摘　　要：低孔低渗透储层产能及产出率低、开发成本高,影响了整个油气产量的增加。为最大限度地提高及恢复低孔低渗储层的生产能力,提高射孔完井的效率,采用了地层二次爆炸射孔技术。介绍了二次爆炸射孔技术主要部件的研制,阐述了相关技术方案及研究成果,并经过现场试验验证了该项技术的可行性。With an increasing proportion of the low porosity and low permeability reservoir of domestic and foreign reserves accounting for proven reserves,problems of the low reservoir capacity and productivity,higher development costs are increasingly prominent affecting increase of. the entire oil and gas production. To maximize increase and restore this kind of reservoir production capacity,improve the efficiency of perforation completion,the secondary explosions perforation technique of formation is utilized. The development of the main components for the secondary explosion perforating technique is described,the relevant technical programs and research are illustrated,and through field tests,the feasibility of the process is verified.
