Definitions
- the invention relates to a cooling apparatus for a downhole tool and in particular, but not exclusively to a drilling environment.
- Figure 1 schematically shows a typical onshore hydrocarbon well with surface equipment 1, which is located above a hydrocarbon geological formation 2 after some well-bore 3 drilling operations have been carried out.
- a first portion 4 of the well-bore is a cased portion.
- a casing string 5 has been run into this first portion of the well-bore. Cementing operations have been carried out, in this first portion, for sealing the annulus (i.e. the space between the well-bore 3 and the casing string 5).
- a second portion 6 of the well-bore is an open bore hole.
- a third portion 7 of the well-bore is a sensibly horizontal lateral bore hole.
- the surface equipment 1 comprises a plurality of mud tanks and mud pumps, a derrick, a drawworks, a rotary table, a power generation device and various auxiliary devices, etc, which are well known in the oilfield industry domain.
- a drill string 8 couples the surface equipment with a downhole tool, for example a drilling assembly 9.
- the drilling assembly comprises a drill bit.
- the drill string and the drilling assembly comprise an internal conduit through which a drilling fluid 10 circulates.
- the downhole tool may further comprise a logging assembly 11 for performing logging while drilling or measurement while drilling.
- the logging assembly comprises various sensors, detectors, power units, and processing units comprising numerous electronic components.
- the downhole tool further comprises a cooling apparatus 12 for cooling down the electronic components below their conventional maximum operating temperature in order to avoid any failure during operation.
- the cooling apparatus 12 may be based on thermodynamic machines, for example mechanical vapor compression cycles, Stirling engine, inverse Brayton cycle, sorption cycles, etc... Typically, these systems are driven by an electric motor.
- the electrical power may be supplied by either a battery or an alternator turbine.
- an alternator turbine is driven by the drilling fluid circulating inside the internal conduit of the drill string. Such an alternator turbine and drilling assembly are preferred because of the high power output.
- FIG. 2 is a block diagram schematically showing a typical system for cooling electronic components in the downhole tool.
- the cooling apparatus 12 comprises a turbine 13, an alternator 14 and appropriate electronic circuits 15 and 16, an electrical motor 17, and a thermodynamic cooler 18.
- the turbine 13 is coupled to the alternator 14 and, both form an electrical energy generator.
- the turbine 13 rotates when the drilling fluid 10 is circulated within the drill string and downhole tool.
- the alternator 14 driven by the turbine 13 generates an alternative signal, which is delivered to the power supply 15.
- the power supply 15 may comprise a rectification module (e.g. a Graetz bridge) coupled to a power converter (e.g. a rectifier and a step-down converter).
- the power supply 15 delivers an electrical power under the form of a rectified and stepped-down signal (voltage and/or current) suitable for the operation of a motor driving unit 16 connected to an electrical motor.
- the electrical motor 17 drives the thermodynamic cooler 18, for example by alternately compressing/decompressing a fluid, the decompressed fluid being the "cold" source of the thermodynamic cooler.
- One aspect of the invention relates to a cooling apparatus of a downhole tool comprising a turbine driven by a drilling fluid circulating in the downhole tool, a thermodynamic cooler, and a mechanical arrangement driven by the turbine, the mechanical arrangement coupling the turbine and the thermodynamic cooler such that the thermodynamic cooler is mechanically driven by the turbine.
- the mechanical arrangement comprises an actuating cam transforming a rotation of the turbine into an oscillating movement in the thermodynamic cooler.
- thermodynamic cooler is a Stirling cooler comprising a linear piston coupled to the actuating cam.
- the mechanical arrangement comprises a shaft drive transforming a rotation of the turbine into a circular movement in the thermodynamic cooler.
- thermodynamic cooler is a compressor coupled to a heat exchanger.
- the compressor is chosen in the group of compressor comprising the Wankel type compressor, the screw compressor, the scroll compressor, the liquid ring pump, and the membrane pump.
- Another aspect of the invention relates to a downhole tool comprising a cooling apparatus according to the invention.
- Still another aspect of the invention relates to a method comprising: driving a turbine by a drilling fluid circulating in the downhole tool, and coupling, by a mechanical arrangement, the turbine and a thermodynamic cooler such that the thermodynamic cooler is mechanically driven by the turbine.
- the direct turbine driven thermodynamic cooling for downhole use is simple and reliable compared to prior art systems.
- the rotation of the hydraulic turbine driven by the drilling fluid is directly converted to proceed a thermodynamic cycle.
- the mechanical work of the hydraulic turbine mechanically powers the thermodynamic cooler instead of generating and transforming electric power generated by an alternator coupled to the turbine.
- FIG 3 is a block diagram schematically representing a cooling apparatus 12 for a downhole tool (9 and 11 shown in Figure 1 ).
- the cooling apparatus 12 may be positioned closely to the logging assembly (11 shown in Figure 1 ) in order to efficiently cooled down the electronic components of the logging tool.
- the cooling apparatus 12 comprises a turbine 13, a mechanical arrangement 19 and a thermodynamic cooler 18.
- the thermodynamic cooler 18 is coupled to the electronic components, or the printed circuit board comprising the electronic components, or the detector/sensor.
- the turbine 13 is driven by the drilling fluid 10 circulating in the internal conduit of the downhole tool.
- the mechanical arrangement 19 is driven by the turbine 13.
- the mechanical arrangement 19 couples the turbine 13 and the thermodynamic cooler 18.
- the thermodynamic cooler 18 is mechanically driven by the turbine 13.
- FIG. 4 schematically shows a first exemplary embodiment of the cooling apparatus 12.
- the mechanical arrangement 19 comprises an actuating cam 20.
- the actuating cam 20 may be a swash-plate consisting of a disk attached to a shaft, and a cam follower.
- the actuating cam 20 transforms the rotation movement 21 of the turbine 13 into an oscillating movement 22 which drives the thermodynamic cooler 18.
- the thermodynamic cooler 18 is a Stirling cooler 23 comprising a linear piston 24 coupled to the cam follower of the actuating cam 20.
- the oscillating movement of the linear piston is used to proceed a thermodynamic cycle in the Stirling cooler.
- the thermodynamic cycle creates a temperature difference which is used to efficiently cool down the electronic components of the downhole tool.
- FIG. 5 schematically shows a second exemplary embodiment of the cooling apparatus 12.
- the mechanical arrangement 19 comprises a shaft drive 25.
- the shaft drive 25 transforms the rotation movement 21 of the turbine 13 into a circular movement 26 which drives the thermodynamic cooler 18.
- the thermodynamic cooler 18 is a compressor 27 coupled to a heat exchanger 28.
- the compressor 27 may be a Wankel type compressor, a screw compressor, a scroll compressor, a liquid ring pump, or a membrane pump.
- the circular movement of the compressor is used to proceed a thermodynamic cycle in the heat exchanger.
- the thermodynamic cycle creates a temperature difference which is used to efficiently cool down the electronic components of the downhole tool.
