Özet

In this study, the salt production boreholes drilled by the Institute of Mineral Research and Exploration (MTA) for the Mersin Soda Industry in the Adana-Karakuyu-Arabali region were evaluated. The technical characteristics of the drilling equipment and cone (rock) bits used in the boreholes are explained. Caliche, claystone with siltstone, salt and anhydrite interbedding formations of the Pliocene-Messinian Age were drilled. Bentonite and natural water were used as the drilling mud. The density and viscosity properties of the drilling mud were measured continuously. The revolutions per minute (RPM) and weight on bit (WOB) were kept constant or within particular interval limits during drilling. This was due to the fact that the geological and mechanical characteristics of the drilled formations did not vary significantly. Although the salt reserve was not determined exactly, the underground salt thickness map suggests that there may be a huge reserve of salt. The salt was saturated with water and was pumped to the Mersin Soda Industry.
