EZY-CHANGE TYPE II RIG-REPLACEABLE SLEEVE-TYPE STABILIZER

A cost-effective deviation control product

The Integral blade Stabilizer (IBS)
is manufactured from high-strength alloy steel as a single piece tool. The unitized construction features three spiraled ribs designed to minimize down hole torque, reduce damage to the hole wall and ensure maximum fluid circulation. The IBS is well suited for use in most formations from soft and sticky to hard and abrasive. It is available in both bottom-hole and string designs, providing the flexibility to run it anywhere in the BHA.

When the blades wear down to an unacceptable diameter, the tool should be removed from the drilling assembly and returned for servicing – OTI where it can usually be redressed to full gauge size.

 FEATURES AND BENEFITS:

  • The blades are an integral part of the tool body, eliminating the risk of leaving components or pieces in the hole.
  • Available in both “open” and “full wrap” designs, providing optimum hole wall contact while ensuring maximum fluid bypass area.
  • Available in Type 200 and Type 300 wear surfaces.

 

APPLICATIONS:

  • A packed hole assembly typically requires the placement of multiple IB stabilizers throughout the three zones of stabilization. Contact an ACE-O.C.T.G. representative for BHA recommendations.
  • A pendulum assembly is a recommended application for the IBS due to its unitized design. For the most effective pendulum assembly, two stabilizers should be run separated by one drill collar.
  • Vibration and drill collar whip can be reduced through the placement of stabilizers in the BHA and upper drill collar string.

Notes:

  • All dimensions are given in inches unless otherwise specified.
  • All weights are approximate.
  • Nominal rib diameter will be as follows:

4¾" through 12¼" hole sizes are nominal +0, -1∕32"; 13 ¾" through 17½" hole sizes are nominal +0, -1∕16"; 18" through 28" hole sizes are nominal +0, -â…›". Non-standard tolerances are available on request.

The stabilization system designed for remote or space limited locations

This tool is designed around a rugged, one piece mandrel constructed of high-strength alloy steel with ample tong space for handling and extra length for recutting connections. The rig-replaceable, integral blade sleeves are available in three types (listed below).

 The Ezy-Change Type II is a popular choice for remote areas or where storage problems exist. One mandrel series can be used for several different hole sizes, reducing the need for a large mandrel inventory on location. The sleeves are easily changed on the rig floor either when changing hole size or when the sleeves have worn under gauge. This versatility also allows a convenient way to change the type of stabilizer wear surface to match drilling conditions. A simple plate plate-type sleeve breaker (available on request) enables easy make-up and breakout.

The Ezy-Change Type II is available in five tool series covering hole sizes from 8½" and 28" and can be ordered as a string or bottom-hole tool.

FEATURES AND BENEFITS

  The 17½” and smaller   Sleeves feature three spiral blades; larger sizes have four straight   blades.

  •  Annular flow area is   Maximized to ensure adequate circulation.
  •  Hardfacing choices include Type 300, Type W granular Tungsten carbide and Type 200.
  •  One-piece mandrel Design is simple and Strong. 
  •  Long fishing and bottom   neck provide plenty of tong space and room for recuts.
