摘要:
3 000 m水深水下应急封井装置的下放安装受井喷原油流速的影响较大,为确保3 000 m水深水下应急封井装置顺利下放安装到发生井喷的井口,基于ANSYS软件建立并模拟了3 000 m水深水下应急封井装置下放安装过程,研究了水下应急封井装置在不同井喷原油流速、距离井口不同高度时的平衡状态。研究结果表明,水下应急封井装置距离井口不同高度时,上托力与湿重平衡时对应不同的井喷原油流速; 相同井喷原油流速下,水下应急封井装置从下放到距离井口1 m过程中,距离井口1 m时受到井喷原油产生的上托力最大。本文研究结果对水下应急封井装置快速平稳下放及水下应急封井装置的优化设计具有一定的参考意义
Abstract:
The landing of subsea capping stacks to a depth of 3 000 m is largely affected by the blowout velocity of crude oil. In order to ensure that the 3 000 m deep subsea capping stack can be smoothly landed and installed at the wellhead where blowout occurs, the landing process of subsea capping stacks was established and simulated based on ANSYS software, and the equilibrium state of the stacks at different blowout velocities and with different distances from the wellhead was studied. The research results show that, if the subsea capping stacks are at different distances from the wellhead, the corresponding blowout velocity varies when the uplift force and wet weight are balanced. During the process of landing the subsea capping stack, for the same blowout velocity, the uplift force generated by the blowout crude oil reached the maximum when it was 1 m above the wellhead. The results have certain significance for the smooth installation and the optimization design of subsea capping stacks
