摘　　要：随着安塞油田低渗透油藏逐渐进入中高含水期，受井筒状况日益复杂、小水量注水、以压裂投注为主等因素影响，在多年开发过程中，逐步引进同位素注入剖面测试、脉冲中子氧活化水流测试及相关流量精细注入剖面测试技术、从技术原理及现场应用效果等方面评价了各测试技术的适应性，为后期优选测试技术及老油田注水调整、措施挖潜等提供了依据．With the low permeability reservoirs of Ansai Oilfield gradually entering the mid-to-high water-cut stages, affected bv many factors such as increasingly complex wellbnre situations, a small amount of water injection, starting waterflooding with fi＇acturing as dominant and other factors, techniques of isotope injection profile testing, pulse-neutron oxygen-activation water-flow testing, and fine injection profile test for related flow are gradually introduced for many years of development process. The suitability of all the testing techniques is evaluated from aspects of the technical principles and field application effects. It provides the basis for selection of testing technology at the later period, adjustment of waterflooding the old oilfiehl, and taking measures to tap the potential.
