Accounting for the temperature conditions during deep prospecting hole drilling

Journal Article:

Abstract

A methodology is described for calculating and controlling the temperature in inclined holes in order to establish a non-steady-state heat exchange between the medium circulating in the hole, and the construction components and rock. In order to verify the proposed methodology, the temperature of the drilling fluid is measured directly during the drilling process using a specially-designed automatic device which is lowered into the hole with the drilling string and turned on automatically at a given depth. This device makes it possible to record the drilling fluid temperature on magnetic tape, and convert the sensor signals arriving from the drilling string and the annular space. A comparison of calculation and experimental data confirmed the sufficiently high accuracy of the methods for predicting the thermal conditions in drilling deep prospecting holes.
