In dieser Monographie wird die Verwendung von Bentoniten und Palygorskiten aus verschiedenen Lagerstätten bei der Herstellung von Bohrschlämmen aufgrund der unterschiedlichen Zusammensetzung und Eigenschaften der verwendeten Rohstoffe recht unterschiedlich dargestellt. Um ihre Eignung für die Herstellung von polyfunktionalen Bohrschlämmen zu bestimmen, sind spezielle Untersuchungen ihrer mineralogischen und chemischen Zusammensetzung sowie ihrer physikalischen und chemischen Eigenschaften erforderlich. In Usbekistan gibt es beträchtliche Reserven an Bentonit, Palygorskit und wasserhaltigen Tonen, die nicht als Rohstoffe verwendet werden, weil ihre Zusammensetzung und ihre physikalischen und chemischen Eigenschaften nicht ausreichend untersucht wurden und es an wissenschaftlich fundierten Technologien und Rezepturen für die Herstellung von hitze- und salzbeständigen Bohrspülungen fehlt. Unter diesem Gesichtspunkt wird die theoretische Begründung und experimentelle Untersuchung der Anwendung einiger Bentonite, Palygorskite der Navbahorsk-Lagerstätten und wasserhaltiger Tone der Shorsuva-Lagerstätten als Grundlage für die Gewinnung wärme- und salzbeständiger Bohrschlämme sowie die Entwicklung der Methode der Anwendung mechano-chemischer Dispergiermittel zur Gewinnung wärme- und salzbeständiger Bohrschlämme aus polymineralischen Zusammensetzungen als eine ganz aktuelle Aufgabe angesehen.
