It has been analyzed solution to the problem of definition eccentric location of the drill string in the hole using analytical studies and modern systems of mathematical computer modeling. Practical implementation of technological problem solution was represented as calculated parameters of the formation and changes in the area of stagnant zones in the cross section of the annular space hole in certain baseline characteristics of the process of washing. As a result, studies have found that at lower eccentric placement of both direct and deformed drill string in the well drilling mud flow looks like sickle core flow. The maximum speed of mud while inside the nucleus, and the minimum - in the contact zones flexible pipe and the borehole wall. This change dependencies hydraulic pressure loss pumping mud pump flow rate and distribution of nuclei along the axis of the drill string at its eccentric location in the borehole. It has been determined the conditions of dead mud zones formation in the annular space and offered solutions to solve this problem.
