efficiency was greatly improved,which laid a solid foundation for the stable production of Liaohe oilfield. The exploitation of heavy oil steam flooding in middle-deep strata was realized in qi40 block,Liaohe oilfield,which maintained the leading position. The SAGD development of du84 block of shu1 area was realized in Liaohe oilfield,which was the first time in China. A set of steam flooding and SAGD surface gathering and processing technologies for the heavy oil and super heavy oil were formed in Liaohe oilfield.
