The wave technologies of influence on multiphase systems can find application for an intensification of hydrocarbon production technological processes, including increase gas and condensate recovery. By means of cyclic wave influences, it is possible to change hydrodynamic and thermodynamic properties of mass transfer process in a gas-condensate stratum and promote increase in an output of gas and condensate. A series of experimental and theoretical works on modeling of mass transfer processes in two phase system (a mixture methane-n-butane) at conditions (pressure and temperature) of real gas-condensate stratums is carried out. Numerical model of a two-phase filtration of hydrocarbon mixtures in a porous medium for modeling of acoustic waves influence is developed. Similarity parameters of process are received, resonance frequencies and the amplitudes of the wave influence providing minimal time of a condensate plug destruction are found.

Experimental facility allowing to investigate thermo physical properties of hydrocarbon fluids, as well as to model filtration processes of a oil and gas-condensate mixtures in one-dimensional physical model of a layer at pressure up to 40 MPa and temperature up to 400 degrees of Celsius is created. Determination of viscosity and surface tension of fluids by the analysis of nonlinear oscillations of a viscous liquid drop using developed mathematical and numerical methods is made. Results of experimental investigations of thermophysical properties of hydrocarbon fluids, and results of thermal influences on gas-condensate mixture are presented.
