Abstract

The invention relates to a polar drilling platform derrick heat preservation and heating experiment device, comprising: an experiment box, a liquid nitrogen circulation system, a derrick model, a derrick insulation wall, a turntable, a heater, and a data monitoring and transmission system; wherein: one end of the experiment box injects nitrogen, and the other Nitrogen gas is discharged from one end; a derrick model with an insulation wall is set in the center of the experiment box, and a heater is installed in the insulation wall. The data monitoring and transmission system includes multiple temperature sensors, data transmission lines and computers, which can monitor the temperature data at different positions inside the derrick in real time. And the monitored data is transmitted to the external computer through the data transmission line. The experimental device of the present invention is easy to operate, accurate in measurement and high in feasibility, can truly simulate the environment of the polar drilling platform, and conduct experimental research on the thermal insulation and heating of the polar drilling platform derrick, thereby obtaining the temperature inside the polar drilling platform derrick insulation layer field changes.

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...
