Two mathematical models are suggested, which describe process of a crystallization of oil paraffine in gas-oil well. In the first scheme it is necessary that the formation of a solid phase is basically determined by losses of fluctuation of a fluid near the walls because of its hardening with temperature fall. The second scheme allows for the diffusion gear of transposition of heavy hydrocarbonaceous components in a fluid to a surface of a solid phase. The generalizing of a case of dependence of intensity of formation of paraffines on intensity of association of fragments in a rigid surface is concluded. The numerical study of influencing of the different factors on intensity of paraffine depositions of production string of well is held.
