随着石油勘探开发技术的发展,尤其是近年来提高石油采收率(EOR)新技术的采用,油田化学剂在石油工业中的重要性日益增加。EOR技术所获得的原油日产量,仅就美国而言,己自1980年的53000立方米跃升至1984年的73300立方米,在原油总产量中所占的比重达到了5.3％。预计EOR技术的采油量仍将进一步增长,1990年将超过15.9万立方米/天,而2000年将趋近31.8万立方米/天,且EOR技术的累积产油量可达47.9亿立方米。EOR技术对油田化学剂的需求量十分可观,据目前的统计,每采出一立方米原油需消耗的化学剂数量不少,表面活性剂-聚合物驱油法:57—114公
With the development of oil exploration and development technology, especially the adoption of new technologies of increasing oil recovery (EOR) in recent years, the importance of oilfield chemicals in the petroleum industry is increasing day by day. The daily output of crude oil obtained by EOR technology, for the United States alone, jumped from 53,000 cubic meters in 1980 to 73,300 cubic meters in 1984, accounting for 5.3% of the total crude oil output. EOR technology is still expected to see further oil production growth, exceeding 159,000 cubic meters / day in 1990 and 318,000 cubic meters / day in 2000, with cumulative EOR production of 4.79 billion cubic meters. EOR technology has a significant demand for oilfield chemicals. According to the current statistics, a large number of chemicals are consumed per cubic meter of crude oil. The surfactant-polymer flooding method is 57-114 km
