通过对储集层压裂改造,可以达到改善产能效果的目的。通常采取井温测井方法来分析压裂效果,定性评价裂缝高度,但此方法受诸多因素的影响,难以精确确定裂缝高度。采用同位素示踪测井方法,不但可以分析压裂效果,还能定量评价压裂裂缝的高度,从而弥补了常规测井方法评价压裂效果的局限性和不足。

Usually fracturing can improve the productivity of the reservoirs ,well temperature logging is used conventionally to analyze fracturing result and evaluate fracturing height qualitatively.But this method is affected by many factors that it can’t determine the fracturing height accurately. This article will introduce a way to use isotope tracer log replacing temperature logging ,which not only can analyze fracturing result but also evaluate fracturing height quantitatively. This makes up conventional limitation and defect greatly.
