Abstract

1,156,134. Measuring bit pressure electrically; dynamometers. BRISTOL SIDDELEY ENGINES Ltd. April 26, 1967 [April 27, 1966], No.18516/66. Headings G1N and G1W. [Also in Division E1] Optimum bit penetration is obtained during drilling by applying a higher bit weight than necessary, drilling with the draw-works brake 63 fully applied, measuring the tension and the rate of change of tension in the deadline 26 by means of sensors 65, 28 respectively, and whilst still continuing drilling operating the brake to maintain a tension in the deadline corresponding to that for which the rate of change of tension is a maximum. Apparatus for measuring the rate of change of tension includes a drum (66 Fig. 4, not shown) rotatable in an anchorage (25), and a member (68) between an arm (67) on the drum and the anchorage and arranged to cause fluidpressure variations in a line (69) in response to the change of tension. The line is connected to a capsule (70) and a vent (75) having a controlled leakage so that a pointer driven by the capsule indicates rate of change of tension. In alternative apparatus Fig. 2 (not shown) the deadline passes between pulleys (33) and a block (34) movable relative to the pulleys. The block moves as a result of change in deadline tension and alters the load on a stack of Piezo-electric discs (34) causing a current proportional to the rate of change of tension to flow in a restistance (45a). The volt drop over the resistance passes to an amplifier (46) and is indicated on a dial (29). A capacitor (45) is provided for damping transient distrubances. The brake may be operated manually following observations of the pointers on dials 27, 29, and the pointers together with a third pointer may sweep a single dial calibrated in bit weight units, the arrangement being that the third pointer indicates the bit weight for optimum penetration. In automatically controlled drilling a timer 89 causes a control 92 to relax the brake until the higher bit weight (deadline tension) is reached. Increase in signal from the sensor 65 detecting the bit weight (deadline tension) causes the control to fully apply the brake when the higher bit weight is reached. The sensor 28 gives a rate of change of bit weight (rate of change of deadline tension) signal which is differentiated in a device 87 and when this signal reaches a maximum the device sends a signal to the control which registers the bit weight at that moment and operates the brake to maintain that weight during drilling. After a given time the timer resets the device 87 and relaxes the brake to allow the cycle to be repeated
