摘要
复合射孔技术能有效地控制射孔方向和压裂缝的扩展。对其应用于煤层致裂进行了初步的实验研究。针对煤层的特性 ,介绍了煤质模型的射孔与高能气体压裂 (HEGF)实验的研究情况 ,结果表明 ,射孔和压裂效果良好。复合射孔技术必将成为煤层致裂发展方向之一。
Compound technique of perforating can df fectiv ely control the perforating eirection and the fracturing expansion.The feasibili ty of this technique used in fracturing in coal is analyzed.The expe riments of perforating and fracturing are carried out on samples of coal and the experimental effects are satisfactory.Compound technique of perforating and fra cturing is promising in coal.
