Study of the Injection Process of "Dry" Hydrocarbon Gas at Different Stages of Gas-Condensate Fields Development

In the presented study was investigated the effectiveness of the injection process of "dry" hydrocarbon gases to the bottom-hole zone, depending on the different stages of gas condensate fields development. The experiments were carried out in a special sequence of PVT bombs, to eliminate the impact of specific factors caused by the concrete development conditions of different fields. For this purpose, five series of experiments were performed, and some experiments were repeated several times to confirm the results. Obtained results were not only helpful in assessing the injection process, but also for selecting an effective injection option. Thus, for the first time, the process of "dry" gases injection to the bottom-hole zone has been experimentally investigated at all stages of gas condensate fields development, and effectiveness of the process has been determined at the first stage of field development. It has also been established that maximum condensate production can be achieved even with lower pressure by controlling the condensate volume of the layer system and single phase.
