Experimental modeling of oil and gas condensate type fields development processes

J.N. Tahirov

The oil and gas condensate fields represent the most difficult type of natural hydrocarbon deposits, not only by condition, composition and fluids bedding conditions in them, their behavior in the further development process, but also from the technological point of view. Such kind of field development becomes complicated from one side due to the possible gas-hydrodynamic influence among oil and gas deposits with their hard-controlled contact displacements and intensive phase transition with further change of composition, physical properties and saturation. From the other side it is resulted from field facilities construction with complicated well production collection, distribution and utilization systems, working effectively in high pressures. Here are looked through the features of oil and gas, gas-condensate fields development. In the article are shown the statement and results of the experiment in which the process mechanisms occurring in the oil and gas condensate deposits development various variants were studied. The description of experimental installation is given. As it was noted, the filtration process modeling was carried out via chemically pure gases and liquids. For studying of real gases and liquid interaction were conducted investigations on formation fluid thermodynamic properties of Guneshli offshore oil and gas condensate field. The works were carried out on pVT installation UiPn-AzNiPineft, calculated on 100 МPа working pressure and temperature in 200 oС. Apparently from the installation name the research works are carried out in a high pressure vessel (i.e. pVT bomb) without participation of the porous medium.
