摘　　要：对于已注水开发多年,尤其是多次采取增产增注措施后的油藏,如何准确地判定低渗透非均质储集层渗流特征及其变化,难度很大。应用试井技术能够有效地认识这些特征和变化情况,为治理和改造油藏提供依据。分析准东沙南油藏经注水和措施改造使储集层的渗流特征产生的变化,有助于指导油藏的稳产、高产。It is difficult to properly determine the percolation and variation of low permeability and heterogeneous reservoir that has been developed by water flood process for many years and especially conducting several stimulations.Applying the well test technique can effectively identify such percolation and variation,and provide basis for the reservoir management and reformation.The case study from Shanan reservoir in eastern Junggar basin shows that the feature of such a reservoir has been changed a lot by many-year waterflooding and stimulations,effective analysis of these variations can help to correctly recognize and evaluate this reservoir,thus guide the stable and high production of it.
