超深井射孔作业时,射孔弹爆炸瞬间产生的巨大冲击波,将引发管柱的剧烈振动,甚至导致管柱损坏。针对上述问题,运用Hamilton原理,考虑管柱-套管壁接触及超深井高温高压环境等因素的影响,得到管柱系统纵-横-扭耦合非线性动力学模型,并将爆轰压力场与动力学模型相结合,能够准确预测爆轰状态下射孔管柱的振动情况。将研究成果应用于超深井高温高压环境下爆轰射孔对管柱纵-横-扭耦合振动的特性研究,结果表明:合理布置减振器(封隔器以下20~25 m)能有效降低管柱受力,抑制管柱振动,防止管柱与套管发生不良碰撞和减振器的损坏。当单减振器满足不了射孔工况时,双减振器布置能够有效抑制管柱振动,减小管柱受力,增大管串工具的使用寿命。研究成果对降低射孔管柱的安全风险有重大意义。
During the perforation operations in ultra-deep wells,the huge shock wave generated by the detonation of perforating charges can cause severe vibration of the pipe string,potentially leading to string damage.To address this issue,Hamilton's principle is used to develop a longitudinal-transversal-torsional coupling nonlinear dynamic model of the pipe string system,considering the influence of factors such as string-casing wall contact and high temperature and high pressure environment in ultra-deep wells.By integrating the detonation pressure field with the dynamic model,accurate predictions of string vibration under detonation state can be obtained.The research findings are used to study how explosive perforation affects the longitudinal-transversal-torsional coupling vibrations of the pipe string in ultra-deep wells under high temperature and high pressure conditions.The results show that appropriate arrangement of dampers below the packer (20~25 m) can effectively reduce the load on pipe string,suppress the vibration of the string,and prevent adverse collisions between the pipe string and casing and thus protect the dampers from damaging.When a single damper is insufficient for perforation conditions,a dual-damper arrangement can effectively suppress pipe string vibration,reduce the load to pipe string,and extend the service life of the pipe string tools.These findings are of significant importance for reducing the risks of perforation strings.
