Timely elimination and prevention of accidents and complications during drilling operations are among the main factors that help reduce the time spent exploring and prospecting a field and the operation of technological and technical wells. In the process of drilling wells, preventing downtime associated with the absorption of drilling mud allows reducing the cost and timing of drilling operations, which in turn leads to an increase in the productivity and efficiency of drilling operations. In this article, a mathematical model has been developed that allows calculating the volume of the cavity, taking into account the geometric parameters of the pores and cracks in the walls of the sound design of a drilling tool has been developed that allows covering individual sections of the well with a casing pipe, absorbing the washing solution. The results of an experimental study of the developed drilling tool are presented.
