Effectiveness of wave processes in tubing strings, wells and long pipelines may be limited by damping of hydrodynamic waves along the length of the channel. Violation of thermodynamic equilibrium in reservoir fluids during their rise to the surface and in ground pipelines may be accompanied by the release of asphalt-resin-paraffin components in the flow of crystals due to a decrease in temperature and pressure. Subsequent depositing of crystals takes place as they grow, due to adhesion to the wall of pipes, the surface of equipment. Deposits are most intensified in areas of local expansion and narrowing of the cross-section area of the flow (occurrence of vortices).
