摘要
目前我国油田以向油层注水保持油层压力来提高原油采收率为主要采油手段,所注水98%都是经处理达标后的油田采出水。活性炭纤维(ACF)是一种新型高效吸附材料,孔径分布窄,比表面积大,再生条件温和,并可以根据处理吸附物质的大小调整ACF的孔隙大小,使其作为精细过滤材料处理油田回注水具有可行性,可实现吸附和过滤同时进行,提高注水水质。
Injection of water is the main technique for oil extraction at present, and around 98% of the injected water is recycled. Activated carbon fiber（ACF） is a new kind of efficient adsorbent. Due to its special microporous structure and abundant surface functional groups, ACF can be feasible to be used as the fine filter material Filtration and adsorption can be realized at the same time, and improved the quality of injected water.
