The use of clay from the Herpegezh deposit for the production of ready-made compositions for the preparation of drilling fluids

The preparation of drilling fluids from ready-made compositions allows you to reduce costs, including by obtaining the drilling mud of the required composition with an optimal consumption of reagents, simplifying technological equipment and reducing requirements for the qualification of maintenance personnel. One of the most common components of drilling fluids are clays, therefore, one of the important tasks is to study clays from various deposits in order to establish the possibility of their use in the production of compositions for the preparation of drilling fluids. The purpose of this study was to establish the chemical and technological characteristics of the clays of the Herpegezh deposit and to develop recommendations for the preparation of finished compositions. Particular attention was paid to the choice of the method of activation of raw materials, ensuring the maximum possible productivity, in particular, the traditional method of activation and mechanical activation in the disintegrator were compared. Also, as a result of the conducted experiments and processing of their results, the dependences of the technological characteristics of the drilling mud prepared from the Herpegezh clays on the mass fraction of the clay substance were established.
