Description

TECHNICAL FIELD

[0001] The present disclosure relates to a rig. It further relates to a method for cooling at least one component that generates heat and / or heating at least one component that needs heat on a rig. BACKGROUND

[0002] A flushing medium can be used on, for example, a blast hole rig or a survey rig for flushing away debris or cuttings in a borehole. The debris or cuttings can be material that is generated when drilling the borehole. The flushing medium can be a gas, a liquid or a combination of a gas and a liquid.

[0003] The rig can comprise a tank for storing a flushing medium that can be used for flushing. The flushing medium is used for flushing away the debris or cuttings and it can be used for suppressing dust formation and stabilizing the borehole.

[0004] The flushing medium is conveyed to the nozzle via a channel and the flushing medium is flushed into the borehole through the nozzle. The flushing medium can be combined with another flushing medium before being flushed through the nozzle.

[0005] The rig comprises several components that need to be cooled. Such components can be electrically powered, hydraulically powered, mechanically powered and / or pneumatically powered components. The cooling of the components can be done with air, oil and / or water cooling, in which water is used in a closed system.

[0006] When electrifying a rig, there are challenges with cooling battery systems, hydraulic systems, fuel cells and electrical systems. Large, heavy and space demanding coolers are needed. Obtaining service and maintenance will require expensive solutions. Excess capacity to meet cooling requirements during effect peaks (e.g. stability) can be expensive. Electrical systems work at lower temperatures than diesel engines, which makes the temperature difference lower, i.e. cooling electrical systems will require more. Therefore, it is desirable to improve the cooling of a rig comprising electrical systems. Furthermore, it is desirable to use components in cold environments where the components can need to be heated. SUMMARY

[0063] Rigs are becoming electrified in order to reduce the use of e.g. diesel engines. The use of an electrified rig reduces the impact on the environment and can further improve the environment for the workers. A rig comprises several components that can need to be cooled, such as electrical components, hydraulic components, mechanical components, pneumatic components or fuel cells. When electrifying a rig, it can be challenging to cool the components of the rig. Electrical systems work at lower temperatures than diesel engines and the temperature difference to the environment will be lower. This makes the cooling of the electrical systems more demanding. Furthermore, it can be difficult to use components such as batteries in e.g. cold climates. The batteries can need to be heated in order to be able to work, or at least work efficiently.

[0064] According to the present disclosure, a rig is provided comprising a flushing system comprising at least one nozzle to provide a first flushing medium and at least one flushing channel arranged to transport the first flushing medium from at least one flushing medium storage to the at least one nozzle. The at least one flushing medium storage can be arranged to store the first flushing medium. The flushing medium storage can be comprised on the rig or the flushing medium storage can be separate from the rig. The first flushing medium can be combined and mixed with a second flushing medium. The first flushing medium can comprise a gas and / or a liquid. Furthermore, the first flushing medium can be a liquid that can be transformed into a gas, e.g. when leaving the flushing medium storage or leaving the nozzle. The second flushing medium can comprise a gas and / or a liquid to flush away debris or chips in the borehole. The gas used as the second flushing medium can be compressed air. The debris or chips can be material produced when drilling the borehole. The first flushing medium can also be used to suppress dust formation and stabilize the borehole. The first flushing medium can be used as the second flushing medium.

[0065] Figure 17 A rig 10 is shown in Fig. 1 and will be referred to in the following text. Figure 17 The rig 10 of the embodiment of Fig. 1 comprises a component 4 that generates heat and a component 5 that needs heat. Two components are shown, but several components can be used or only one component can be used. Figure 17An example of a drill rig 10 is described. A tank 1 is comprised on the drill rig 10 and arranged for storing a first flushing medium. In some examples of the embodiments herein, the tank 1 is comprised separately from the drill rig 10, such as positioned, and can then be a tank, reservoir, basin, pool, dam or pond. The drill rig 10 comprises a flushing system (not shown in Figure 17 ) wherein the flushing system comprises a nozzle 32 to provide the first flushing medium and a flushing channel (not shown in Figure 17 ). The tank 1 is comprised on the drill rig 10. When a worker starts a work shift with the blast hole drill rig 10, the tank 1 of the blast hole drill rig 10 is filled with the first flushing medium. In the area of use of the blast hole drill rig, it is normally not possible to refill the tank 1 or to continuously provide the blast hole drill rig 10 with the first flushing medium for flushing the borehole. The blast hole drill rig 10 will travel or be transported to the work area. During the work shift, the first flushing medium will be used for flushing, or it can be used for dust suppression and stabilizing the borehole, and the first flushing medium will be sprayed or flushed through the nozzle 32. The first flushing medium can also be provided in the nozzle 32 together with the second flushing medium. When the first flushing medium is sprayed through the nozzle 32 and the first flushing medium is transported from the tank 1 to the nozzle 32, the first flushing medium can for example cool a component 4 that generates heat, or the first flushing medium can for example heat a component 5 that needs heat. The flushing system can enhance the cooling of the components of the drill rig 10 that generate heat. Alternatively, the flushing system can enhance the heating of the components of the blast hole drill rig 10 that need heat. The first flushing medium in the tank 1 can be consumed during the work shift. The blast hole drill rig 10 can be transported to a location where the tank 1 can be refilled. Alternatively, a supply vehicle can be transported to the blast hole drill rig 10 to refill at least one tank 1. As a further alternative, at least one tank 1 can be refilled when starting the next work shift. The tank 1 has been disclosed in this embodiment, but in other examples of the embodiments, the flushing medium storage can be a reservoir, basin, pool, dam or pond.

[0066] For a survey drill rig, the flushing medium storage can for example be comprised separately from the drill rig. The flushing medium storage separately from the drill rig can for example be a tank, reservoir, basin, pool, dam or pond. The first flushing medium will be used in the same way as disclosed above for the blast hole drill rig. For a survey drill rig, a reservoir can then be transported to the drill rig and the medium of the reservoir used as the first flushing medium as disclosed above.

[0067] In Figures 1-16 several embodiments of the present disclosure comprising a flushing system are disclosed, which will be described below. The flushing system in the figures is schematic and the embodiments can also comprise for example additional components and additional channels.

The flushing channel is connected to the at least one flushing medium storage 1. The at least one flushing medium storage 1 can be comprised on the rig 10 or can be separate from the rig. The flushing medium storage can be arranged to store the first flushing medium. The rig 10 comprises at least one component 4 that generates heat during use of the rig 10 and / or at least one component 5 that requires heat.

[0070] The drilling rig 10 can be a blast hole drilling rig, or the drilling rig can be an exploration drilling rig.

[0071] At least a part of the heat generated by the at least one component 4 that generates heat can be transferred to the first flushing medium or to the closed loop channel medium. The first flushing medium of the flushing system can be arranged to at least partly cool the at least one component 4 that generates heat.

Several channels can be arranged for cooling and heating components on the drilling rig. Some embodiments of this disclosure will be described below. The accompanying drawings are schematic. Figures 1 to 16 The present invention discloses a flushing system including a flushing channel 3 and a nozzle 2. A flushing media storage device 1 is also disclosed. The flushing media storage device 1 may be included (e.g., located on) the drill rig 10 or separate from the drill rig 10. Furthermore, embodiments may include at least one component 4, 5, additional channels, such as optional at least one circulation channel 8, 9, or optional at least one closed-loop channel 6, 7. The drill rig 10 is not shown in these figures. A borehole 15 is illustrated in the figures.

[0073] Figure 1 A flushing system according to embodiments of the present disclosure is disclosed. The disclosed flushing system includes a flushing channel 3 and a nozzle 2. A flushing media storage device 1 is disclosed in the figures. The nozzle 2 can be located in the area of ​​the borehole 15 during use to flush the borehole 15. However, the nozzle can also be used to suppress dust in the environment and does not necessarily need to be used in the borehole area. Figure 1 In one embodiment, the flushing channel 3 is arranged to cool the heat-generating component 4. The flushing channel 3 is arranged such that heat generated by the heat-generating component 4 is transferred to a first flushing medium within the flushing channel 3. The flushing channel 3 delivers the first flushing medium to the nozzle 2. While the first flushing medium is being delivered to the nozzle 2 through the flushing channel 3, the component 4 can be cooled, and cooling can be performed while the component is in use. Cooling requirements are likely greatest when flushing is performed via a drilling rig.

[0074] For example, the cooling requirement may be high when the drilling rig's engine is operating. Simultaneously, when drilling is being performed, flushing of the borehole can be used, and cooling of the drilling rig's engine will also be implemented concurrently. That is, the cooling requirements during drilling will be matched to the use of the flushing system.

[0075] according to Figure 1 In one embodiment, the rinsing system is arranged to cool the heat-generating component 4. Figure 1 The diagram schematically illustrates a flushing medium channel 18 for providing a second flushing medium. The flushing medium channel 18 and the flushing channel 3 can be combined in a suitable manner and at suitable locations within the channels. At least one flushing medium channel 18 and at least one flushing channel 3 are connected to a common channel for providing a mixture of the second flushing medium and the first flushing medium.

[0076] Figures 1 to 16 Embodiments of this disclosure are illustrated, including a flushing system. Furthermore, flushing media storage devices, components, and channels are also shown in the embodiments. In the following description of the figures, some parts of the embodiments are not referred to in all figures. The embodiments are merely examples.

[0077] Furthermore, Figure 2 The embodiment discloses a flushing system and discloses a flushing medium storage 1. The embodiment comprises a component 5 that requires heat. The first flushing medium in the flushing medium storage 1 or in the flushing channel 3 needs to have a temperature that is high enough to heat the component 5. This can be achieved by heating the first flushing medium in the flushing medium storage 1. An alternative is that the flushing medium storage 1 is comprised in an area that is warmer than the location of the component 5. Furthermore, the first flushing medium in the flushing channel 3 needs to have a temperature that is higher than the temperature of the component 5 at the location of the component 5. According to Figure 2 The embodiment of the flushing system is arranged for heating the component 5 that requires heat.

[0078] In Figure 3 The embodiment discloses a flushing system and discloses a flushing medium storage 1. Figure 3 The embodiment further comprises an optional circulation channel 8. The circulation channel 8 is arranged to transport the first flushing medium from the flushing medium storage 1 and return it to the flushing medium storage 1. The component 4 that generates heat is arranged such that the heat generated by the component 4 is transferred to the first flushing medium in the optional circulation channel 8. The first flushing medium is transported back to the flushing medium storage 1 where the temperature of the first flushing medium will increase. The first flushing medium of the flushing medium storage 1 is transported to the nozzle 2 via the flushing channel 3. The function of the first flushing medium for flushing is not affected by the temperature increase. In Figure 3 A heat exchanger 50 is schematically shown in Figure 3 In this embodiment in Figure 3 The heat exchanger 50 can be used in further embodiments, but is only shown in

[0079] Figure 4 The embodiment discloses a component 5 that requires heat. The embodiment discloses a flushing system and discloses a flushing medium storage 1. The embodiment further comprises an optional circulation channel 8. The optional circulation channel 8 is arranged such that heat is transferred from the first flushing medium in the optional circulation channel 8 to heat the component 5 that requires heat. The first flushing medium of the flushing medium storage 1 can have a temperature that is higher than the temperature of the component 5 or the first flushing medium of the optional circulation channel can have a temperature that is higher than the temperature of the component 5 at the location of the component 5. The first flushing medium that is transported in the flushing channel 3 is transported to the nozzle 2 and can be used for flushing the borehole 15.

[0080] Figure 5An embodiment is shown in which the optional first circulation channel 8 is arranged such that heat generated by the at least one component 4 generating heat is transferred to the first flushing medium of the optional first circulation channel 8. The optional second circulation channel 9 is arranged such that heat is transferred from the first flushing medium of the optional second circulation channel 9 to the at least one component 5 requiring heat. The component 4 generating heat is cooled and the component 5 requiring heat is heated. The cooling of the component 4 and the heating of the component 5 can be performed simultaneously.

[0081] The cooling and heating can alternatively be performed separately. The cooling of the component 4 can be performed and the heat generated from the component 4 will be transferred to the first flushing medium of the optional first circulation channel 8. During this time the optional second circulation channel 9 will be closed from communication with the first flushing medium of the flushing medium storage 1. When the first flushing medium of the optional first circulation channel 8 is transported back to the flushing medium storage 1 the temperature of the first flushing medium in the flushing medium storage 1 will increase. After a period of time the flow of the first flushing medium in the optional first circulation channel 8 is stopped by closing the optional first circulation channel 8 from communication with the first flushing medium of the flushing medium storage 1, the optional first circulation channel 8 is arranged such that heat generated by the component 4 is transferred to the first flushing medium of the first circulation channel 8. Then the optional second circulation channel 9 will be opened and the first flushing medium of the circulation channel 9 can be transported to and from the flushing medium storage 1. The optional second circulation channel 9 is arranged to heat the component 5 requiring heat while the first flushing medium in the optional second circulation channel 9 is transported from and back to the flushing medium storage 1. When the first flushing medium of the optional second circulation channel 9 is transported back to the flushing medium storage 1 the temperature of the first flushing medium in the flushing medium storage 1 will decrease. The closing and opening of the optional circulation channels 8, 9 can be performed with control valves 11. The control valves are shown schematically in the figures and can be arranged in other positions. Figure 5 The embodiment of figure 1 shows the control valves 11 as an example and the control valves are not necessary. The control valves can also be used in other embodiments, for example in the embodiments of the other figures.

[0082] The optional at least one circulation channel 8, 9 transports the first flushing medium from and back to the at least one flushing medium storage 1. The flushing medium storage 1 has an opening where the optional circulation channel 8, 9 is connected to the flushing medium storage 1 and the first flushing medium can be transported to and from the optional at least one circulation channel 8, 9 via the opening. Each end of the circulation channel 8, 9 is connected to an opening of the flushing medium storage 1. The opening can be arranged in all embodiments comprising a circulation channel 8, 9.

[0083] The present disclosure can comprise a closed loop channel 6, 7. A closed loop channel for example means that the first flushing medium cannot enter the closed loop channel 6, 7, or that the closed loop channel medium cannot flow out of the closed loop channel 6, 7. The closed loop channel medium of the closed loop channel 6, 7 is separated from the first flushing medium of the at least one flushing medium storage 1.

[0084] In Figure 6 , an embodiment showing a flushing system is disclosed and the embodiment further comprises a flushing medium storage 1 and a closed loop channel 6. The closed loop channel 6 is a closed loop, which means that the closed loop channel medium will only circulate in the closed loop channel and not be in medium connection with the first flushing medium of the flushing medium storage 1. The first flushing medium cannot enter the closed loop channel 6 from the flushing medium storage 1 and the closed loop channel medium of the closed loop channel 6 cannot reach the flushing medium storage 1 from the closed loop channel 6. The closed loop channel 6 is arranged such that heat generated by the component 4 is transferred to the closed loop channel medium in the closed loop channel 6. The closed loop channel 6, 7 can pass through the flushing medium storage 1. A part of the closed loop channel 6, 7 passes through the flushing medium storage 1 by the closed loop channel 6, which is visible in Figure 6 , the closed loop channel 6 has a part that extends in the flushing medium storage 1. Furthermore, the flushing medium storage 1 has an opening, wherein at least one closed loop channel 6, 7 can enter and leave the flushing medium storage 1 to pass through the flushing medium storage 1. This can also apply to other embodiments comprising a closed loop channel.

[0085] Furthermore, according to an embodiment, Figure 7 A component 5 requiring heat is disclosed. The closed loop channel 6 is arranged such that heat is transferred from the closed loop channel medium in the closed loop channel 6 to heat the component 5 requiring heat. The first flushing medium of the flushing medium storage 1 can have a higher temperature than the temperature of the component 5, or the closed loop channel medium of the closed loop channel 6 can have a higher temperature than the temperature of the location of the component 5. Then, the closed loop channel medium of the closed loop channel 6 can heat the component 5 requiring heat.

[0086] In Figure 8 , an embodiment comprising two optional closed loop channels 6, 7 is shown. Figure 8 An embodiment is disclosed, wherein a first closed loop channel 6 is arranged such that heat generated by the component 4 generating heat is transferred to the closed loop channel medium of the closed loop channel 6. Furthermore, a second closed loop channel 7 is arranged such that heat is transferred from the closed loop channel medium of the second closed loop channel 7 to a component 5 requiring heat. Cooling of the component 4 and heating of the component 5 can be performed simultaneously.

[0087] The heat transfer in the first closed loop channel 6 and the heat transfer in the second closed loop channel 7 can alternatively be performed separately. Cooling of the component 4 can be performed and the heat generated from the component 4 will be transferred to the closed loop channel medium of the optional first closed loop channel 6. During this time the closed loop channel medium can stop flowing in the second closed loop channel 7. When the medium of the first closed loop channel 6 is transported in the first closed loop channel 6 through the flushing medium storage 1 the temperature of the first flushing medium in the flushing medium storage 1 will increase. The closed loop channel medium will be transported in the first closed loop channel 6 which will pass the flushing medium storage 1 in the first closed loop channel 6. After a period of time the closed loop channel medium in the first closed loop channel 6 which is arranged to cool the component 4 can stop flowing in the first closed loop channel 6. Then the closed loop channel medium in the second closed loop channel 7 can start flowing through the second closed loop channel 7. The second closed loop channel 7 is arranged such that the closed loop channel medium of the second closed loop channel 7 heats the component 5 which needs heat. When the medium of the second closed loop channel 7 is transported in the second closed loop channel 7 through the flushing medium storage 1 the temperature of the first flushing medium in the flushing medium storage 1 can decrease. The stopping and starting of the flow of the closed loop channel medium of the optional closed loop channels 6, 7 can be performed with control valves. The control valves can be arranged in a similar way as shown in Figure 5

[0129] The rig 10 according to the present disclosure can comprise more than one flushing system, several components 4 that generate heat and several components 5 that require heat. If there are several components, they can be cooled or heated with the same channel or different channels.

[0130] Heat from the first flushing medium passing from the component 4 to the flushing channel 3, the first flushing medium in the optional circulation channel 8, 9 and / or the closed loop channel medium in the optional closed loop channel 6, 7 can be transferred by at least one of conduction, radiation and / or convection.

The internal component can be arranged on the rig 10. The external component can be arranged outside the rig. For example, the component can be arranged on the ground outside the rig or the component can be arranged on a trailer close to the rig 10. The flushing system is arranged to directly or indirectly heat the at least one component.

[0139] The at least one second nozzle 20 can be configured to produce a mist of atomized liquid. The mist of atomized liquid can be used to cool components 4 on the rig.

[0140] The first flushing medium flows in the flushing channels 3 and optionally in the optional circulation channels 8, 9. The closed loop channel medium flows in the optional closed loop channels 6, 7. The flow can be possible due to the natural flow of the media.

[0141] The cooling or heating effect of the flushing system can decrease during a work shift as the first flushing medium of the flushing medium storage 1 is consumed. This depends on which components need to be cooled or heated and where the components are arranged on the rig in relation to the different channels and possible nozzles. For example, the first flushing medium in the flushing medium storage 1 can be heated during the process if any heat is transferred to the first flushing medium of the flushing medium storage 1. The first flushing medium of the flushing medium storage 1 can also be consumed so that no first flushing medium is left. In the case of using the second flushing medium but no first flushing medium, flushing can continue. However, the cooling or heating of the flushing system can no longer be useful. Heat transfer to and from the first flushing medium of the flushing system can no longer be possible. An enhanced cooling and / or heating effect is obtained by heat transfer through the first flushing medium and the optional closed loop channel medium.
