Key words: PDC bits, wells, well profile, design the cut, designing wells, homogeneous bundle, suite, shuttle speed, the structure of the geological and technical information, algorithm type selection bit, zenith angle.
In the course of well the actual problem is the choice of the type of PDC bits from a database of drilled wells. The selection criterion is defined as the maximum shuttle speed of the finished chiselling. For the latest dolblenii under the intermediate, operational and shank casing is adopted the criterion of choosing the type bits for the minimum value of the residuals in the caverns between the applicable bits from the database and the size of the design profile along the trunk to the depth of the last proektnogo chipping. The solution to the problem of selecting the last bits allows the use of do not end up worn drill bits from a database of drilled wells and reduce the cost of the well.
