| Abstract: | CCI in natural oil-saturated core samples has been experimentally investigated. The oil displacement coefficient is determined by comparing the initial and final oil saturations of the sample. The effect of temperature and time on the intensity and rate of CCI is explored. The results of the investigation are scaled up to correspond to the conditions of a real oil deposit on the basis of a well-known similarity criterion. It is shown that the rate of CCI falls significantly with increase in the size of the blocks. In order to intensify CCI it is necessary to heat most of the reservoir with a high-temperature heat transfer agent.Translated from Izvestiya Akademii Nauk SSSR, Mekhanika Zhidkosti i Gaza, No. 3, pp. 62–67, May–June, 1990. |
