| 中文摘要: |
| 对复杂地层物探爆破孔钻进存在的问题进行了分析，提出了有效的解决方法，详细论述了贯通式潜孔锤全孔反循环连续取芯钻进技术应用于复杂地层物探爆破孔的原理，特点及可行性，并结合实际试验进行论述，该工艺方法可实现不提钻下炸药柱，解决目前施工中存在的技术难题，具有广阔的应用前景。 |
| 英文摘要: |
| Problems of geophysical prospecting hole in comPlex stratum were analyzed, and effective methods were presented. The paper expoundedthe principle, characteristic, and feasibility of whole hole reverse circulation drilling techno1ogy applying in exploration holes in complex stratum regions,and discussed with practical tests. The technology can bring about putting in explosive package without raising drilling tool. Those will resolve the techni-cal problem at present, and has wide prospect in practice. |
