摘要
可压裂性指标是决定后期是否进行储层改造的重要评价参数,考虑单一因素如脆性指数难以真实反映储层的压裂难易程度,本文从地质和工程角度出发,研究总结了不同因素对页岩可压裂性的影响。引入模糊层析分析法,建立了综合评价方法,应用实践表明该方法具有较高的正确性。
Fracability is the capability of the shale that can be effective fractured and is an important evaluation parameter to determine the late reservoir stimulation.Considering that a single factor such as brittleness index is difficult to reflect reservoir fracturing,in this paper we summarized the influence of different factors from geology and engineering perspective and a model of a comprehensive evaluation is further established based on fuzzy chromatography analysis method.Application practice show that this method has higher accuracy.
