摘要:
救援井压井多相流动水力参数设计是深水井喷防控的关键。基于连通点处压井液下落判据,考虑连通点以下零表观液速流流型转化条件,建立了深水救援井压井多相流动理论模型。模型计算结果表明:本文所建模型与Drillbench商业软件计算结果和实验数据趋势一致,具有较高精度; 大排量、高密度压井液容易快速实现压井; 宾汉流体较牛顿流体更易实现压井,随着流体屈服值增大,压井时间缩短。本文研究成果对于深水救援井动态压井设计具有一定的指导意义
Abstract:
The stability of subsea wellhead is a key factor affecting the shallow strata drilling safety of deep water regions. In this paper, the research progresses on wellhead stability of deep water drilling at home and abroad in recent years are reviewed. The effects of some parameters on the vertical and lateral stability of wellhead are discussed, including the conductor parameters, soil properties, engineering parameters and environmental load. Additionally, special wellhead devices are designed to mitigate or avoid the hazards of wellhead instability such as surface blowout preventer system, suction pile wellhead foundation, combined pipe foundation, and pipe bearing capacity strengthening device are introduced and evaluated. The research results in this paper can serve as a reference for the study of subsea wellhead stability in deep water drilling in China
