发明名称 Oil well blowout containment system
摘要 An oil well blowout containment system which surrounds the polished rod is provided that will capture the oil leaking and blowing past the stuffing box packing gland. In addition, a vessel which is part of the oil well blowout containment system and is located above and sealingly attached to the stuffing box is filled approximately two-thirds of its capacity with a lubricating fluid. The vessel's contents which are in fluid communication with the stuffing box packing gland provide lubrication to the stuffing box packing gland which will deter the wear and hence reduce the replacement of the stuffing box packing gland. A pressure gauge and/or a sight glass provides an indication to an inspector that the stuffing box packing gland has failed whereby the well pump may be shut down and the stuffing box packing gland replaced.
