Abstract
Abstract Environmental pollution in the areas of drilling and field development is one of the main priority environmental problems. At the same time, as observations show, the main objects of pollution are groundwater, hydro-and lithosphere (open water bodies, the bottom of water areas, soil and vegetation cover). Sources of pollution are the results of the process itself. The greatest danger posed to environmental objects is technological drilling waste, which is accumulated and stored directly on the drilling site. Drilling waste includes drilling cuttings, waste drilling fluids and drilling wastewater. They are formed in the process of washing the well. In the process of deepening a well at the bottomhole, a drill is formed. Hydrotransport that drills mud from the bottom of the well to the surface of the rock under the influence of man-made factors turns into drill cuttings. Therefore, in the cleaning system of the circulating system of a drilling rig, the cuttings are not separated from the drilling fluid. But drill cuttings differ in volume and, most important from an environmental point of view, in physicochemical properties. The volume of cuttings is equal to the volume of the wellbore. When designing, the volume of drill cuttings is approximately taken by 20% more than the volume of cuttings.
