建南气田志留系储层压裂改造技术研究

建南地区志留系砂岩储层温度具有高温、高压、超深、致密的特点,通过对储层深入认识,分析得出深层致密砂岩压裂改造关键点,结合室内研究和以往志留系储层施工经验总结,最终形成了一整套适应于志留系深层致密砂岩气藏的压裂改造技术,在建志1井现场应用获得成功,为志留系储层的下步压裂开发打下了良好基础,同时对国内同类型的深层致密砂岩压裂改造也具有重要指导意义。

Analysis of Fracturing Technique Applied to Silurian Reservoir in Jiannan Gas Field

Silurian sandstone reservoir features high temperature,high pressure,extra depth and density.By a further analysis of the reservoir,the author has found the key point in fracturing of compact sandstone in deep layer and established a complete set of fracturing technique adapt to Silurian deep compact sandstone reservoir on the basis of laboratory study and summary of past operation experience in Silurian reservoir.The technique has succeeded in practice of Jianzhi Well-1,which has laid a good foundation for next fracturing of Silurian reservoir and has the important sense in fracturing in the same type of deep compact sandstone.
