 Abstract
The paper presents an analysis of the evolution of drill bits and PDF drill bits. With the increase of drilling depths of the wells, new excavations have been imposed, which should resist the elevated degree of hardness of the well holes, the elevated temperatures and the pressures that may occur during the drilling process. PDC drill bits have demonstrated that they can successfully deal with these conditions.


 Rezumat
Lucrarea prezinta o analiză a evoluției sapelor cu role și a sapelor PDC. Cu creșterea adâncimii de forare a sondelor s-au impus noi construcții de sape, care să reziste la duritățile mari din găurile de sondă, la temperaturile crescute și la presiunile ce pot apărea în timpul forajului. Sapele PDC au demonstrat că pot face față cu succes acestor condiții.
