The article discusses some issues of creating new affordable and cheap stabilizer-reagents for drilling fluids based on local and secondary resources. It has been established that in the process of drilling, in order to prevent rock falls, the mud should not decrease, but, if it’s possible, increase the cohesion forces in the rocks. In order to maintain the stability of the wellbore, to prevent outbursts of fluid and loss formation, primarily, mud is to have the required density. Stabilizing reagents are primarily designed to reduce filtration and viscosity of the drilling fluid. It has been established that in each specific case the optimal value of the drilling fluid density should be selected. It has been experimentally revealed that the drilling fluid containing the new stabilizer has a high lubricity. By lubricating the surface of pipes, bit bearings, hydraulic equipment, the solution helps to reduce energy costs for drilling. All above is the basic applied, physicochemical and rheological properties of drilling fluids. The results obtained can be used in the stabilizing reagent production, which can be used as components for rapidly dispersing drilling fluid concentrated in water, as well as for other compositions with other end uses. The development provides with the of stable aqueous suspension production, characterized by optimal rheological properties and allowing to obtain such rapidly dispersing in water concentrates of drilling fluids. This results in a number of practical advantages, including the ability to produce and store a dry product - a powdered drilling fluid concentrate that can later be easily redispersed in the drilling fluid production. Dry powder redispersible drilling fluid concentrates reduce the cost of transporting materials.
