二氧化碳驱油采出液的管道集输研究

近年来,因CO_2驱油比传统水驱油具有更明显的技术优势,能很好地提高低渗透和超低渗透油田的采收率而得到广泛的应用。一来满足油田开发的工作需要,二来解决了二氧化碳的封存问题,对大气环境的保护有利。但CO_2驱采出液的性质发生诸多改变,加大了集输的难度,对管道也提出了更高的要求。

Pipeline Gathering And Transportation of Carbon Dioxide Drive

In recent years,carbon dioxide flooding has more obvious technical advantages than traditional water flooding.It can be widely used to improve the recovery of low permeability and ultralow permeability oil fields,In order to meet the needs of the development of the oilfield,the second is to solve the problem of carbon dioxide sequestration,which is favorable for the environmental protection of the atmosphere.However,there are many changes in the properties of the carbon dioxide flooding,which increases the difficulty of the collection and puts forward higher requirements for the pipeline.
