Description

Technical Field

[0001] The invention relates to the technical field of temperature measurement, and in particular to a multi-energy heating temperature measurement device for heating crude oil in oil fields. Background Art

[0002] The crude oil extracted from the oil well generally needs to be transported through long pipelines and then distributed to specific application locations. However, since crude oil has disadvantages such as high freezing point, high viscosity and poor fluidity at room temperature, the crude oil pipeline needs to be heated during the crude oil transportation process to reduce the viscosity of the crude oil and improve the pipeline transportation capacity and efficiency.

[0003] As a widely used clean and renewable energy, solar energy has the advantages of being universal, harmless, having large reserves and long-term use. Therefore, solar collectors are selected as the main heat source of the system. This system design not only reduces energy consumption, but also greatly reduces pollution to the atmospheric environment. Currently, there are two commonly used solar collectors: flat plate collectors and vacuum tube collectors. Compared with vacuum tube collectors, flat plate collectors have the advantages of simple structure, reliable operation, suitable cost, strong pressure bearing capacity and large heat collection area.

[0004] When crude oil is heated or stored in a container, the temperature of crude oil at different depths varies because the container is usually large. Although some companies use multiple fiber optic sensors to detect the temperature of crude oil at different depths in the container, the temperature collection area is still relatively limited, and the temperature measurement data is not accurate enough.
