Abstract
It is necessary to know the value of the gas factor in order to perform technological calculations when designing systems for the rational use of associated petroleum gas. The value of the gas factor is determined by the results of a study of deep oil samples. As a rule, the well production of oil fields is waterlogged, and its value increases with time. Many researchers have proven the fact of the dissolution of hydrocarbon gases in reservoir water; for example, according to some results, up to one cubic meter of gas can be dissolved in one cubic meter of water. This fact has a significant impact on the technological modes of operation of well production preparation units, since in their design only the value of the gas factor of the produced oil is taken into account. It is necessary to develop a reliable method for calculating the limiting gas content of reservoir water and the amount of gas releasing during pressure reduction in order to correctly account for the volume of gas dissolving in produced water. The article presents the results of studies on the calculation of the gas factor of reservoir water using various methods; the obtained results are compared with laboratory data.
