This article is devoted to the development of mathematical modeling of objects and teaching pedagogical research. Here the emphasis is on the use of case studies of the phenomenological approach. In this regard, a special kind of modeling is released - a phenomenological mathematical and pedagogical. Examples of such modeling, taking into account the possible form of the sequence of events in the learning process. It is noted that a transition from the "hard" mathematical modeling of teaching process in a "gentle".

Today is not uncommon carry out works in open hole drilled oil and gas wells, such as the fight against zones A, test prospective horizons at neftegazosoderzhanie installing a cement bridge and others. Work submersible equipment in the open hole is associated with very severe conditions as a consequence of which pays great attention to the reliability of the equipment and reduce the probability of accidents of work. Packer-anchor complex is the most crucial node in the complexes for the above work in the open hole. To ensure a more reliable and less emergency work in the open borehole must be continuous improvement packer and anchor of the complex on the basis of the development of scientific and theoretically base. The main objectives of the below article is: the development of mathematical models based on the finite element analysis, preparation of loading schemes packer and anchor equipment and their subsequent decision to the definition of places of critical loads in the critical nodes and the complex as a whole, as well as making recommendations for the subsequent strength calculations and develop conceptually new equipment based on the knowledge and relationships.
