胡尖山长4+5油藏是典型的特低渗油藏,压裂改造是该类油藏开发获得工业油流的必须手段。为了避免传统压裂选井选层的经验性和盲目性,本文运用了灰色关联分析方法建立了适合该区压裂效果影响因素分析的数学模型,最后通过模型的实际运用具有很好的吻合性,为现场该类油藏压裂效果的影响因素评价提供了依据和指导。
The Hujianshanchang 4 + 5 reservoir is a typical ultra-low permeability reservoir. Fracturing rebuilding is a necessary means for the development of such reservoirs for obtaining industrial oil flow. In order to avoid the experience and blindness of the conventional fracturing well, the paper establishes a mathematical model which is suitable for the analysis of the influencing factors of the fracturing effect in this area by using the gray relational analysis method. Finally, it has a good agreement by the practical application of the model , Provided the basis and guidance for the evaluation of the influencing factors of the fracturing effect on the site.
