摘要
通过对比各种结构不压井作业装置,确定了独立式不压井作业装置为橇装式短冲程全液压结构形式。采用模块化设计,设计了性能优良的环形胶芯和闸板胶芯;采用锥形自紧式卡瓦实现对管柱的有效控制。介绍了桅杆绞车系统和液压控制系统。现场试验结果表明:该独立式不压井作业装置运输和安装方便、快速,卡瓦和液控系统安全可靠,防喷器密封性能良好,作业效率高。
In contrast with different snubbing units,the unit configuration uses skid-mounted,short stroke and full hydraulic.The blocking design,comprising driving blocking and well operation are introduced.Performances of annular and ram packers are excellent.The taper slip with self tightening function is applied for controling pipe effectively.The backstay winch system and hydraulic control system are introduced.Experimental results in field indicate the stand-alone snubbing unit is transported and fitted conveniently,slip and hydraulic control system are safe and credible,the BOP has better sealing performance and higher efficiency.
