且能可靠对闭并口，提高了并喷抢险作业的安全性。
并喷抢险装主要由支撑系统、生根系统、起升系统、对中系统、对并系统
和套管卡紧系统组成。作业过程：支撑架将并喷抢险装置支撑在并口，支撑架上的液压缸推动固定架向前运动，者到达指定位置后生根系统卡紧委管本体，实现并喷抢险装置的生根；在对中系娩的作用下，封并系统在水平面内前后左右运动，使封井系统的轴线与套管的轴线共线；升降系娩带动对并系统下降，到达指定住置后封并系统停止运动；关闭环形防喷器和全对阐板防喷器，分别对闭封并系统与套管间的环空空间和套管内孔。对各系统进行了详细的结构设计并且利用ABAQUS有限元软件对关键零部件进行了有限元分析。分析结累表明，装置的强度与明度均满足要求，针对目前钻并并喷事故中抢喷时间长、作业危险性高的现状，并喷抢险装置能够快速与并口光套管连接，及时制止并喷，可封闭压力达35MPa的并口

Abstract: A blowout emergency rescue device was designed to deal with the uncontrolled blowout in the process of drilling opera-tion. In the mode of remote control, this device can be connected with the bare casing and seal the wellhead reliably, so as to improve thc safety of blowout emergency rescue operation. This blowout emergency rescue device is composed of supporting system, root system, so e s ssad oeo ss e se e ss de ass ea ass s blowout emergency rescue device is supported at the wellhead by the supporting frame, and the fixed frame is pushed forward to the assigned position by the hydraulic cylinder on the supporting frame. Later, the body of the casing is clamped by the root system, and thus the blowout emergency rescue device is rooted. Second, by virtue of the centralizing system, the capping system moves horizontally all around to make the axial line of capping system aligned with that of the casing. Third, the capping system stops moving after it is lowered by the hoisting system to the assigned location. Fourth, the annular BOP (blowout preventer) and the blind ram BOP are shut down to seal the hole inside the casing and the annulus space between the capping system and the casing. All systems were structurally designed in detail and then finite element analysis was conducted on the key parts by using ABAQUS finite element software. It is indicated that the strength and stiffness of this device are satisfactory. Faced with the long rescue time and high operation risk of current blowout acci-
