ABSTRACT:
A system for sealing around a wireline run into or pulled from wells includes a grease control head with a line wiper mounted on the well head and a grease injection control system. The grease injection control system supplies grease continuously at a constant pressure for injection into the grease control head. The control system utilizes a piston pump to supply grease to a grease chamber in a pressurizing accumulator. The accumulator has another chamber connected to a remote pressure source, which is separated from the grease chamber by a moveable partition. Constant pressure from the remote source is transmitted through the moveable partition to grease in the grease chamber maintaining a constant pressure on grease injected into the grease control head. The sealing system is provided with a conduit to return injected grease pumped through the grease head to a waste grease reservoir for disposal. This conduit includes a valve which may be closed to aid in reestablishing a blownout grease seal.
