【摘要】 极正压射孔完井新技术特别适用于低渗、非均质严重或污染严重的油气层 ,有利于提高一次完井有效率。本文从极正压射孔完井技术的技术背景分析出发 ,阐述了极正压射孔工艺的类型和基本过程。在对极正压射孔设计理论模型分析的基础上 ,提出了EOP工艺设计基本原则。在中原油田的现场应用表明该工艺对提高油井产能是十分有效的 ,具有较好实际应用和推广价值更多还原

【Abstract】 The New Completion Technique of Exetreme Overbalanced Perforating is Very Effective in Improving Oil Productivity for Wells in Low Permeable or Hihgly Heterogeneous or Badly Damaged Formations. The Types and Procedures of Exetreme Overbalanced Perforating Operations Have been Stated Based on the Investigation of Technical Background. The Theory of Modelling and Designing of EOP Operations Has been Carried Out, Accordingly, its Basic Idea of EOP Job Design Has also Been Brought Forword. Field Test in Zhongyuan Reached a Good Result and Shows Great Practical Importance.更多还原
