中文摘要:
      目的 探究顶端平台激励和泄流效应对深海钻井立管紧急脱离反冲动态响应的耦合作用。方法 采用集中质量法,据外力矩阵和内流液柱加速度计算方法的不同来构造钻井立管紧急脱离反冲响应四种分析模型,利用Newmark-β方法探究大长径比深海钻井立管在紧急脱离时,顶端浮式平台和管内泄流柱(钻井液泄流和海水注入过程)对立管反冲响应的耦合效应。结果 顶端平台激励和泄流效应对钻井立管紧急脱离反冲过程,尤其是断开初始阶段立管低端总成和油井口的距离有重要影响。结论 在深海立管紧急脱离动态特性分析以及优化设计控制系统时,必须考虑顶端平台和管内泄流柱对反冲立管的共同耦合作用。
英文摘要:
      Objective To explore the coupling effect of top platform incentive and discharge flow effect on dynamic recoil response of deepwater drilling riser after emergency disconnection. Methods The coupling effects of the top platform and the discharging flow column (in the mud discharge and seawater refilling process) on the recoil response of a drilling riser after an emergency disconnection were researched with four different mathematical model based on lumped mass method and different formulas for the external force matrix and the internal flow column acceleration, which can be solved by use of Newmark-β method. Results Thetop platform excitation and the discharging flow effect could significantly affect the recoil after emergency disconnection, especially the distance between the lower end assembly of the raise and the well head in the initial stage. Conclusion The combined coupling effect of the top platform and the discharging flow raise should be taken into consideration in dynamic recoil analysis and control system design for emergency recoil of deepwater drilling riser.
