INVESTIGATION OF RHEOLOGICAL PARAMETERS OF BENTONITES IN DRILLING FLUIDS

Abstract

Use of natural bentonite in drilling industry is one of the important ways to enhance the quality of the well construction and technology. Inhibiting the ability of drilling fluids on the basis of a bentonite dehydrates and strengthens the wellbore, which eliminates the landslides and talus rock. Drilling muds based on natural bentonites have specific properties and, in particular, have a flocculation effect on slurry of drill cuttings. Proposed drilling muds biodegradable and do not require additional measures for disposal.
