The calculation and experiment results show that the maximum lifting pressure performance decreases with the increase in throat diameter of channel of variable section, water flux of low pressure and pressure ratio of steam nozzle, and has its minimum value with water nozzle annular space. The coefficient of maximum lifting pressure performance may be as high as 26. In the design of steam injector, the larger pressure ratio of steam nozzle and the smaller water nozzle annular space are selected, the higher lifting pressure performance could be obtained.

计算及研究表明：极限升压能力随变截面混合腔喉部直径、被升压的低压水流量和蒸汽喷嘴压比增加而降低，随环形水喷嘴间隙的变化出现了最小值；计算得出变截面超音速汽液两相流装置的极限升压能力可达26；在设计升压装置时应尽可能选取较大的蒸汽喷嘴压比和较小的环形水喷嘴间隙。

The main feature of the annular preventer (Fig. 2), sometimescalled s'universal" or "bag''-type BOP, is the capability to close and seal on almost any size tools in the borehole-drillpipe, tooljoints, drill collars, kellys, easing, etc.-within most of its range, It also has the capability to seal off the open hole, The heart of the annular preventer is the sealing element Fig.
