摘　　要：长庆油田三边地区延长组储集层油水关系复杂,流体性质识别难度较大。应用传统的气测录井图板解释符合率较低,迫切需要加强解释评价方法的研究。为了探讨能有效识别延长组储集层流体性质的方法,收集了该区内24个已获试油验证储集层的气测录井资料,构建全烃峰基比、充注系数和能量系数3个参数,绘制重-中烃比率和轻-中烃比率交会曲线,建立解释图板和解释评价标准,系统地开展了定性与定量评价。现场应用实例证明,这种解释评价方法在该区应用效果较好。The oil-water relationship in the reservoirs of Yanchang formation in Sanbian area of Changqing Oilfield is complex and it is difficult to identify the fluid properties.It is urgent to strengthen the research of interpretation and evaluation methods because of the low coincidence rate of the traditional gas logging chart interpretation.In order to explore the method of effectively identifying the reservoir fluid properties of Yanchang formation,the gas logging data of 24 oil tested and verified reservoirs in this area are collected,three parameters of total hydrocarbon peak value to base value ratio,filling coefficient and energy coefficient are constructed,and the curves of heavy-medium hydrocarbon ratio and light-medium hydrocarbon ratio are plotted.The interpretation chart and interpretation-evaluation criteria are established,and the qualitative and quantitative evaluation is carried out systematically.The field application shows that this interpretation and evaluation method is effective in this area.
