摘要
三级井控情况下,为控制高速喷出的井口流体,需在井口安装防喷器,建立压井通道,重新恢复对井的控制。通过法兰或者卡瓦机构在套管上“生根”,依靠吊装、扣装和磨装三种方式,完成防喷器的安装,对陆地和海洋井喷抢险均有借鉴意义。
In the case of tertiary well control,blowout preventer should be installed at the wellhead to establish the kill channel and restore the control of the well in order to control the high-speed ejected downhole fluid.By"rooting"on the casing through flange or slip mechanism,blowout preventer can be installed from axial or circumferential direction,which can be used for reference in both onshore and of fshore blowout.
