摘要
大庆油田从“七五”开始加大了三次采油提高采收率的现场试验研究力度，先后开展了聚合物驱、CO2驱、三元复合驱、泡沫复合驱、聚表剂驱等多种提高采收率技术的现场试验。聚合物驱油技术于“九五”初期开始工业化应用，目前三元复合驱也已进入了工业化推广应用阶段。为确保三次采油现场试验及工业化的顺利实施，地面工艺技术的研究与驱油试验同步开展，并随着驱油技术的不断发展和完善，形成了适合大庆油田不同三次采油方法现场试验和工业化推广应用的地面工艺配套技术。
During the seventh ＂Five-Year Plans＂, Daqing oilfield began to increase the efforts in field testing research on tertiary oil recovery to increase recovery factor, with multi EOR technologies being successively implemented, including polymer flooding, CO2 flooding, ASP flooding （Alkaline-Surfactant-Polymer Flooding） , foam combination flooding, polymer-surfactant flooding and so on. Polymer flooding technology was started to be put into commercial application during the ninth ＂Five-Year Plans＂, and the ASP flooding has presently entered into commercially extended application stage. The surface technology research and the displacement test were simultaneously implemented to ensure the success of the field test and the commercialization of tertiary oil recovery technology, and with the development and improvement of oil displacement technology, surface auxiliary technology that is suitable for field test and commercial extension of various tertiary oil recovery technologies in Daqing Oilfield has been formed.
