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.
