It is recommended to use chlorine-potassium, chlorine-calcium washing fluids, reagents KMC, KSSB and potassium and sodium chromates. The new method of determination of content change and fraction C5+ recovery during gas-condensate pools development is proposed, which is based on the hydrocarbons C5+ balance only in the residual formation gas. In the presence in the gas-condensate systems dispersed liquid hydrocarbons of petroleum series it is recommended carrying out investigations on the installations of phase equilibrium without release of unsoluble residue. The estimation of industrial exploitation expedience of new fields - Musiyenky gas-condensate and West-Yefremivka gas fields (DDD), was accomplished. Both fields are recommended for industrial exploitation. The peculiarities of capillary microprocesses (wettability of the surface, capillary pressure) in the rocks-reservoirs by means of devised methods are studied. It is established that over the range of saturation 60-90 % the capillary forces do not influence on hydrocarbons recovery effectiveness; methodical questions of residual water saturation determination with due regard of interstitial water anomalous properties (density) by centrifuging and capillary suction (extract) methods are examined; experimentally on the glass capillaries the influence of sinuosity on liquids and gas filtration is studied; the designes of core holders for linear and radial filtration of liquids and gases on large-scall cores are worked out; the boundary and standard values of filtration-capacitive reservoirs characteristics of the DDD Andriyashivka, Svyrydivka, Lutsenky, Mekhedivka, Chervonozavodske, Rudivka fields are substantiated.
