The drill bit 15 may be rotated by either the drill pipe 13 or by a rotary mud motor,(not shown).
- a drill stem is shown within the borehole and comprises the drill pipe 13 connected at the upper end through a square Kelly Bar 16 to a swivel 17.
- the swivel 17 is suspended from a traveling block hook 18, a traveling block 19, drilling lines 20 and a crown block 21 located in the top of a derrick 22.
- the square Kelly Bar 16 passes through conventional gripping means in a rotary drilling table 25 which is supported in the customary manner upon the derrick floor supports.

- a drilling fluid circulation passage extends from the discharge connection 35 of a drilling fluid circulation pump 36, through connecting pipes 37, a riser 38, a suitable flexible connection 39, the swivel 17, the Kelly Bar 16, down the drill pipe 15, through the drill collar 14 and out an opening 40 in the drill bit 13.
- the fluid travels back up the lower uncased portion of the borehole and through the surface casing 12.
- the upper end of the surface casing 12, which provides a return path for circulating drilling fluid from the open borehole, is provided with a lateral outlet pipe 42 which extends to and discharges into the drilling fluid reservoir 32.
- the drilling fluid circulating pump 36 takes suction through a pipe 38 from the body of drilling fluid 39 contained in the mud reservoir 40.
- a surge chamber 45 may be connected to the discharge connection 35 of the drilling fluid circulating pump 36 for the purpose of smoothing out or reducing the pump discharge pressure fluctuations.
- Attached to the lower end of the drill pipe 13 is a special sub 51, the bottom of which is connected to the drill bit through a drill collar 52.
- the sub 51 is preferably located in the region of the borehole 10 from which environmental parameter measurements are to be made.
- FIG. 2 there is shown a longitudinal cross-section view of the special sub 51 which includes a cylindrical outer casing 53 preferably formed from a section of steel drilling pipe having a female threaded opening 54 at the upper end and a male threaded opening 55 at the lower end.
- a cylindrical telemetry instrument package 56 which includes (1. c. to d. c. converter 57 is positioned within and in axial alignment with the casing 53.
- the instrument package 56 is attached to and spaced from the inner walls 58 of the casing 53 by means of a plurality of circumferentially spaced struts 59 to define an annular space 60 therebetween.
- the lower end of the package 56 includes an internally threaded socket 61, which is electrically isolated from the body of the package 56 but electrically connected to one input terminal (not shown) of the d. c. to d. c. converter 57.
- Attached to the lower end of the package 56 is a generally cylindrical, axially positioned electrode 62, formed from a material, such as magnesium, having adifferent electrochemical potential than that of the outer casing 53.
- the electrode 62 is attached to the package 56 by means of an upper threaded section 63 which engages the socket 61.
- the body of the electrode 62 is electrically isolated from the package 56 by an insulative disk 64.
- the electrode 63 also includes a lower threaded section 65 which is attached to an insulative, streamlining dome 66.
- a flow of drilling mud enters the sub 51 through the top opening 54, flows through the annular space 60 in the direction of arrows 70 and exits through the bottom opening 55.
- the electrode 62 includes a plurality of circumferentially spaced, radially extending, longitudinally disposed slots 67.
- the slots 67 serve to increase the effective surface area of the electrode 62 and channel drilling fluid flowing through the annular space 60 to keep the electrode surfaces flushed and cleaned of any polarizing film that might tend to develop.
- the power supply comprises a primary cell using the magnesium electrode 62 as a sacrificial anode, the steel of the drill pipe casing 53 as a cathode, and the conductive drilling mud in the annular space as an electrolyte.
- magnesium stands at about a plus 2.40 volts in the electromotive series of elements and steel ranges from about a plus 1.15 volts to a plus 1.3 volts
- the electrochemical potential of the resultant primary cell is from about 1.1 to 1.25 volts.
- This potential when coupled to the input terminals of the d. c. to d. c. converter 57 produces an output voltage on the order of 12 volts, suitable for driving transistor circuitry in the telemetry instrument package 56.
- the internal resistance of the primary cell is inversely proportional to the exposed areas of the anode and cathode and directly proportional to the resistivity of the electrolyte in contact with both electrodes.
- the effective life of the primary cell is directly proportional to the quantity of magnesium in the anode electrode 61 which may be six months or more in normal operation. Power outputs on the order of 15 to 20 watts may be achieved with the system of the present invention.
- a mud having a resistivity on the order of 10-15 ohm-cm or less is used for the electrolyte in the power supply of the present invention in order to achieve usable power levels on the order of 10 watts or more.
- FIG. 4 is a graph of maximum power output in watts as a function of the length of the magnesium electrode for various resistivities of drilling mud. These curves were calculated for a magnesium-iron cell with an anode electrode having a diameter of 3 inches. The curves are further based on an open circuit output voltage from the cell of 1.15 volts and a surface resistance of the magnesium electrode as calculated by the following modified Dwights formula:
- FIG. 5 is a graph of expected cell life in years for a cell operating at maximum output power as a function of the length of the magnesium electrode for various resistivities of drilling mud. These curves were calculated for a magnesium iron cell with anode electrode 3.1416 sq. in. in cross-sectional area and a specific gravity of 1.74. Also used was a rule of thumb that 17 pounds of magnesium will last 1 year as a sacrificial anode with a 1 amp drain. As can be seen from FIG. 5, for mud resistivities on the order of 10 ohm-cm, a life expectancy of 6 months or more can be anticipated.
- an efficient down-hole power supply can be constructed by arranging a cylindrical anode coaxially within a steel drilling pipe, serving as the cathode, and flowing drilling mud through the annular space there between.
- a potential is produced from the cell depending on the relative electrochemical potentials of the anode and cathode materials.
