摘　　要：钻井起钻卸单根过程中,钻井液从钻柱接头处喷溅而出,不仅威胁工作人员健康安全,而且污染平台设备,为此研制了可变径钻杆防喷盒。该防喷盒为圆筒开合式结构,通过控制钻柱接头钻井液喷溅压力来回收和循环钻井液。运用Solidworks绘制防喷盒模型,采用ANSYS对其MC尼龙材料进行分析。在江汉油田焦页4-2HF井和31-1HF井的试验中,可变径钻杆防喷盒具备良好的承压能力,试验效果良好,共收集钻井液36.24 m^3,比常规起钻至少节约3 h。设计的可变径钻杆防喷盒实用性强,符合现场以及HSE要求。The overflows of drilling fluid from drill pipe joint during break out after tripping out not only create risks for the health and safety of staff, but also pollute the platform equipment, thus, the variable?diameter drill pipe mud saver has been developed?The mud saver adopts the cylinder well?formed structure, recycling and circu?lating the drilling fluids by controlling the spray pressure of mud at drill string joint?The model of mud saver is de?signed using software of Solidworks, and the applied MC nylon material is analyzed using ANSYS?Field applica?tions in Well Jiaoye 4-2HF and Jiaoye 31-1HF in Sinopec Jianghan Oilfield show that the mud saver has good pressure?bearing capacity, and it had collected 36?24 m3 mud in total and saved more than 3 hours in pulling out process?The mud saver has great practicability and could meet the required standards of the field application and HSE rules.
