| 摘 要： | 深水海底常常潜伏着大量的高压浅层气,而深水钻井过程中钻遇浅层气是十分危险的。结合动力压井方法对如何处理浅层气问题进行了研究。首先根据海上钻井工艺的技术特点,结合动力压井工艺进行了探讨,得到了深水钻井过程中处理浅层气的工艺技术。然后以此为基础,考虑有隔水管情况下井筒内的多相流动情况,建立了动力压井参数计算多相流方程,并进行了求解。计算结果表明,动力压井初期阶段,伴随着浅层气体积膨胀,动力压井排量会有所增加,当浅层气逐渐排出井筒后,钻井液排量会有所下降,直至达到稳定值。在实际的动力压井过程中,为了保证井壁的稳定性,应适时对压井排量进行调整。

| Abstract: | There are so many shallow gas pockets with abnormal pressure underneath deep seabed,and it is dangerous to meet shallow gas during deep water drilling.In order to solve the safety problems caused by shallow gas,the dynamic kill technology was investigated.First,based on the characteristics of deep water drilling technology,the dynamic well kill was investigated,and the well kill technique for shallow gas in deep water was obtained.Second,considering multiphase flow in the well and marine riser,a multi-phase... |
