| Abstract: | Injection of water vapor is an effective method of thermal action on oil-bearing seams in order to intensify the oil output and increase its yield 1]. In determining the technological characteristics of this process, it is necessary to know the dimensions of the vapor and hot liquid zones created in the seam, and also the distribution in the seam of the degree of vapor dryness. There are already well-known studies of the determination of vapor and hot liquid zones 2, 3], but the distribution of the degree of vapor dryness has not been considered. In the present study a method similar to the known method of successive interchange of steady states 4] is used in order to obtain an equation for the calculation of the distribution of the degree of vapor dryness when the vapor is injected with unchanged flow rate into a homogeneous seam. As a consequence, equations have also been obtained for the calculation of the vapor and hot liquid zones.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 1, pp. 174–176, January–February, 1986. |
