Development of technical solutions to ensure the supply and measurement of the unstable gas condensate from Valanzhinsky deposits of the Big Urengoy fields during production decline
The paper presents the results of the technical solutions implementation providing, in conditions of the reservoir pressure significant drop, the planned indicators of hydrocarbon production, maintenance of regulatory modes of the low-temperature separation process, compliance with all requirements for the well products supply to the inter-field reservoir. The description of technical solutions proposed by the specialists of LLC "Gazprom dobycha Urengoy" is given. The commissioned condensate pumping station, which implements the principles of poorly populated technologies, is considered, particularly, an automated technological complex for accounting of unstable gas condensate is used. The developed and implemented technical solutions are aimed at ensuring qualitative and quantitative characteristics of unstable gas condensate; they also eliminate the discrepancy in the amount of the supplied products between LLC "Gazprom dobycha Urengoy" and LLC "Gazprom pererabotka".
