The variants of solving the problems of two-phase flow measurement by means of representative sampling and its subsequent analysis at the installations (devices), simpler in design than the "full-length" DF meter are considered. The techniques applied for solving the problem of determination of the proportion of the liquid phase volume in the products produced from wells of gas-condensate and oil-gas-condensate fields under operating conditions are discussed in detail; the solution of the problem relating to components costs reduction from working conditions to standard or normal ones is proposed. In all the cases the analyzer is based on the open cylindrical resonant cavities operating at millimeter waves range. The problem of a representative sample selection is analyzed; the technique of density profile determination with the help of flow multimode sensing by oversize resonators, excited at different types of vibrations is considered. It is assumed that the methods of analysis based on a representative sample selection can be applied to solve the problem of the two-phase flow measurement.
Key words: representative sample; liquid volume ratio; isokinetic sampling probe; anti-aerosol filter; millimeter waves; open cylindrical resonant cavity; multimode sensing; flow density profile; working conditions; bringing to normal conditions.

Free gas breakthrough when operating oil-gas-condensate fields complicates oil production and makes it difficult to control production characteristics of wells. The paper presents an algorithm of indirect (computational) determination of production of oil, condensate, free and petroleum gas using information about liquid hydrocarbons production and gas in wells, as well as PVT-properties of the produced reservoir fluids. A preliminary prediction of gas breakthrough from gas caps of oil-gas-condensate reservoirs into the wells of Pyakyakhinsky field using this algorithm is done. It resulted in revealing of a high risk degree of gas breakthrough for the objects with a big amount of contact reserves and wells with horizontal tailing.
Key words: oil-gas-condensate fields; free gas breakthrough; algorithm of indirect (computational) determination of hydrocarbons production.
