基于欧式贴近度的压裂效果评价方法在姬塬油田的应用

Application of Fracturing Effect Evaluation Method Based on Euclid Approach Degree in Jiyuan Oilfield

影响压裂井压后产液量的因素很多,各个因素关系复杂并且存在一定的联系。本文中综合考虑影响压后产液量的多种因素,采用基于欧式贴近度的压裂评价方法,来分析压后产液量的主要影响因素并给出权重,可对压裂井压裂效果按从优到劣进行排序,以此来判断压裂井压裂效果的好坏。该方法经矿场验证,对压裂油井产液量的影响具有参考意义。

There are many factors to affect liquid production of fractured wells after fracturing.The relationship of these factors are complex and they are connected each other.In the article,many factors to affect liquid production were considered,the fracturing evaluation method based on Euclid approach degree was used to evaluate these factors,their weights were gained,by which the effectiveness of fractured wells can be ranked from good to bad.This method has been tested in oil field and good result has been gained.
