Title:
DEEP-ULTRA-DEEP ROCK MECHANICS PARAMETER PREDICTION METHOD IN CONSIDERATION OF TEMPERATURE EFFECTS
Document Type and Number:
WIPO Patent Application WO/2021/232924
Kind Code:
A1
Abstract:
A deep-ultra-deep rock mechanics parameter prediction method in consideration of temperature effects, which is suitable for the fields of geology and rock mechanics in oil and gas development. A core taken from a deep-ultra-deep layer has actually subjected to the processes of slow heating and rapid cooling, and in order to eliminate an influence thereof on a rock mechanics property, deep-ultra-deep rock mechanics parameters are predicted by establishing a correlation between rock mechanics parameters before and after a temperature difference loading path. The present invention has simple steps, good effects, and high reliability of a measurement result.
