A composite heating and heat preservation system for drilling rigs

Abstract

The invention discloses a composite heat supply and heat preservation system for drilling rigs, which comprises a first-stage hot-air pressure-stabilizing tank, a sand-proof tank shed, a first hot-air booster fan, a second hot-air booster fan, and a second-stage hot-air pressure stabilizer Tank, generator waste heat heat exchange mechanism, control valve group, drilling platform, electric heating boiler and engine heat exchange mechanism, while the sand prevention tank shed includes high-pressure mud pump unit, third mud tank group and fourth mud tank group. The invention provides a composite heating and heat preservation system for drilling rigs, which can realize comprehensive and effective three-dimensional space antifreeze and thawing, has good heat preservation effect, high heat transfer efficiency, can reduce the failure rate of equipment operation, and has a high safety factor. It requires less inspection and maintenance costs, less coal consumption and water consumption, and can reduce air pollution and underground pollution.

Description

technical field [0001] The invention relates to the field of oil drilling rigs, in particular to a composite heating and heat preservation system for drilling rigs. Background technique [0002] At present, oil drilling rigs use steam boilers (coal, oil, gas) for heating in winter, and traditional coal-fired steam boilers occupy an absolute leading position in heating and insulation. The steam produced by the traditional coal-fired steam boiler is used as the heat transfer medium to be pressurized by the circulating booster pump and connected in series to each equipment or related heat exchange device that needs to be heated and kept warm, and is connected with the liquid in the related equipment or heat exchange device. Or air for heat exchange, so as to complete the purpose of thawing and heat preservation. Although the existing heating and antifreeze insulation methods can achieve the purpose of thawing and insulation to a certain extent, there are still defects and safe...

Problems solved by technology

[0010] The technical problem to be solved by the present invention is that, in view of the problems in the prior art that the heating and heat preservation system of the drilling rig can only realize partial antifreezing and thawing of the drilling equipment, the heat preservation effect is poor, the heat transfer efficiency is low, the failure rate is high, the safety factor is low, the inspection and The maintenance cost is relatively large, the coal consumption is large, the water consumption is large, and it is easy to cause air pollution and underground pollution. Provide a comprehensive and effective three-dimensional space antifreeze and thaw, good heat preservation effect, high heat transfer efficiency, A drilling rig composite heating and heat preservation system that can reduce the failure rate of equipment operation, has a high safety factor, requires less inspection and maintenance costs, consumes less coal and water, and can reduce air pollution and underground pollution
