... drilling perforations channel with small radius of curvature from 3.5 to 12 meters, controlling their length and trajectory up to 14 meters (on the first stage of the project). Сonclusions 1. Analytically proved that using flexible connections in the composition perfodrill BHA allows to obtain perforation path with minimum curvature radius similar to a circular arc which fits into the layout. 2. The analytic dependence between geometric parameters of compact layout of the technical system «Perfodrill» ...
