Oilfield Wellhead Grease Injection Control Head Wireline Operation
The Grease Injection Head is designed to perform a wireline sealing function on braided cable. Positioned at the uppermost point of the pressure control equipment string, the Grease Injection Head comprises two major sub assemblies: the stuffing box or pack-off and the flow tube assembly.
The flow tubes are close tolerance fitting around the wireline. Along with the flow tube sleeves, they form the main length of the grease injection control head. This length provides sufficient column height when in service to form an effective grease seal. In operation, the Grease Injection Head is assembled around the wireline before it is attached to the rope socket. The tool string is connected to the rope socket and lowered into the lubricator, with the well shut in below.
