摘要：

近年来水力压裂在西湖低渗储层的应用逐渐增多.开展海上低渗储层压裂效果的主要影响因素研究,对西湖压裂选井选层研究及压裂改造设计具有重要指导意义.通过灰色关联法和模糊曲线法两种数学方法分析了西湖低渗储层压裂效果的主要影响因素,结果表明试验区压裂效果主要影响因素为试井渗透率,表皮系数,地质储量,加砂强度,孔隙度和有效厚度.两种分析方法得到的各影响因素排序位置略有差异,但得出的各因素对压裂效果的影响程度总体趋势一致,因此本研究所确定的压裂效果主要影响因素是合理的.

Abstract:

Hydraulic fracturing has found more and more applications in low permeability reservoir of Xihu oil and gas field in recent years. It is of great guiding significance to the selection of well and layer for fracturing and fracturing design to study the main factors affecting the fracturing result in low permeability reservoir in offshore oil field. We analyze such factors through gray correlation method and fuzzy curve method. The results show that the main factors affecting the fracturing result in the test areas are well testing permeability, skin factor, geological reserves, sanding strength, porosity, and effective thickness. The two analysis methods lead to slightly different ranking results of the affecting factors, but with the same overall trend. Therefore, the main factors affecting the fracturing effect can be identified in this way.

Key words: hydraulic fracturing, fracturing effect, Xihu oil and gas field, gray correlation analysis, fuzzy curve analysis, affecting factors
