| dc.description.abstract | A horizontally layered elastic structure containing a homogeneous porous layer saturated partly with gas and partly with water is considered. The paper is aimed at studying of interaction of elastic waves, caused by local pulse source, with the structure. The boundary-value problem describing the wave dynamics of the structure is formulated. A mathematical model describing distributions of the gas and water in a pore space of the porous layer depending of the amount of the gas accumulated in the layer is developed. The problem is solved with the use of Fourier transform. It was established that wavefield pattern on the free surface of the structure is dependent on amount of gas accumulated in the porous layer. Quantitative measures relating the wavefield parameters on the structure’s free surface and the amount of gas accumulated in the porous layer are introduced. The obtained results can be used to develop distance methods for accounting of amount of natural gas accumulated in underground gas storage facilities built in aquifers. Дослiджено взаємодiю пружних хвиль, зумовлених локальним iмпульсним джерелом, iз пiвбезмежною горизонтально-шаруватою структурою, що мiстить пористий шар, насичений газом i водою. Запропоновано математичну модель, яка описує розподiл газу i води в поровому просторi шару залежно вiд кiлькостi накопиченого в ньому га- зу. В межах моделi обчисленi ефективнi пружнi модулi областей пористого шару, насичених газом i водою. Сформульовано початково-крайову задачу динамiки пружних хвиль у структурi та iз застосуванням перетворення Фур’є отримано ї ї розв’язок. Iз використанням отриманого розв’язку дослiджено картину хвильового поля на вiльнiй поверхнi структури залежно вiд кiлькостi газу, нагромадженого в пористому шарi. Введено та чисельно дослiджено характеристики, якi пов’язують параметри хвильового поля на вiльнiй поверхнi iз кiлькiстю газу, нагромадженого в пористому шарi. Отриманi результати можна застосувати для розроблення дистанцiйних методiв облiку кiлькостi природного газу в пiдземних сховищах газу, споруджених у водоносних горизонтах. | uk_UA |
