合成声波测井法在裂缝预测中的应用

On the Application of Seislog Method in Fracture Prediction

合成声波测井法用于碳酸盐岩油藏裂缝发育及分布特征预测非常有效。只要有断层或裂缝发育,地层就会变得疏松,在测井剖面上就表现为孤立﹑不连续的低速异常体。结合油田生产实例,运用此方法预测裂缝的平面分布情况,结果与工区的生产情况以及地质特征吻合。

The paper formulates the methodic theory and processing flow of Seislog used in fracture prediction.Seislog is valuable to predict the fracture development and distribution features for carbonate rock reservoirs.Seislog is used in WJ—MY Dan,a village oil deposit,to predict the fracture＇s plane distribution condition.The result fits the production and geologic features in the work area.It shows that the Seislog can be popularized in fracture distribution prediction in the work area.
