Principles of calculation of drilling parameters with simultaneous freezing of passable rocks
Abstract
The purpose of simultaneous with the drilling process of freezing of passed melted rocks is to ensure their monolithicity and strength, which makes it possible to avoid complications associated with the instability of loose wet rocks, and to obtain a high core yield.
