Investigation of the temperature regime of frozen rock cores
Authors:
Abstract
In the process of drilling, heat is generated in the bottom-hole zone due to mechanical work of the rock-destroying tool. As a result, the natural temperature and phase state of frozen rock cores is disturbed. Studying the mechanism of frozen rock core thawing during drilling, elucidating the regularities of the thawing process for deliberate regulation and normalization of its temperature regime are of practical importance.
