含薄互储集层半空间中点源激发的地震波场的理论求解
THEORETICAL SOLUTION OF SEISMIC SOUND FIELD EXCITED BY A SEISMIC FOCUS IN LAYERED MEDIA CONTAINING A THIN RESERVOIR
【摘要】 应用 Biot 双相介质的波动理论,严格推导了含有双相介质层(油储集层)时点源激发的表面位移的 Fouri-er-Bessel 积分解.自然地将储集层岩性参致(孔隙度、粘滞系数、渗透率等)纳入积分解中.
【Abstract】 The authors use the Blot’s theory of elastic wave in porous medium and get a Fourier-Bessel in- tegral solution of surface displacement of the secimic sound field excited by seismic focus in layered media which contains a thin reservoir.Naturally,it takes the porous parameter(porosity,viscosity of the pore fluid,permeability of porous medium)into the solution.
