  • Patent number: 10132118
    Abstract: A method and apparatus for a drive unit of a top drive system including a first, second, and third drive gears that are operationally coupled; a motor engagable with the first drive gear; a drive stem having a load coupling and engagable with the second drive gear; and a torque shaft having a torque coupling and engagable with the third drive gear. The drive stem cannot engage with the second drive gear when the torque shaft is engaged with the third drive gear. A method of coupling a drive unit to a tool adapter includes engaging a first drive gear with a motor of the drive unit while engaging a second drive gear with a drive stem of the drive unit; coupling a load between the drive stem and a tool stem of the tool adapter; and coupling a torque between a torque shaft of the drive unit and the tool stem.

  • Patent number: 10094998
    Abstract: A structure for directly leading down the optical unit (OU) from the OPPC (optical phase conductor) cable, by the OU leading-down connector (2) invented recently, is used for separating the plastic-pipe OU from the OPPC cable installed on the tower, avoiding the splicing of fibers on the tower of the old technique. Therefore it is possible to assemble the OPPC cable (1), the OU leading-down connector (2), the preformed armor rod assembly (3), the first link fitting (4), the residual cable rack (5), the second link fitting (6), the insulator string (7) on the ground all together. Then the whole assemble can be erected on to the tower. Just as the conventional overhead power line construction. So it is simple and saving in work.

  • Patent number: 9938772
    Abstract: The disclosure provides a system and process for drilling a subterranean wellbore. An embodiment includes a bottom-hole assembly for a downhole mud motor that incorporates an information sub, such as a measurement-while-drilling or logging-while-drilling tool, at a location below, or down-hole from, the mud motor. The assembly also includes a micronized bit-to-bend length, or a length between a forward end of the assembly's bearing mandrel and a fixed bend in the assembly's housing, of less than or equal to forty inches. The combination of the forward-located information sub and micronized bit-to-bend length allow the driller to rely on real-time data relating to conditions adjacent to the drill bit/bottom of the wellbore and take that real-time drilling data into account in steering the bit along a planned wellbore trajectory. Other embodiments are also disclosed.
