PURPOSE: To remove chips with a dry method by providing two air compressors and a dust collector to a shaft drilling device constituted of a bottom drill assembly body consisting of a cutterhead and weights in a detachable manner, a swivel joint and a stabilizer. CONSTITUTION: A drilling device 10 is constituted of a bottom drill assembly body 28, a swivel joint 26, a drill string 20 and a stabilizer 34. The bottom drill assembly body 28 is constituted of a cutterhead 12, a plenum 14 and a plurality of weights 16 in a detachable manner. A first compressor 36 is provided to the drilling device, compressed air thereof pushes down the cutterhead 12 through the drill string 20, and a riser pipe 18 is made in a state of vacuum by a second compressor through a dust collector 40 to absorb cuttings. By the constitution, the cuttings are stirred with an air nozzle 42, and the cuttings can be removed to the dust collector 40 in a state of vacuum from an inlet 52 through the riser pipe 18 and an outside bore 58.

44 Non-magnetic steel for drill collar having superior corrosion resistance and high strength JP25190884 1984-11-30 JPS61130464A 1986-06-18 NAKAZAWA TAKANORI; SUZUKI TORU; SAKAMOTO TORU; YAMAUCHI ISAMU
PURPOSE: To improve stress corrosion cracking resistance, by incorporating prescribed percentage of Si, Mn, Ni, Cr, Al, Ti, and Ca and by limiting the amounts of C and N to the prescribed percentage or less. CONSTITUTION: The titled non-magnetic steel consists of, by weight, ≤2% Si, ≤2% Mn, 25W40% Ni, 18W30% Cr, 0.1W1.5% Al, 1.5W3% Ti, 0.0005W0.02% Ca, ≤0.015% C, ≤0.01% N, and the balance Fe. This steel excels in corrosion resistance, especially in stress corrosion cracking resistance and, moreover, the homogeneity of material can be secured. COPYRIGHT: (C)1986,JPO&Japio

56 CENTRALIZER FOR DOWNHOLE PROBES EP13853488.8 2013-11-06 EP2917454B1 2018-08-29 LOGAN, Aaron W.; LOGAN, Justin C.; DERKACZ, Patrick R.
A downhole probe is adapted to be supported in drill string sections having different internal diameters with the use of a set of interchangeable centralizers. Each centralizer is dimensioned to snugly receive the downhole probe and to bear against the bore wall of a drill-string section. Interchangeable axial supports such as spiders may also be provided in a set. The downhole probe may comprise a slick body. As drilling progresses the downhole probe may be adapted to be received in drill string sections of varying diameters.

A rock drilling shank adaptor having at least one flush hole extending radially through the body of the adaptor in communication with an axially extending internal bore. The flush hole in a direction from an external side to an internal side comprises a surface at a rearward region that is curved at least at a radially inner portion to extend in an axial direction towards a forwardmost end of the adaptor to increase the resistance of the adaptor to stress concentrations whilst achieving a desired flow rate of flushing fluid flow into the internal bore.

59 FRICTION REDUCING WEAR BAND AND METHOD OF COUPLING A WEAR BAND TO A TUBULAR EP10714737.3 2010-04-07 EP2417324B1 2017-05-17 BUYTAERT, Jean; MILLER, Eugene, Edward; HINING, Ira, Eugene
In one embodiment, a wear band comprises a rotating element having a bore receivable on a tubular, the bore comprising first and second bore portions slidably receiving first and second sleeve bearings. Outer surfaces of the sleeve bearings slidably engage the bore portions and the bores of the sleeve bearings slidably engage the tubular. A first stop collar and a second stop collar may be received on the tubular to together straddle the rotating element and sleeve bearings to longitudinally secure the rotating element in a position on the tubular. The tubular may be included within a tubular string run into a borehole or into the bore of an installed casing, such as in casing while drilling. The rotating element provides stand-off between a tubular and the wall of a bore, reduces frictional resistance to longitudinal sliding and also to rotation of the tubular string within the bore.
60 IMPROVEMENTS IN OR RELATING TO DATA COMMUNICATION IN WELLBORES EP15713549.2 2015-03-13 EP3155219A1 2017-04-19 MAYLIN, Mark Gregory; BOWLES, Adrian Robert; JONES, Micheal Alan
Method and apparatus to allow continuous recovery and broadcast of data and commands to and from a tubular string (32) through all phases of drilling and completion running in a wellbore. A RF transceiver (76/74) is located on the tubular string, the transceiver being adapted to receive signals and broadcast the signals, and a RF transceiver (88/90) is located remote from the tubular string and adapted to receive the broadcasted signal by virtue of an antenna (92) arranged within a fluid filled annulus (60) around the tubular string. RF transmission through the wellbore using distributed RF transceivers providing data and command transmission up and down the tubing string.
