我国现已探明的63.2亿吨低渗透油藏原油储量,尤其是其中50%左右尚未动用的储量,运用二氧化碳驱比水驱具有更明显的技术优势。目前,世界上大部分油田仍采用注水开发,针对目前世界上大部分油田采用注水开发面临着需要进一步提高采收率和水资源缺乏的问题,国外近年来大力开展了二氧化碳驱油提高采收率(EOR)技术的研发和应用。这项技术不仅能满足油田开发的需求,
China has now proven oil reserves of 6.32 billion tons of low permeability reservoirs, especially about 50% of which have not yet been used reserves, the use of carbon dioxide than water flooding has more obvious technical advantages. At present, most of the world’s oilfields are still using waterflooding development. In view of the fact that most oilfields in the world currently use waterflooding development are facing the problem of further increasing oil recovery and lack of water resources, foreign countries have energetically carried out carbon dioxide displacement oil recovery in recent years (EOR) technology research and development and application. This technology can not only meet the needs of oilfield development,
