Abstract

A model problem for the gas extraction process from UGS while substituting it with water is developed. The connection between the mass flowrate and pressure values in the main gas pipeline and on the outer water surface is established. A mathematic model for calculation of the UGS functioning parameters during the period of gas extraction is constructed. The results obtained are tested on the model problem. Розроблено модельну задачу процесу вiдбирання газу з ПСГ витiсненням його водою. Побудовано зв’язок мiж дебiтом свердловини та значеннями тискiв у магiстральному газопроводi та на зовнiшнiй межi води. Наведено формули розрахунку параметрiв роботи ПСГ пiд час вiдбирання газу. Отриманi результати апробовано на модельнiй задачi.
