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。借鉴石油工业中的复合射孔技术,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。
Compound technique of perforating can effectively control the perforating direction and the fracturing expansion. The feasibility of this technique used in rupturing coal seams is analyzed. The experiments of perforating and fracturing are carried out on coal samples and the experimental effects are satisfactory. Compound technique of perforating and fracturing is promising in coal seams.
