The present work is devoted to the investigation of soft pp interaction at high energy. Perturbative QCD methods are inapplicable in this kinematics and phenomenological models are being used. The model with the colour strings formation is used at the work. The aim of the present work is to construct the exclusive parton distributions form inclusive structure functions and to develop the methods for generating and applying them for studing of pp interaction features. For this purpose with the special attention the opportunity of modelling the exclusive parton distributions was examined taking into account the energy conservation and holding the centre of mass. Monte-Carlo methods for generating this distributions was developed for arbitrary number of patrons in the hadron. Proton-proton cross sections are estimated with the assumption that the elementary collision is realized as the interaction of two colour dipoles from projectile and target protons. The influence of confinement on that elementary cross sect
