Definitions

  • This invention relates to a tool intended to maintain a drill bit in constant contact with the bottom of a well boreduring.drilling.
  • a valve .means may be incorporated in the present invention so that fluids may be circulated to the well bore at any desired elevation therein above the drill bit and beneath the tool of the present invention to flush debris or sediment from between the drill string and the well bore in which the present invention is employed.
  • suitable jar means and preferably the jar means as disclosed in U.S. Patent 3,233,690 or 3,208,541 may be employed in the drill string to selectively impart either up or down jars or blows to the drill string should such drill string tend to become stuck or become, stuck during drilling operations.
  • the present invention provides a mandrel which extends longitudinally of the drill string adjacent its lower end with a drill bit being secured to the lower projecting end of the mandrel.
  • Spring means are supported by the drill string and abut the mandrel to tend to urge the mandrel longitudinally out of the lower end of the drill string into constant contact with the well bore bottom during rotary drilling operations, and helical groove means extending longitudinally of the mandrel in which are engaged rollers which are supported by the drill string.
  • Another object of the present invention provides a mandrel which extends longitudinally of the drill string adjacent its lower end with a drill bit being secured to the lower projecting end of the mandrel.
  • Helical groove means extend longitudinally of the mandrel in which are engaged rollers that are supported by the drill string whereby spring means supported ty the drill string and abutting the randrel tend to urge the mandrel longitudinally out of the lower end of the drill string into constant contact with the well bore bottom during rotary drilling operations.
  • Seal means between the drill string and the mandrel spaced longitudinally from each end of the helical groove means seal off the groove means and rollers from well fluids.
  • a well bore is illustrated generally by the numeral 10.
  • a drill string represented generally by the numeral 11 extends from the earth's surface into the well bore 10.
  • P mandrel 13 extends longitudinally within the lower end or lower portion of the drill string referred to generally at 14, such mandrel having a longitudinal bore extending therethrough so that well fluids circulated downwardly through the drill string may be discharged out through the drill bit 15 connected to the lower end of the mandrel 13.
  • Cooperating means are provided for supporting the mandrel telescopically within the lower portion 14 of the drill string 11 whereby rotation of the drill string 11 at the earth's surface by means well known in the art may be imparted to the mandrel 13 and drill bit 15 supported on the lower end thereof for drilling the well bore 10.
  • Such cooperating means not only transmits rotation of the drill string 11 through the mandrel 13 to the bit 15, but such cooperating means also accommodates relative rotation and longitudinal movement between the mandrel 13 and the portion 14 of the drill string 11 in which the mandrel 13 extends during drilling operations.
  • the cooperating means includes helical groove means which may include one or more (and preferably three) longitudinally extending left hand grooves represented at 20 on the outer surface of the mandrel 13 as shown in the drawings.
  • the drill string 11 supports roller means 21 which engage within the longitudinal extending groove means 20 as schematically illustrated in Figs. 1, 2 and 4B and as more clearly illustrated in Fig. 58 of the drawings.
  • Spring means 23 surround the lower end of the mandrel 13 and are engaged at one end on the drill string as represented at 24 by any suitable arrangement while the other end is engaged on a sub 13c carried on the lower end of the mandrel 13.
  • the spring means 23 tends to normally urge the mandrel 13 longitudinally to an extended position relative to the surrounding drill string portior 14.
  • a drill bit 15 is threadedly connected to sub 13c and is urged into contact with the bottom 16 of the well bore 10 by the spring means 23 acting on mandrel 13 as above described.
  • rotary drilling operations both on shore and offshore subject the drill string 11 to substantial impact loading when the drill string 11 and drill bit 15 are moved u p off the bottom 16 of the well bore and then reengaged on the bottom 16 of the well bore, such movement being caused by any one of a number of effects.
  • the drill bit 15 next strikes bottom the drill bit may be damaged, and substantial shock loading is applied to the threaded connections of the drill string.
  • Even the normal loads carried by a drill string 11 during rotary drilling operations are substantial and it is desirable to reduce if not completely eliminate any shock loading that may be applied thereto during such drilling operations, as well as reduce any torsional stresses applied throughout what may be a substantial length of drill string extending from the bottom 16 of the well bore to the earth's surface.
  • valve means referred to generally at 30 are shown as being carried on the mandrel in spaced relation to and above the bit 15. While Fig. 2 illustrates the valve means immediately adjacent and above the bit, it can be appreciated that the valve means 30 may be positioned an additional distance above the bit 15 and beneath the lower end lla of drill string 11 by employing a sub (not shown) of suitarle length.
  • roller means 21 as shown in Fig. 5B includes a member 21a secured to the drill string 11 with a spindle or stem 21b projecting inwardly therefrom upon which a roller 21c is rotatably carried and which roller engages in the helical groove means 20. It can be appreciated that there may be a plurality of such roller means 21 spaced longitudinally of the drill string portion 14 for engagement with the helical groove means 20 to accommodate the desired rotational and longitudinal movement between the drill string 11 and mandrel 13 during functioning of the device.
  • a simple rugged construction which may enable an increase of hole depth per hour of drilling time as well as increase the number of hours of drilling time per drilling bit. Additionally, the invention maintains the drilling bit in substantially constant contact with the bottom 16 of the well tore 10 thus overcoming or offsetting any up and down movement caused by ocean swells in off shore operations or up and down movement caused by drill bit chattering or bouncing off the bottom of the hole in either off shore or on shore operations.
  • drilling forces are increased without increasing drill string loading and torsional stresses in the drill string are reduced which consequently reduces any twisting that might otherwise occur in the drill string, especially during those momentary interferences of drilling bit rotation.
  • the series of driving rollers 21 supported by the drill string 11 and engaged in the left hand groove means 20 of the mandrel 13 provides a positive drive between the rotating drill string 11 and the mandrel 13 while permitting the mandrel 13 to telescope u p and down within the drill string 11 to offset movement caused by the ocean swells on off shore locations as well as overcoming bouncing or chattering of the drill bit 15 off the bottom 16 of the well bore in off shore as well as on shore operations.
