摘要：In article it is shown the functional connection between the drillability model and the required consumption of drilling mud for cleaning the bottom of a well from destruction products. In particular, it has been shown that when drilling oil-gas wells in uncomplicated conditions, the required consumption of drilling mud is directly proportional to the current drilling speed and increases in quadratic dependence on the diameter of the well. It was found that the increase in the density of drilling mud due to contamination with drill cuttings at the revelation of "weak" formations has the greatest influence, which in certain conditions can cause hydraulic fracturing of the formation. At the revelation of formations with abnormally high pressure, an increase in the density of the contaminated drilling mud has practically not influence on the prevention of kicks.
