深水钻井套管柱与海底浅部软土耦合作用研究现状
|
摘要
深水钻井作业过程中,钻井平台、隔水管、水下防喷器组和套管柱是一个整体,钻井隔水管在海洋环境载荷的作用下产生复杂的非线性运动,其底部动态作用力传递到处于海底浅部软土中的套管柱上,使套管柱与其周围的软土之间产生动力相互作用。在该作用力较大时将导致水下井口或套管柱失稳,严重时将使隔水管断裂,致使钻井作业中断,带来巨大的经济损失。因此对目前深水钻井水下井口及套管柱的稳定性分析、套管柱与其周围浅部软土间耦合作用等方面的研究现状进行了综述。
The drilling platform,riser,BOP stacks and the underwater casing string are connected as a unit when deepwater drilling operating.The load of the marine environment acting on the drilling causes the dynamic interaction between the casing string and the seabed soft soil.Then the seabed soil plays a supportive role to the casing strings,and the stability of subsea wellhead or casing string becomes increasingly concerned.It will result in a lot of loss sometimes,therefore,the research on the wellhead mechanical stability for deepwater drilling and the interactions between the casing string and seabed soft soil are reviewed.
