来自法国东北部阿尔贡地区国家实验室的最新研究表明,目前只有一小部分井下油水和气水分离器仍然在油田应用,这与该技术在20世纪90年代后期所做的预期相比,可谓大相径庭。井下油水分离器(DOWS)和井下气水分离器(DGWS)使所有采出水无需泵送到地面处理,而是直接在井下处理,节省了相关费用。JohnA.Veil和JohnJ.Quinn根据W31109Eng38合同,在2004年11月为美国能源部的国家能源技术实验室准备了题为“井下分离技术动态与地质状况的关系”的研究报告。
Recent research from the Argonne National Laboratory in northeastern France shows that only a small proportion of downhole oil-water and gas-water separators are still being used in the field, which is quite different from what the technology did in the late 1990s . Downhole oil-water separators (DOWS) and down-hole gas-water separators (DGWS) save all of the produced water from being pumped to surface treatment, but are processed directly downhole to save costs. According to W31109Eng38 contract, John A. Veil and John J. Quinn prepared a report entitled “The Relationship between the Dynamics of Underground Separation Technologies and Geological Conditions” for the U.S. Department of Energy’s National Energy Technology Laboratory in November 2004.
