API 7-1 IB String Stabilizer with Non-magnetic Body
Product Description
The stabilizer with back reaming is selecting the appropriate location and through special processing method to array few teeth as a cutting edge. In this way, this stabilizer can be played cutting when the process of drilling and pull out. During drilling process, forward and backward redressing can be played the role to repair and maintain the wall of well, making trajectory of borehole as far as possible, more often than not leading to drilling difficulty because of hole shrinkage, and so on, at the moment, the forward and backward redressing of this stabilizer can be played cutting, to eliminate hole shrinkage phenomenon, thus saving time and costs for drilling.
Features
(1). Sizes and configurations can be manufactured to operators requirements, including blade sizes, connections, and types of material.
(2). All stabilizers connections can be configured as box Ã? box, as pin Ã? box, or as the operator requires.
(3). Welded straight blade for drilling soft formations.
(4). Sleeve type allowing less equipment inventory in remote locations.
(5). Integral spiral blade allowing 3600 hole contact for use in hard rock formations.
(6). Nonmagnetic stabilizers for applications requiring magnetic isolation.
