Annotation:

Solving the problem of looking for the most acceptable values of drilling parameters, focused on high rates of penetration and maximum operational life-time of the drilling tool, allows optimizing drilling costs. In this case, the research efficient way is the search for functional relationships between various criteria. In addition to optimization of the drilling regime parameters in order to increase wells drilling efficiency, the choice of the functional structure of the drilling rig, the use of which makes it possible to reduce financial and production costs for wells construction, is very significant. The article presents the results of the practical application of the concept of improving the efficiency of drilling wells in the fields of the Nizhnevolzhsky region, based on the study of the process using the mathematical apparatus of the theory of similarity and determination of the boundaries of drilling rigs effective use.
