General description

The Varco PS15 Power Slip is a manually operated slip for the setting and releasing of drill pipe slips for 3-1/2" to 5-1/2" drill pipe.

The Varco PS16 Power Slip is a fully automatic, remote controlled, air operated system for the setting and releasing of drill pipe slips for 3-1/2" to 5-1/2" drill pipe (Figure 1). The PS16 can accommodate 6-5/8" drill pipe, but only as a tripping tool.

Both the PS15 and the PS16 eliminates the difficult and sometimes dangerous job of hand setting and lifting of drill pipe slips. The PS15 Power Slips can be set by the crew members simply standing on the slip set ring. The PS15 slips use coil springs as a counter balance to offset the weight of the slips when in the upper, or, released position. The PS16 power slips can be controlled by either a hand or foot operated remote control valve. The PS16 slips are set by gravity and released by applied air pressure. The PS15/16 is designed to fit into 27-1/2" and 37-1/2" to 49-1/2" rotary tables equipped with Varco pin drive master bushings. The PS15/16 is a non-rotating unit designed for use with the Varco top drive drilling system.

CAUTION: Do not use 6-5/8" drill pipe with the PS16 to drill ahead.

Figure 3. PS16 Power Slip (top view)

Top cover assembly (PS16 only)

The top cover assembly consists of two identical halves. The flat, top surface is designed to accommodate TDS elevators while drilling to the floor. The rod ends of the two air cylinders connect to the top of the cover assembly with hex-head screws.

At the bottom of the top cover assembly are four clevises for mounting slip assembly hangers and four holes which accommodate the guide pin studs. The studs are attached to the top cover with special torque nuts torqued to 250 ft lb (338 Nm).Air cylinders (PS16 only)

The two air cylinders lift the top cover assembly and attached slip assemblies approximately 8-1/2" on the application of 90 psi air. Lifting the slip assemblies releases the drill string.

Each air cylinder rod has an 8-1/2" stroke. They are tapped in the end to accommodate the 1" hex-head screw used to attach the rod to the top cover assembly.

Each air cylinder has four 1/2" tapped ports top and bottom (2 on each side) to accommodate 1/2" NPT fittings for the control system. The air cylinders attach to the bowl assembly with a special bottom bracket and 1/2" screws.

Bowl assembly

The PS15/16 bowl assembly consists of two halves connected with a bowl hinge pin to enable the installation and removal of the power slips around the drill string.

Inside the bottom of the bowl assembly is a groove to accommodate the mounting of the replaceable guide ring. Four guide pins (2 on each side), that attach to the top

cover assembly provide stability to the system. Each guide pin bushing has a grease fitting for lubrication.

Slip assembly

The slip assembly provides the means for gripping the drill string. Four slip segments are required for each PS15/16. The slip segment consists of a slip body, slip hanger, slip inserts and attaching hardware (Figure 4).The slip is available in three sizes. The 4-1/2" slip is used for drill pipe sizes 3-1/2" to 4-1/2". The 5-1/2" slip is used for drill pipe sizes from 4-1/2" to 5-1/2". The 6-5/8" slip is only used for tripping.

Slip inserts vary for each pipe size and depend on the size of the slip used (see the table in Figure 5).

Guide ring

The guide ring keeps the drill string centered to enable proper operation of the slips. The guide ring also provides channels for the PS16 slip assemblies, keeping them spaced evenly, assuring that the drill pipe is gripped evenly during slip setting. The guide ring is precision machined and consists of two matched halves to accommodate the opening of the bowl assembly.

Because excess guide ring wear is detrimental to PS16 performance, monitor internal guide ring surface wear closely. Replace the guide ring if wear exceeds 3/16" (4.76 mm)

Installation PS15/16

Check that slip and slip inserts match drill pipe size in use.

Check that the installed guide ring is correct for the size of drill pipe in use. Guide rings can be identified by looking at the figure stamped on the end section of the two halves. (Figure 7).

Figure 7. Guide ring identification and measurement

The following installation procedures assume that all pre-installation planning and rig up has been accomplished prior to PS15/16 installation. This includes:A Varco pin drive master bushing is installed in accordance with Varco specifications and any bushing insert has been removed.PS16 only: Rig 100 to 150 psi air has been piped in, flushed clean, and pressure tested. The size of drill pipe to be used in rig operation has been determined.

Procedure

NOTE: The slip size (4-1/2" or 5-1/2") is stamped on the side of the upper slip body. The insert P/N is stamped on back of slip insert. A B stamped on the insert after the P/N indicates a beveled edge insert for use on either the top or bottom of the slip dovetail slot.

NOTE: An undersize guide ring can interfere with the tool joints causing severe equipment failure. An oversize guide ring cannot center pipe and tool joints can catch and accidentally set slips, resulting in severe damage.

Installation PS16 control system

Connect filter/regulator and lubricator assembly to the rig air standpipe. Set the regulator to 90 psi. Locate and mount the inline pilot operated valve and pipe in to the filter/regulator. Note

that the inline valve must be mounted within the 23' reach of the two hoses supplied with the PS16.

Mount the hand operated pilot valve and pipe in 1/4" tubing from the lubricator output to the valve inlet.

Route 1/4" tubing from the hand operated valve to the pilot inlet of the inline valve. Hoist the PS16 onto the rig floor near the rotary table.

Lubricate the power slips per the Lubrication section. Connect the two air hoses provided from the inline valve to the PS16 and check power slip

operation by operating the hand valve several times. Take a strain on the drill string, if any, and remove the slips currently in use. Raise the PS16 off of the rig floor and open the bowl assembly. Guide the power slips around the drill string, if any, and lower into the master bushing

(Figure 8).

Operate the control valve to SET and slowly lower the drill string to set slips.

Procedure

NOTE: The PS16 weighs approximately 1,600 lb (725 kg)

NOTE: To prevent the power slips from pulling out of the master bushing during operation, lock in the power slips with the master bushing pins.

5: Operation

www.nov.com

Operation PS15

1. The slips are set by stepping on the step rail on the outside of the cover

2. The slips are held set by the drill pipe weight and the latch with latch lock serves as a safety if the driller was to pick up the accidentally on the drill pipe, but didnt want the slips to come up.

3. To allow the slips to come up, step on the latch-lock-pedal.

Theory of operation PS16When the hand-operated pilot control valve is operated to the SET position, the 90 psi pilot air stream is removed from the inline valve. This allows the spring-loaded internal valves to direct 90 psi air from the filter/regulator through the low pressure hoses to operate the check valve located on the PS16 (Figure 6).Releasing the check valve exhausts air from the bottom of the air cylinders through the inline valve to the atmosphere.

Taking a strain on the drill string and moving the hand control to the RELEASE position directs a 90 psi air stream to the inline valve operating internal valves, directing air from the filter/regula-tor to the bottom of the air cylinders located on the PS16. This air pressure extends the cylinder rods, raising the top cover and attached slips, releasing the drill pipe.

Procedure

CAUTION: Make sure down far enough to go past the latch cover.

WARNING: Ensure the pipe has stalled prior to setting the slips.

NOTE: Ensure there is sufficient weight before using the PS, e.g. after the bottom hole and heavy weight has been run.

WARNING: Power slips should be left in the locked or SET position while supporting pipe or casing and not released until secondary support of the string is in place. Under certain conditions, e.g., very light loads, releasing the slips before picking up the load can result in a dropped string.

WARNING: Do not use the 6-5/8" power slips as anything other than a tripping tool. Severe damage can result when drilling ahead using 6-5/8" pipe and the PS16.
