针对化石能源开发中储层改造技术的局限性,创新性地提出了重复脉冲强冲击波增透储层新技术。分析了水中放电、金属丝电爆炸和电爆炸等离子体驱动含能混合物产生冲击波的3种机理。介绍了冲击波作用储层的机理研究和现场应用结果,从理论、实验和现场实践验证了冲击波技术增透储层的可行性。结果表明,以电爆炸等离子体驱动含能混合物产生更强的和区域可控的冲击波,可针对储层做单点多次、分段式的增透改造,在化石能源开发中的意义重大。

We evaluated the limitations of reservoir reform technology in fossil energy development, and proposed a novel reservoir stimulation technology based on repetitive strong shock waves caused by pulsed discharge.Meanwhile, we analyzed the principles of the three kinds of shock wave generation technologies, i.e., underwear pulsed discharge, underwater electrical wire explosion, and plasma-ignited energetic materials.Moreover, we discussed the influential mechanisms of the shock waves on reservoir and results of recent industrial applications, and proved the technical feasibility by theoretical calculations, laboratory experiments, and several related practices. It is concluded that plasma-ignited energetic materials may be utilized to produce stronger and controllable shock waves, helping to enhance the effects of reservoir stimulation.
