Abstract

The invention relates to a thermal insulation and heating experimental device of a polar drilling platform derrick. The experimental device comprises an experimental box, a liquid nitrogen circulatingsystem, a derrick model, a derrick thermal insulation wall, a rotating disk, a heater and a data motoring transmission system, wherein nitrogen is injected from one end of the experimental box, and discharged from the other end of the experimental box; the inner center of the experimental box is provided with the derrick model with the thermal insulation wall, and the thermal insulation wall is internally provided with the heater; and the data motoring transmission system comprises a plurality of temperature sensors, data transmission lines and a computer; and can be used for monitoring the temperature data of different positions in the derrick in real time, and transmitting the monitored data to the computer outside through the data transmission lines. The experimental device has the advantages of convenient operation, accurate measurement and high feasibility, and can be used for truly simulating the environment where a polar drilling platform is located, and performing experimentalresearch on the thermal insulation and heating conditions of the polar drilling platform derrick, so that change laws of a temperature field in a thermal insulation layer of the polar drilling platform derrick are obtained.

Description

technical field [0001] The invention belongs to the field of cold protection technology for drilling platforms in polar ice regions, and in particular relates to a thermal insulation and heating experiment device and an experimental method for a derrick of a polar drilling platform. Background technique [0002] As people's demand for oil and natural gas continues to rise, while oil and gas resources in conventional areas are exhausted, countries around the world are currently paying more attention to polar marine oil and gas resources. Polar oceanic regions are rich in oil and gas resources. According to surveys by Russia and other countries, the crude oil and natural gas reserves in the Arctic are about 25% and 41% of the world's proven crude oil and natural gas reserves. With the melting of Arctic glaciers and the advancement of technology, there will be more and more oil and gas drilling activities in polar oceans, and polar offshore equipment has become a research hotsp...
