Definitions

  • the frame carried by the drilling platform extends between end walls 18 and 20, and includes a plurality of guide elements 40 in the form of round tubular elements which provide a track to guide the movement of a carriage, designated generally as 42.
  • Means for advancing carriage 42 longitudinally along the frame includes a screw drive having a pair of threaded rods 46 which are threadably received in collars 48 carried by carriage 42.
  • Suitable motor 50 are carried by end wall 20 to rotate screw drive rods 46 and advance carriage 42 either forward or rearward in reciprocating linear motions.
  • Other means for advantageously advancing the carriage along the platform may be utilized according to the invention. Due to the relative short length of the drilling platform, a hydraulic cylinder may be utilized. The cylinder may be attached to end wall 18, and the piston may be attached to carriage plate 42.
  • This control delivers a suitable motive fluid to a turbine motor designated generally as 62 contained in drilling head B, as can best be seen in Figure 4.
  • the motive fluid goes through hollow shaft 52a and through the hollow interior of stems 26 of drill string 28.
  • the drill string is rotated and pushed forward by carriage 42 as drilling head B drills the earthen bore.
  • carriage 42 reaches its forward extent, the hydraulic fluids are cut off, stem 26a is removed from coupling 54.
  • Carriage 42 is then moved rearward to its rearward most position, a new stem section 26a is coupled to chuck 54 at one end and joined to the previously coupled drill stem at the opposite end.
  • the motor fluids are then reestablished and pushing of the drill string through the earthen bore again initiated by the advance of carriage 42.
  • Drilling stems 26 typically come in five, ten, or fifteen foot lengths which are threaded together for joining.
  • Drill bit 72 may be any suitable drill bit such as a thermally stable diamond bit.
  • Such a bit includes a center bore 72b through which the slurry which drives mud motor 62 exits to the center of the bit as shown by arrows 88. The slurry then returns through slots 72c formed in the drilling bit rearward through the clearance to the overcut space 86 in bore 32 and exits through the annular exit space 30 formed in end wall 18 of the drilling platform cartridge ( Figure 3).
  • the angular rate sensor is a single axis rectilinear momentum rate sensor which senses the angular rate about a single axis. Any suitable rectilinear rate sensor may be utilized. As illustrated, an angular rate sensor manufactured by Humphrey, Inc., of San Diego, California is illustrated. It is to be understood, of course, that other angular rate sensors, such as a rate gyro may also be utilized in accordance with the invention.
  • Single axis angular rate sensor 92 utilizes a gas pump and measures the transport time of the gas from a nozzle to a sensor wire. When the sensor body rotates the distance the gas travels and the transport time change. The changes are converted into angular rates about the sensing axis.
