Definitions

  • the present invention relates to a Stabilizer with Front Reamer to be used to stabilize a drilling String during operation.
  • the Stabilizer with Front Reamer of the present invention is directed to an arrangement that will stabilize the drilling string and at the same time to gauge the drilled hole to size.
  • the flexibility of this invention allows for increasing or decreasing the front hole gauging capacity according to need.
  • Stabilizer with front reaming is to provide two main functions:
  • the first function provided by the described device is to act as a reamer.
  • Reamer part is to cut formations to enlarge the bore hole to the desired size, which may be the original size of the bit in the case the drill bit wears to be under-gauged.
  • reamers are employed to cut formations because the bit does not always drill a true circular bore hole and because of slight lateral shifting inherent in the drilling operation; that shifting leaves ledges and other distortions along the bore.
  • Another need for a reamer is due to the interaction of drilling mud with the earth formation; which leads to formation swelling and hence diameter reduction.
  • the second function of this device is to keep the drill stem in the centre of the hole, which means the device acts as a stabilizer.
  • Stabilizers are positioned above the drill bit to ensure that the drill bit - stabilizer assembly drill a straight hole of the desired diameter. Maintaining the drill stem centered has many benefits. The primary benefit is to minimize unintentional hole-angle directional drilling.
  • a stabilizer thereby extends the life of the drill bit by confining the drill string movement into the original hole size.
  • the present invention provides the public with an alternative to existing reamers.
  • a reamer for use in association with a stabilizing element to the drill stem and a drill bit in drilling a hole in a rock formation said stabilizer with front reaming (1) having:-
  • the reamer By arranging hard reaming carbide inserts (8) along the length of the conical body, the reamer is thus is use, brought to bear against the drilled hole-wall at circumferentially spaced positions. The surface of the reamer rubs against the hole-wall thereby ensuring to ream hole back to gauge.
  • said wear surfaces are all studded with a plurality of hardwearing studs, for example carbide surface studs.
  • the stabilizer with front reaming of the present invention may be embodied as either a near bit stabilizer reamer in which the reamer part is adjacent the drill bit in use, or alternatively as a string Stabilizer reamer in which the reaming part is spaced along the drilling string from the drill bit.
  • said spaced apart, axially extending spiral flutes cut into said outer surface are cut at a low angle relative to thereby minimize the extent of helical movement in fluid moving along the flutes.
  • the spaced apart axially and spirally extending spiral flutes cut into said outer surface are milled out, and the distance between adjacent axially spaced wear surfaces are arranged such that, around the circumference of the reamer, a wear surface engages the surrounding hole wall at some point.
