用熵权系数法优选压裂井

Using Entropy Weight Coefficient Method to Optimize the Choice of Fractured Well

基于熵权系数法,选取有效厚度、目前含水饱和度、微构造和流动单元类另q四个主要参数,用油田最近时期已压裂井建立了压裂井层优选预测模型。并利用该模型对油田压裂井效果进行预测,预测结果符合现场实际施工,说明利用该预测模型进行压裂效果评价是有效、可行的。

Based on entropy weight coefficient method, by selecting four main parameters including net - pay thickness, current water saturation, microstructure, and flow unit, a optimized forecast model of fractured wells has been built by use of the latest fractured wells in the oilfield. The fracturing effect in the oilfield has been forecasted by use of the model. The results are consistent with the actual operations, which show it is effective and feasible to use the model to evaluate fracturing effect.
