Description

Technical Field

[0001] The utility model belongs to the technical field of oil and natural gas mining equipment, in particular to a heating device for oil and natural gas mining. Background Art

[0002] In the middle and late stages of oil field development, the proportion of heavy oil development is increasing. With its abundant reserves, heavy oil will become the focus of the world's crude oil resources. Heavy oil is a high-viscosity, high-density crude oil with poor fluidity and high freezing point. Therefore, it is difficult to extract heavy oil, with low efficiency and high cost. When extracting oil, it is often necessary to heat the wellhead, which can reduce the viscosity of the crude oil: crude oil usually has a high viscosity, making it difficult to flow in underground reservoirs. By heating the wellhead, the temperature of the crude oil can be increased, its viscosity can be reduced, and it can flow out of the underground reservoir more easily.

[0003] In the middle and late stages of gas field development, with the influx of edge and bottom water, the water production of gas wells continues to increase. When the wellhead temperature is low in winter, pipeline freezing is likely to occur, affecting winter natural gas extraction. For gas wells with high water production and prone to freezing, the device can be used for heating to ensure normal gas extraction in low temperature environments in winter.

[0004] The patent document, which is currently named as a heating device for oil and natural gas exploitation, with publication number CN217055074U and publication date July 26, 2022, provides a heating device for oil and natural gas exploitation.

Although the existing heating device for oil and natural gas exploitation can meet normal use needs, it has the problems of slow heating speed and low ventilation efficiency. Utility Model Content
