摘要
气体钻井过程中,常规的配套工具无法满足工艺要求,为此而研制的气体钻井用钻杆阀由钻杆阀短节、缓冲垫、密封部件、阀座、销轴、圆柱扭簧和阀板等组成。该阀不仅具有常规单向阀的功能,还可使测斜仪上下顺利通过,不影响测斜作业。现场试验表明,钻井阀开关灵活,密封可靠,提高了气体钻井时接单根的效率和作业的安全性,测斜时不碰、挂测斜仪。
The developed drill pipe valve used in gas drilling is made up of nipple,cushion,sealing parts,valve seat,pin bearing,cylindrical torsion spring and valve plate.The valve not only possesses the functions of ordinary check valve,but also allows the inclinometer to pass through it smoothly without affecting the deviational survey.The field test indicates that characterized by flexible switching and reliable sealing,the new drilling valve can improve the efficiency of connecting individual pipe while gas drilling and the operating safety without touching or sticking the inclinometer while performing deviational survey.
