摘 要: | 液压锥形防喷器胶心抱紧力的大小是衡量胶心能否可靠封井的重要参数,它决定防喷器的封井性能。通过建立力学模型,时有关载荷进行处理,得到胶心抱紧力与锥形半角θ的函数关系式,计算确定的值,可作为判断防喷器安全封井的依据。

Calculation of the gripping force of the cone packing on hydraulic blowout preventers. |

Abstract: | The well control ability of a hydraulic blowout preventer depends on the gripping force of the cone packing unit. By establishing a mechanical model and dealing with the relevant loads, the authors work out the functional relation between the gripping force q and the cone semiangle θ. The calculated value of q can be regarded as a criterion of the operational reliability of the blowout preventer. |
