Top Drive Cementing Head With Single Plug

This is a Single Plug Top Drive Cementing Head. Oilmec top-drive cementing head allows release of setting balls and drillpipe darts without breaking the connection in the running string. The TDH is pre-loaded with the setting ball, drillpipe dart(s), or full-length wiper plugs and can be racked in the derrick for easy access. The well can be circulated through the TDH via a top drive or cement unit with the ball and dart(s) loaded. When circulating through the side bore and/or bypassing dart(s), the maximum pump rate is 15 bbl/min. When pumping through the main bore, after plugs have been released and bypass valves are closed, the maximum allowable rate is 30 bbl/min. The ball and dart(s) can be released by the clearly identified wheels on the TDH.

Features, Advantages and Benefit:

• High tensile, torque, and pressure ratings enable the TDH to withstand conditions that other heads cannot.
• The TDH allows circulation through the top drive and/or cement line, even when fully loaded, simplifying operations and saving rig time while the head is being used.
• The integral swivel facilitates rotation of the drillstring during cementing operations, resulting in a better cement bond

Applications:

• Running any liner, with or without topdrive
• Launching darts and balls related to Sub-Surface Release cementing plug
