目前河南油田射孔完井方式约占油气生产井和注入井的90%以上,射孔枪弹的选择、射孔伤害机理、射孔参数的优化设计与应用不但直接影响油井的产能,也对套管强度、注汽效果有着较大影响,射孔枪、弹和工艺的选择直接关系到射孔成本费用高低,优选设计射孔参数应以降低其经济预算为前提,以加强设计针对性为基础,鉴于此,本文针对河南油田部分区块的射孔枪弹、射孔工艺、射孔参数进行评价优选,仅供参考。
At present, the perforation completion method of Henan Oilfield accounts for more than 90% of oil and gas production wells and injection wells. The selection of perforation bullets, the mechanism of perforation damage, the optimization design and application of perforation parameters not only directly affect the productivity of wells, Pipe strength and steam injection effect have a greater impact on the choice of perforation guns, bombs and processes directly related to the cost of perforation costs, the optimal design of perforation parameters should be to reduce its economic budget as a prerequisite to enhance the relevance of design-based In view of this, this article aims to evaluate and optimize perforation bullets, perforation technology and perforation parameters of some blocks in Henan Oilfield for reference purposes only.
