复合水动力射孔技术是用非爆炸的方式打开油气层的一种新的射孔方法。射孔器一次下井,可同时完成射孔、冲洗、抽汲和注酸多项作业。运用该技术能够更深穿透近井压实带,增大压实带的渗透率,并且对套管和水泥环损害更小,是一种高性价比的完井及油层改造措施。介绍了俄罗斯NEKKO公司的复合水动力射孔技术的工作原理、技术特点、适用范围和应用情况,通过射后效果与聚能射孔的对比分析,证明该射孔工艺具有较强的技术优势和较好的推广价值。
Composite hydrodynamic perforation technology is a new perforation method that opens a hydrocarbon reservoir in a non-explosive manner. Perforating wells once, can complete perforation, flushing, pumping and acid injection a number of homework. Using this technique, it can penetrate the near-well compaction zone deeper, increase the permeability of the compaction zone, and cause less damage to the casing and cement sheath. This is a cost-effective completion and reservoir modification. The working principle, technical characteristics, applicable scope and application of compound hydrodynamic perforation technology of Russia NEKKO Company are introduced. By comparison of the post-injection effect with the perforation, it is proved that the perforation technology has strong technical advantages and Better promotion value.
