Hydrothermal coupling model between wellbore and permafrost …
3 天之前 · Vacuum insulated tubing (VIT) and drilling fluid cooling systems are the most widely used wellbore temperature control technologies in cold regions drilling. Although these two technologies are already mature, research on these wellbore and formation temperature-controlling technologies from the perspective of the entire drilling process is ...

comprehensive review of the cold regions of the Northern Hemisphere. Northward expansion of the civil economy and military activities has created a need for readily available information on the climatology, physical characteristics and properties of the concomitant materials of the cold regions of the earth.
Hydrothermal Coupling Model between Wellbore and Permafrost …
2024年8月9日 · Therefore, this paper proposes a hydrothermal coupling model between the wellbore and formation for drilling in Arctic cold regions and analyzes the heat transfer in the wellbore and the hydrothermal processes of the formation using numerical methods.
Well drilling in permafrost regions: dynamics of the thawed …
In the cold regions, warm mud is usually used to drill deep wells. This mud causes formation thawing around wells, and as a rule is an uncertain parameter. For frozen soils, ice serves as a cementing material, so the strength of frozen soils is significantly reduced at …
Influence of drilling fluid temperature on borehole shrinkage …
Borehole shrinkage occurs due to the plasticity and creep of frozen soil that ensues during drilling operations in cold regions. Based on the change of mechanical properties of frozen soil during the heat transfer process that occurs between the drilling fluid and the formation, a heat-fluid-solid coupling model is established in this paper to ...
