  • Patent number: 10399258
    Abstract: There is disclosed herein a method of designing a mold, the mold being at least part of a unitary body to be formed from a plurality of layers by 3D printing, the method including defining an inner surface of the mold corresponding to at least part of an outer surface of an object to be molded in the mold; selecting a first material from which at least part of the mold is to be printed; and selecting a second material from which at least another part of the mold is to be printed, the second material having a higher thermal and/or electrical conductivity than the first material, wherein at least one of the layers from which the mold is to be formed by 3D printing includes areas to be printed from each of the first and second materials.

  • Publication number: 20190145184
    Abstract: An example method for dynamic wear prediction for a drill bit with a cutting structure may include receiving at a processor of an information handling system an unworn profile of the cutting structure and a diamond distribution of the cutting structure. The diamond distribution may include a three-dimensional diamond distribution characterized by radial and axial position on the drill bit. The method may include calculating a final predicted wear profile of the cutting structure based, at least in part, on the unworn profile and the diamond distribution. The method also may include calculating iterations of intermediary wear profiles based, at least in part, on the previous wear profile and the diamond distribution. The final predicted wear profile may indicate a fully worn portion of the cutting structure. A usable life for the drill bit may be determined based, at least in part, on the final predicted wear profile.

  • Patent number: 7958951
    Abstract: An underreaming tool may include a tubular body, a drive tube, at least one blade element (“the blade element”), at least one wedge element (“the wedge element”), and a stop mechanism. The drive tube may include at least one longitudinal groove (“the longitudinal groove”) axially disposed along a length of the drive tube. The wedge element may include a first side having at least one lateral projection (“the lateral projection”) configured to axially slide into the longitudinal groove to couple the wedge element to the drive tube. The stop mechanism comprises a threaded sleeve configured to screw onto the drive tube to lock the wedge element in the longitudinal groove once the lateral projection is slid into the longitudinal groove.

  • Patent number: 7946362
    Abstract: A matrix drill bit and method of manufacturing a matrix bit having back raked cutting elements is disclosed. In one aspect, a matrix drill bit for well drilling includes a matrix bit body that has a front area in a direction of drilling and two or more diamond impregnated cutting blades protruding from the front area of the matrix bit body. The cutting blades each have a front external surface protruding from the front area of the matrix bit body and present a plurality of back raked downhole interface surfaces in the direction of drilling. The downhole interface surfaces span a leading face and a trailing face where the leading face extends to a first height and the trailing face extends to a second height and the first height is greater than the second height.

  • Publication number: 20080028891
    Abstract: Three dimensional printing equipment and techniques may be used in combination with three dimensional design data associated with well drilling equipment and well completion equipment to form molds associated with manufacture of such equipment. For example, such molds may be used to form a bit body or other components associated with a rotary drill bit. For some applications composite or matrix materials may be placed in the mold to form a matrix bit body. Heat transfer characteristics of the mold may be optimized for heating and/or cooling of the matrix materials to provide optimum fracture resistant (toughness) and optimum erosion, abrasion and/or wear resistance for portions of the bit body. Such molds may also be used to form steel bit bodies associated with fixed cutter rotary drill bits and other components associated with a wide variety of well drilling equipment and well completion equipment.
