水力压裂技术在无保护层低渗透率单一煤层增透中的应用

摘要

Hydraulic Fracturing is one of the Most Effective Way to increase the Permeability of Coal Seam. In This Paper, Application This Method Make a Test in the Unprotected and Low permeability Single Coal Seam, Prove that can Effectively increase the Permeability and im-prove the Single Span Gas concentration and Gas Drainage, for the Same Type of Anti-reflection has Certain Reference Significance.%水力压裂是目前最有效的增加煤层透气性的方法之一。本文应用该法在无保护层的透气性较差的单一煤层中进行了穿层钻孔压裂试验，证明可有效增加煤层透气性，提高单孔瓦斯浓度和瓦斯抽采量，对于同类型的的矿井煤层增透具有一定的借鉴意义。
