  • Patent number: 11421484
    Abstract: A drill bit comprises a bit body having a longitudinal axis and a blade extending radially outward from the longitudinal axis along a face region and axially along a gauge region. A gauge region includes a cutting element located proximate to an uphole edge of the blade in the gauge region. A remainder of the gauge region is free of cutting elements mounted thereon. A method of drilling a borehole comprises rotating the bit about the longitudinal axis, engaging a formation with cutting elements mounted to the face region, and increasing a lateral force applied substantially perpendicular to the longitudinal axis such that the cutting element engages the formation and such that side cutting exhibited by the tool is initially minimal and substantially constant and subsequently increases in a substantially linear manner with increasing lateral force.

    Abstract: A vibrating type hard rock cutting mechanism with a function of directional high-speed abrasive jet advanced slitting includes a disc-shaped hob, a cutting main shaft and a valve plate. When the vibrating type hard rock cutting mechanism works, an outlet of a high-pressure abrasive jet generating system is communicated to a cutting mechanism abrasive jet inlet. An abrasive jet enters an abrasive jet nozzle through flow channels in the valve plate, the cutting main shaft and the disc-shaped hob and forms a directional high-speed abrasive jet. The cutting main shaft is directly driven to rotate by an axial permanent magnet motor. The cutting mechanism enables the disc-shaped hob to vibrate under the action of a vibration motor. A macro crack is formed on a rock mass by rotating the abrasive jet. The rotating disc-shaped hob can be wedged into the formed crack in a vibration manner by swinging the cutting mechanism.

The cemented matrix material is formed from a tungsten carbide powder, a shoulder powder, and a binder material, wherein at least one of the tungsten carbide powder or the shoulder powder is absent of any free tungsten. The blank, which optionally may be coated, is substantially cylindrically shaped and defines a channel extending from a top portion and through a bottom portion of the blank. The absence of free tungsten from at least one of the tungsten carbide powder or the shoulder powder reduces the reaction with iron from the blank, thereby allowing the control and reduction of intermetallic compounds thickness within the bondline.

Varying the nozzle geometry remotely without the need to pull the drill string outside the hole has obvious advantage. Changing the nozzle glow geometry results in changing the nozzle HSI which is beneficial to optimize drilling different rock formations in different drilling environment. There are many concepts to vary the nozzle size while drilling. The drill bit nozzle geometry can be varied by causing a change of at least one physical property of the environment. The variable geometry nozzle is not limited to drill bit, it can be placed within the inner flow passage or between the inner flow passage and annular flow passage for controlling flow profile within a wellbore, a tubular string or a flow conduit.

  • Patent number: 8485283
    Abstract: A drill bit including a body section. The body section defines a body proximal end and a longitudinally opposed body distal end, and a body passageway extending longitudinally therethrough for receiving a fluid and conveying the fluid through the body section. An annular crown section extends longitudinally from the body section, the crown section defining a crown distal end and a longitudinally opposed crown proximal end, the crown section extending distally from the body section, the crown section defining a crown passageway extending longitudinally therethrough and in fluid communication with the body passageway. A flow directing component cooperates with the crown section to define a fluid flow channel extending through the crown section radially outwardly from the crown passageway, the fluid flow channel being self-modifiable upon the crown section reaching a predetermined wear threshold so as to modify a flow of the fluid through the fluid flow channel.

    Abstract: A horizontal directional drilling sonde housing has a cavity for receiving a sonde. Signal channels extend from the cavity to an exterior of the housing. A polymer lines at least part of the cavity and fills the signal channels. The drilling tool has a bit body and a drilling body. The two bodies have respective lateral surfaces which engage each other to prevent the transverse movement of the drilling body relative to the bit body during operations. The drill bit has a forward extending drill tooth, which drill tooth is removable from a bore. A spacer is located in the bore between the bottom end of the bore and the tooth. The drilling bit has buttons located on the side in a spiral configuration about a longitudinal axis of the bit.
