Research on Calculation of Riser Gas Injection Dual-Gradient Drilling Wellbore Parameters

  • 摘要:

    基于隔水管注气双梯度钻井过程中隔水管环空多相流特性,建立了隔水管注气双梯度钻井环空多相流模型,采用有限差分法对模型进行求解,结合墨西哥湾某口深水井现场数据,分析了钻井参数对井底压力和环空压力的影响,并对注气流量的影响因素进行讨论。研究结果表明:隔水管注气双梯度钻井井底压力比常规钻井更低,更适用于海底窄密度窗口钻井;隔水管注气双梯度钻井在钻井过程中注气流量的大小对井底压力和环空压力影响较大;水深和钻井液密度是影响注气流量的两个重要因素。在隔水管注气双梯度钻井参数设计时,应选择合适的注气流量,且钻井液密度不宜过大,以确保隔水管注气双梯度钻井安全。该研究对隔水管注气双梯度钻井设计及现场作业具有指导意义。
