超稠油由于存在“四高一低”的特点,在开采过程中由于超稠油特殊的开采方式,造成油井下泵初期温度高、含水高;中后期粘度高、温度低;末期液量低、间出等问题,导致了“盘根需要频繁换,井口需要频繁擦”的恶性循环。为了解决井口跑油的问题,研制了超稠油井循环润滑光杆密封器。 Due to the existence of “high and low” super-heavy oil in the mining process due to special super-heavy oil mining methods, resulting in the initial underground oil well pump high temperature, high water; high viscosity in the late post-low temperature; Low volume, between the other issues, resulting in “packing needs frequent change, wellhead needs frequent wipe ” vicious cycle. In order to solve the problem of running oil in the well head, a super-heavy oil well circulating lubrication rod seal was developed.
