| 摘 要： | 为了解决长庆油田采油四厂注水井两段或三段注水时吸水不均问题,该厂曾分别用无壳弹和多级脉冲射孔压裂复合技术进行了尝试,结果表明多级脉冲射孔压裂复合技术具有良好的地质效果.从两种火药结构的燃烧性能和作用机理解释了该技术的作用机理.得到了两种火药结构在实验室和井下的压力—时间曲线,通过对曲线分析得到了多级脉冲射孔压裂复合技术能改变注水井上段不吸水的原因.

| Abstract: | No. 4 Production Plant of Changqing Oilfield Company tested case-less ammunition technology and multi-stage pulse perforation-fracturing technology separately to solve the problem of the water-absorbing non-uniformity in the process of two-section or three-section water-injection. And the results show that the multi-stage pulse perforation-fracturing technology has better result. The mechanisms of the two technologies are discussed from the combustion performances and the effecting mechanisms of the two ammunition structures. The pressure-time curves of the two ammunition structures are gained in laboratory and in field separately. The reasons are analyzed according to the obtained curves why the multi-stage pulse perforation-fracturing technology can improve no water absorbing of the upper section of water injection layer. |
