[0002] The heating system currently used on low-temperature mobile drilling rigs is a steam boiler heating system, which is equipped with an independent boiler room, fuel tank and water tank. The diesel, crude oil or other fuel delivered is fully burned through the burner installed on the boiler, and then the steam generated by the boiler is transported to the parts that need to be insulated through pipelines, including the mud pump area, mud tank area, storage tank area, drill floor stand area, personnel operation area (including driller's room, driller's side room, gas source room, etc.) and other areas where equipment needs to be heated.

[0003] However, the steam boiler heating system requires a separate water source for the boiler during actual use, and the water transported to the boiler must also be softened. If the treatment does not meet the requirements, it will damage the boiler. Due to the relatively harsh conditions at the well site, the supply of water is difficult to guarantee; and the water generated after the steam circulation is difficult to collect. Since the steam circulates to different areas of the drilling rig, it cannot be collected in a centralized and unified manner. Several collection devices must be set up. If the collected water is not handled properly, it is easy to freeze at low temperatures, causing equipment damage.

[0004] Therefore, it is necessary to provide a heating system for a low-temperature drilling rig to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0025] First embodiment

[0026] Please refer to Figure 1 ,in, Figure 1 This is a schematic structural diagram of a first embodiment of a heating system for a low-temperature drilling rig provided by the present invention. A heating system for a low-temperature drilling rig comprises: a fuel tank 1;

[0027] A heated oil suction pipe 2, the heated oil suction pipe 2 being fixedly mounted inside the top of the fuel tank 1, a first oil pipe heating joint 3 being fixedly mounted on the output end of the heated oil suction pipe 2, a heated filter assembly 4 being fixedly mounted on the output end of the first oil pipe heating joint 3, a temperature sensor 5 being fixedly mounted on the output end of the heated filter assembly 4, and a second oil pipe heating joint 6 being fixedly mounted on the output end of the temperature sensor 5;

[0028] A fuel heater 7, wherein the input end of the fuel heater 7 is fixedly mounted to the output end of the second oil pipe heating joint 6, the output end of the fuel heater 7 is fixedly mounted to a hydraulic oil tank heater 8, the output end of the hydraulic oil tank heater 8 is fixedly mounted to an engine water tank 10, and the output end of the engine water tank 10 is fixedly mounted to the input end of the fuel heater 7;

[0029] The diesel engine 11 is fixedly mounted on the output end of the second oil pipe heating joint 6 , and an operating room 12 and a battery box 13 are fixedly mounted on the output end of the diesel engine 11 .

[0030] A hydraulic oil tank 9 is provided on the outer side of the hydraulic oil tank heater 8 .

[0031] The diesel engine 11 is disposed on one side of the engine water tank 10 .

[0032] The coolant in the engine water tank 10 is extracted and heated by the water pump of the fuel heater 7, and then circulated to the engine water tank 10 to heat the diesel engine 11, thereby achieving the purpose of starting the diesel engine 11 under low temperature conditions;

[0033] After the hydraulic oil in the hydraulic oil tank 9 is heated by the hydraulic oil tank heater 8, the temperature of the hydraulic oil rises to a temperature at which the drilling rig can operate normally, effectively solving the problem that the hydraulic system cannot operate normally in a low temperature environment;

[0034] The second oil pipe heating joint 6 is connected to the oil inlet end of the diesel engine 11 and the oil inlet end of the fuel heater 7 respectively;

[0035] The first oil pipe heating joint 3 and the second oil pipe heating joint 6 adopt electric heating to convert electrical energy into thermal energy, thereby increasing the surface temperature of the joints and achieving the purpose of heating, which can heat the oil supply pipeline;

[0036] Cold air and diesel enter the combustion chamber of the diesel engine 11 through different pipes, are ignited and burned by the spark plug, and are then discharged as hot air after heat exchange in the heat exchanger to achieve the heating effect;

[0037] The heat generated by the diesel engine 11 burning diesel generates hot air through the heat exchanger and is sent into the battery box 13 to heat the batteries.

[0038] The working principle of the heating system of a low-temperature drilling rig provided by the utility model is as follows:

[0039] During use, the fuel in the fuel tank 1 is drawn out through the heated oil suction pipe 2, heated through the first oil pipe heating joint 3, and then transported through the oil pipe to the inside of the heating filter 4, where the fuel is heated again. The fuel is then transported through the temperature sensor 5 and the second oil pipe heating joint 6 to the inside of the diesel engine 11 and the fuel heater 7, respectively.

[0040] Then, the fuel heater 7 is started, so that the water pump inside the fuel heater 7 draws out the coolant inside the engine water tank 10 to heat it, and then transports it to the inside of the hydraulic oil heater 8 through the pipeline, so that the hydraulic oil heater 8 heats the hydraulic oil inside the hydraulic oil tank 9, and then transports it to the inside of the engine water tank 10 through the pipeline, thereby circulating;

[0041] The engine water tank 10 heats the diesel engine 11, which is then started. Cold air is drawn in for heating, and then heat is exchanged through the heat exchanger. The hot air is transported through pipes to the inside of the operating room 12 and the battery box 13, respectively, to heat the batteries inside the operating room 12 and the battery box 13.

[0042] Compared with the related art, the heating system of a low-temperature drilling rig provided by the present invention has the following advantages:

[0043] Beneficial effects:

[0044] The heated oil suction pipe 2 and heated filter 4 work together to draw fuel from the fuel tank 1, heat it, and then deliver it to the diesel engine 11 and fuel heater 7. The fuel heater 7 heats the coolant in the engine water tank 10 and the hydraulic oil in the hydraulic oil tank 9, starting the diesel engine 11 and providing heat energy for the operator's cabin 12 and battery box 13. This eliminates the cumbersome steps of separately supplying and softening water to the steam boiler heating system, overcomes the challenge of unreliable water supply in the harsh wellsite environment, and reduces the risk of equipment failures caused by water problems.

[0050] The engaging slot 43 is formed on the top of the top cover 42 , and the connecting frame 46 is engaged with the inner side surface of the engaging slot 43 .

[0051] The working principle of the heating system of a low-temperature drilling rig provided by the utility model is as follows:

[0052] When maintenance of the interior of the main body 41 is required, the user can rotate the rotating plate 48 so that the rotating plate 48 drives the threaded ring 47 to be threadedly connected to the outer side of the main body 41, and then the threaded ring 47 drives the rotating ring 44 to move upward, so that the rotating ring 44 drives the connecting frame 46 to move upward through the rotating shaft 45, so that the connecting frame 46 moves out from the inner side of the clamping groove 43, and then rotate the connecting frame 46 to move the connecting frame 46 away from the top of the top cover 42. At this time, the user can remove the top cover 42 from the top of the main body 41 and then maintain the interior of the main body 41.

[0054] Beneficial effects:

[0055] By threading the threaded ring 47 on the outer side of the body 41, the connecting frame 46 is driven upward by the rotating ring 44 to move the connecting frame 46 out of the inner side of the clamping groove 43. The connecting frame 46 is then rotated to move the connecting frame 46 away from the top of the clamping groove 43, and the top cover 42 can be removed from the top of the body 41, thereby facilitating the user to quickly open the fuel filter protective shell and clean the interior.
