摘　　要：以长庆安塞油田王窑中西部长6特低渗裂缝型C井区和孔隙-裂缝型A井区注水油藏为例,利用现有的试井资料分析研究,成功地进行了油水井渗透率平面变化特征、渗透率、表皮系数、地层压力随时间动态变化特征的定性、定量分析。本文方法和结果已进一步用于低渗各类型注水油藏的井间连通情况、分析注采平衡、判断渗流特性,为合理选择注水时机、强度提供依据。Taking examples of Changqing Ansai oilfield Wangyao middle west Chang6 special low permeability fracture style of C well area and pore-fracture style of A well area water flood reservoir,using the present well testing material to analyze and study,qualitative and quantitative analysis for dynamic change characteristics of the oil water well permeability plain change characteristic,permeability,skin factor,layer pressure with time is conducted successfully. The method and result in this paper have been further applied in well connection situation of all kinds of low permeability of flood water reservoir,analyzing flood water production balance,judging permeability characteristic,and which provides basis for reasonable selecting flood water time and its strength.
