BYJ-100 snub rigs, with full hydraulic driving system and electric / hydraulic control, are powered by diesel engine. During operation, firstly, to close the traveling slips and upper BOP, and clamp tubings; Then to open the fixed slips and lower BOP, and raise the traveling system ( traveling slips, upper BOP and well fluid sealing cylinder ) by one tubing distance using main cylinder; Then to open traveling slips and upper BOP, and the traveling system will drop, then remove one tubing which will be sent to ground through balance winch. Repeat the above procedure until completion of pullout of tubing and downhole tools ,and then close full-seal BOP. This process eliminates dynamic friction between BOP and tubings which happen in old way, thus service life of sealing parts will be greatly lengthened, and operation cost is reduced.
◆ New equipment, new process, environmental protection, high effciency.
◆ Fully hydraulic system, convenient and easy operation. Max. lifting capacity:220462 lb ( 100t ) ,suitable
◆ For operations in most medium & shallow wells.
◆ Dynamic sealing problem of tubing under pressure is completely resolved.
