Abstract

The probable reasons of stratal water found in the hydrocarbon reserves and in the wells are considered in this article. It is established that areas of reservoirs with the hydrophobic character of wettability complicate the process of hydrocarbon reservoirs development because of their selective flooding. The mechanism of selective flooding action is shown. It is proved that the reservoir rocks of gas-condensate reservoirs with a high content of condensate in the formation gas are water-repelling in the development process. In the paper a methodological approach is suggested, based on which it is possible to predict the most likely direction of stratal water flow for irrigation mechanism of the selective flooding, which will make it possible to adjust the process of hydrocarbon reservoirs development. To do this, it is important to have specific geological and hydrodynamic models.
