摘　　要：随着钻井、修井工艺对防喷器组总体高度、体积大小的要求越来越苛刻,为了更好地满足特殊钻井的需求,研制了F18-21整体式防喷器组。通过有限元分析,一次铸钢成型的防喷器壳体满足《井口装置和采油树设备规范》;通过各项性能试验,其壳体强度、液控油缸强度、环形胶芯密封性能、闸板胶芯密封性能、主通径都可以满足现场应用的需要。现场装配结果表明,该整体式防喷器组较常规防喷器组总体高度降低500 mm、总重量减轻600 kg、密封泄漏点减少2处,具有结构紧凑、性能可靠、省时省力的特点。In order to meet the increasingly demanding requirements for the total height and volume of blowout preventer （BOP）stack from drilling and workover technologies, particularly the special drilling requirement, the F18-21 integral BOP stack has beendeveloped. Finite element analysis shows that the BOP shell of one-step cast meets the Equipment Specifications for Wellhead Apparatusand Christmas Tree. Various functional tests show that its shell strength, hydraulic-controlled cylinder strength, sealing property ofannular rubber core, sealing property of valve plate rubber core and main path diameter all meet field application requirements. The fieldassemblage result shows that, compared with the conventional BOP stack, this integral BOP stack is about 500 mm shorter at height,600 kg light at weight, and 2 places less in sealing leaking points. It is characterized by compact configuration, reliable functions andtime-saving and power-saving.
