Abstract

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 possible, increase the cohesion forces in the rocks. In order to maintain the stability of the wellbore, to prevent outbursts of formation fluids and losses, the mud must have, first of all, 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 density of the drilling fluid 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. Shown are the basic applied, physicochemical and rheological properties of drilling fluids. The results obtained can be used in the production of stabilizing reagents, which can be used as components for rapidly dispersing drilling fluid concentrates in water, as well as for other compositions with other end uses. The development provides for the production of stable aqueous suspensions, 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 production of drilling fluids. Dry powder redispersible drilling fluid concentrates reduce the cost of transporting materials.
