摘　　要：针对青海油田复杂储层"薄、多、散、杂、断层发育、低孔低渗"等特点,常规固体同位素五参数法在许多注水井特别是低流量注水井往往不能达到预期的效果。利用示踪相关流量测井技术,通过纵向上划分不同测量单元,采用连续追踪、重复测井工艺,根据实际测井曲线的形态特征、选取合适的读值方法和校正系数准确求取水流速度,可以提高该类油藏低流量注入剖面测井的准确性和可靠性。In consideration of the characteristics of reservoirs with 'thin,variety,scattered,miscellaneous properties,and properties of fault development and low porosity and low permeability' in Qinghai Oilfield,conventional five-parameter method by using solid isotope in injection wells especially in many low-flow injection wells often could not achieve the desired purposes.In this paper,a log technology by tracing correlation fluid flow is used through longitudinal partition in different measurement units,continuous track,repeating logging.Based on the actual logging curve characteristics,the appropriate method of reading and correction coefficients is selected for obtaining accurate flow velocity,the accuracy and reliability of the reservoirs can be improved.
