Definitions

  • U.S. Patent No. 8,997,895 entitled“System and Method for Coupling an impregnated Drill Bit to A Whipstock” shows a system and method that facilitate the drilling of one or more lateral wellbores while eliminating one or more trips downhole.
  • the system uses a drilling assembly including an impregnated drill bit or other suitable drill bit.
  • the impregnated drill bit couples to a whipstock by a connector for deployment downhole in a single trip.
  • the connector includes a separation device which facilitates disconnection of the impregnated drill bit from the whipstock once the whipstock is anchored at a desired downhole location.
  • the present disclosure details a method, system, and fabrication method for a bi-mill for milling an opening through a wellbore casing and in a preplanned lateral drilling path in departure from the wellbore axis using helical debris channels and dense milling insert configurations for initiating a lateral bore into a rock formation.
  • a bi-mill for milling an opening through a wellbore casing in initiating a preplanned lateral drilling path in departure from the wellbore axis and through the wellbore casing or wellbore rock formation, and further continuing into underground rock formation outside the wellbore and in the direction of the preplanned lateral drilling path and as guided by a wellbore whipstock.
  • the bi-mil includes an assembly having a lead mill and a follow mill.
  • the lead mill threadably attaches to the follow mill.
  • the lead mill includes a body forming a structural base for the lead mill, and further includes a smooth bore in the lead mill into which a circumferentially-grooved shear bolt is inserted.
  • a threaded end threadably attaches to the wellbore whipstock and with the unthreaded end inserts into the smooth bore.
  • the lead mill further includes a plurality of fluid passageways wherein the smooth bore has a sufficiently shallow depth so as to not intersect with the internal fluid passageways and so as to not exit the distal side of the lead mill.
  • the lead mill further includes an external bore and a retaining pin inserted through the external bore for intersecting the smooth bore.
  • the shear bolt includes a groove, wherein the retaining pin further inserts into the groove for retaining the shear bolt within the smooth bore.
  • the lead mill further includes a nose and at least four fluid passageways leading from a central axial fluid passageway inside the lead mill and exiting a plateau defined as the end portion of the nose with an area perpendicular and obtuse in relation a central fluid passageway of the lead mill.
  • a plurality of debris removal channels form recessed paths within the body and a plurality of exit paths for channeling milled debris away from the lead mill and in the direction of the follow mill.
  • a plurality of milling inserts is positioned on the lead mill and in rows adjacent the debris removal channels for milling through the wellbore casing or wellbore rock formation and into the underground rock formation. At least three rows of milling inserts extend from the center of the plateau down the side of the lead mill in continuity.
  • the lead mill makes efficient use of space with a novel shear bolt cavity and shear bolt retaining pin configuration, permitting a greater total flow area (“TFA”) for debris clearance than in the prior art.
  • TFA total flow area
  • This space-saving configuration also permits extra cutting structure to be placed on the lead mill compared to prior art designs, particularly at lead mill’s nose and plateau area.
  • FIGURES and examples are not meant to limit the scope of the present subject matter to a single embodiment, but other embodiments are possible by way of interchange of some or all of the described or illustrated elements and, further, wherein:
  • FIGURE 2 shows a bi-mill comprised of a lead mill, a threaded tubular connection, and cylindrical inserts on both the lead mill and follow mill;
  • FIGURE 3 shows the lead mill component of the bi-mill in the state of being attached to the upper portion of a whipstock
  • FIGURE 6B shows a section view of the bi-mill, with the shear bolt cavity visible as well as capped shearable nozzles;
  • This disclosure facilitates the exit from the casing, or rock formation, in the absence of casing, and creation of an initial bore over a short distance into the rock formation.
  • a sidetracking or lateral drilling operation begins with what may be referred to as a“wellbore departure” operation.
  • the objective in wellbore departure is to exit from a main wellbore and begin boring a new lateral bore that exits or departs from the main wellbore.
  • shearable nozzle 28 assemblies are also threaded into the plateau of the lead mill.
  • the lead mill’s recessed debris removal channels 38 benefit from three shearable nozzles 28 and a tubular connection hole 32 at the plateau of the lead mill 12.
  • Three shearable nozzles 28 with nozzle ports 34, in addition to a tubular connection hole 32 located at the plateau provide for significantly increased total flow area (“TFA”) at the plateau when compared to the prior art.
  • TFA total flow area
  • the increased TFA provides for maximal upflow of milled debris, and a resultant reduction in required torque, producing a smoother milling operation.
  • the greater TFA and torque reduction provides less opportunity for vibration destructive slip-stick. Slip-stick occurs when a mill or bit binds during workstring rotation, stores energy until it releases, and then releases with unwanted rotational acceleration, causing vibratory and potentially destructive effects.
  • the lead mill and follow mill bodies may have their recessed debris removal channels 38 timed to match each other, enabling a more efficient milling and debris removal operation.
  • the lead mill and follow mill may have the same number of debris removal channels and furthermore these debris channels may be aligned, such that debris channels of the lead and follow mills are the same in number and furthermore the trailing ends of debris channels from the lead mill align with leading ends of debris channels from the follow mill for improved flow of debris and for smoother milling.

Abstract

La présente invention concerne une bi-fraise qui faise une ouverture à travers un tubage de puits de forage dans un trajet de forage latéral préplanifié en écart de l'axe du puits de forage et à travers le tubage de puits de forage ou la formation rocheuse et dans la direction du trajet de forage. La bi-fraise permet d'augmenter l'élimination des débris et les surfaces de coupe et comprend un ensemble qui a une fraise avant et une fraise suiveuse et se fixe au sifflet déviateur de puits de forage. La fraise avant comprend en outre des voies de passages de fluide qui mènent à partir de la fraise avant et sortent du nez de la fraise avant. Des canaux d'élimination de débris canalisent des débris fraisés pour les éloigner de la fraise avant et dans la direction de la forme de fraise suiveuse en configuration hélicoïdale pour guider des débris fraisés par des pièces rapportées de fraise avant le long des canaux d'élimination de débris. La fraise avant et la fraise suiveuse continuent le fraisage à travers le tubage de puits de forage et dans la formation rocheuse souterraine sur une distance suffisante pour initier le trajet de forage préplanifié.
