摘　　要：长庆安塞油田属典型特低渗透油田,单井产量低,为此,建立了一套有效的低渗透油田采油工艺配套技术,在新技术的引进、新试验的基础上,对适用技术的推广、完善,取得了显著的成效,其油井检泵周期由2004年的430天延长到2006年的484天,平均抽油泵效由29%上升至41%。Ansai Oilfield of Changqing belongs to typical very low permeability oilfields with low output of single well. The authors have developed a set of effective oil production technology for low permeability oilfields, which gains notable effects in promoting and perfecting practical technology on the basis of new technology introduction and new tests. What＇s more, by this technology, the period of checking pumps is prolonged from 430 days in 2004 to 484 days in 2006, and the average pump-out efficiency is increased from 29% to 41%.
